fatigue following a
soccer match is multifactorial and related to dehydration,
glycogen depletion, muscle damage and mental fatigue. A
multitude of recovery strategies are currently implemented
in professional soccer clubs to target these causes of fatigue.
Recovery strategies aimed at reducing acute inflammation
from muscle damage and enhancing its rate of removal are
particularly used in professional soccer settings.

A CWI placebo is also as effective as
CWI itself in the recovery of muscle strength over 48 h.
This can likely be attributed to improved subjective ratings
of pain and readiness for exercise, suggesting that the hy-
pothesized physiological benefits surrounding CWI may
be at least partly placebo related.

There were
no significant group differences between control and either of the cold water immersion interventions. Seated cold water
immersion was associated with lower DOMS than standing cold water immersion (effect size = 1.86; P = 0.001). These
data suggest that increasing hydrostatic pressure by standing in cold water does not provide an additional recovery benefit
over seated cold water immersion, and that both seated and standing immersions have no benefit in promoting recovery
HIGH-INTENSITY CIRCUIT TRAINING USING BODY WEIGHTFernando Farias
Traditionally, resistance training often is
performed separately from aerobic training V
typically on two or three nonconsecutive days
each week. The American College of Sports
Medicine (ACSM) recommends 8 to 12 repeti-
tions of a resistance training exercise for each
major muscle group at an intensity of 40% to 80%
of a one-repetition max (RM) depending on the
training level of the participant.
Cold water immersion versus whole body cryotherapyFernando Farias
Cold-water immersion was more effective in
accelerating recovery kinetics than whole-body cryotherapy for countermovement jump
performance at 72h post-exercise. Cold-water immersion also demonstrated lower soreness
and higher perceived recovery levels across 24-48h post-exercise.
EFFECTS OF STRENGTH TRAINING ON SQUAT AND SPRINT PERFORMANCE IN SOCCER PLAYERSFernando Farias
We have demonstrated that a simple in-season strength training program resulted in an improvement in maximal back squat performance, which was reflected in improve- ments in short sprint performance, as identified by a decrease in sprint time over 5, 10, and 20 m, in professional soccer players, in line with the hypotheses. Furthermore, the changes in relative 1RM squat strength demonstrate strong associations with the changes in 5 (r = 0.62), 10 (r = 0.78), and 20-m (r = 0.60) sprint performances.
Does strength training change your movement patterns?Fernando Farias
Most of us in this industry believe that good movement patterns make someone
a better athlete, as well making them less likely to get injured. Unsurprisingly,
therefore, a lot of programs have been put together to help you improve your
movement patterns.

To analyze the effects of two resistance training (RT) programs that used the same relative loading but different repetition volume, using the velocity loss during the set as the independent variable: 15% (VL15) vs. 30% (VL30). Methods: Sixteen professional soccer players with RT experience (age 23.8 ± 3.5 years, body mass 75.5 ± 8.6 kg) were randomly assigned to two groups: VL15 (n = 8) or VL30 (n = 8) that followed a 6-week (18 sessions) velocity-based squat training program. Repetition velocity was monitored in all sessions. Assessments performed before (Pre) and after training (Post) included: estimated one- repetition maximum (1RM) and change in average mean propulsive velocity (AMPV) against absolute loads common to Pre and Post tests; countermovement jump (CMJ); 30-m sprint (T30); and Yo-yo intermittent recovery test (YYIRT).
Recovery in Soccer Part I – Post-Match Fatigue and Time Course of RecoveryFernando Farias
In elite soccer, players are frequently required to play consecutive matches

to alleviate post-match fatigue, regain performance faster and reduce the risk
of injury. This article is Part I of a subsequent companion review and deals
with post-match fatigue mechanisms and recovery kinetics of physical per-

athletes as a means of accelerating recovery and improving perform-

evaluating in vivo changes in tissue oxygenation during cold water
immersion may help further our understanding of this recovery
modality. This study aimed to investigate the effects of cold water
immersion on muscle oxygenation and performance during repeated
bouts of fatiguing exercise in a group of healthy young adults.
Melhorar ou até mesmo manter o desempenho atlético em jogadores de esportes de equipe competitivos durante o longo período da temporada é um dos maiores desafios para qualquer treinador comprometido. Tempo muito limitado está disponível entre as partidas semanais para introduzir sessões intensivas de treinamento de força e poder, com uma freqüência normal de 1-2 unidades por semana. Este fato estimula a busca de métodos de treinamento mais eficientes capazes de melhorar uma ampla variedade de habilidades funcionais, evitando ao mesmo tempo os efeitos de fadiga.
Differing from moderate-intensity aerobic exercise, high-intensity interval training
(HIIT) consists of alternating short periods of intense exercise with recovery
periods of passive or mild-intensity movement. Typically, the work intervals last
from 15 seconds to 4 minutes and approach 80% to 95% of an individual’s
maximum heart rate. Recovery intervals are generally equal to or slightly longer
than the intense work interval and consist of passive rest or mild activity at 40% to
50% of the maximum heart rate. The combined work/rest interval commonly is
repeated 6 to 10 times. Thus, the total HIIT exercise time ranges from 10 to 40 or
more minutes depending on the actual duration of the work and rest periods

Manipulating the rest-recovery interval between sets of resistance exercise may influence
training-induced muscle remodelling. The aim of this study was to determine the acute muscle
anabolic response to resistance exercise performed with short or long inter-set rest intervals.
In a study with a parallel-group design, 16 males completed four sets of bilateral leg-press and
knee-extension exercise at 75% of one-repetition maximum to momentary muscular failure,
followed by ingestion of 25 g of whey protein. Resistance exercise sets were interspersed by
1 min (n = 8) or 5 min of passive rest (n = 8). Muscle biopsies were obtained at rest, 0, 4, 24
and 28 h postexercise during a primed continuous infusion of l-[ring-13C6]phenylalanine to
determine myofibrillar protein synthesis and intracellular signalling.

Epidemiological studies have consistently shown hamstring
strain injuries (HSIs) to have a high prevalence rate in many
sports, such as sprinting (11%; Lysholm & Wiklander, 1987),
Australian Rules Football (16–23%; Orchard, 2001; Orchard,
Marsden, Lord, & Garlick, 1997) and football (12–14%:
Ekstrand, Hagglund, & Walden, 2011; Hawkins, Hulse,
Wilkinson, Hodson, & Gibson, 2001). The epidemiology and
aetiology of HSI in football has received extensive attention in
the scientific literature (Ekstrand et al., 2011; Woods et al., 2004),
given the economic burden associated with professional
players missing training and competitive fixtures (Woods,

Acute cardiopulmonary and metabolic responses to high intensity interval trai...Fernando Farias
Results from the present study quantify the effects of altering either the intensity of the
work or the recovery interval when performing interval sessions consisting of 60s of work and
60s of recovery for multiple repetitions. The information provided may aid those interested in
designing interval training sessions by providing ranges of values that could be expected for
individuals who possess moderate levels of cardiopulmonary fitness. Using a work intensity of
80% or 100% VGO2peak and a recovery intensity of 0% or 50% VGO2peak, subjects were able to
exercise within the ACSM recommended range for exercise intensity. Based upon the data it
would appear that a protocol such as the 80/0 may be appropriate for those individuals who
are just beginning a program or have little experience with interval-type activity. By contrast, a
100/50 protocol could not be completed by all of the subjects and therefore may be too intense
for some individuals.
The effect of various cold‑water immersion protocolsFernando Farias
CWI for 10 min at 10 °C appears very likely to be more
effective than passive recovery at restoring force generating
capacity of muscle in a SSC, but no CWI protocol used in
the current study was effective at restoring performance in
a purely concentric movement. CWI does not attenuate the
inflammatory response to an acute bout of normothermic
high-intensity intermittent sprint exercise when compared
with passive recovery. 30-min immersions to the iliac crest
in both cool (20 °C) and cold (10 °C) water appear to exac-
erbate specific aspects of the exercise-induced inflammatory
response. Performance effects CWI used following normo-
thermic sprint exercise are not likely a result of attenuation
of the inflammatory response to this type of exercise.
Training Load and Fatigue Marker Associations with Injury and IllnessFernando Farias
This paper provides a comprehensive review of the litera-
ture that has reported the monitoring of longitudinal
training load and fatigue and its relationship with injury
and illness. The current findings highlight disparity in the
terms used to define training load, fatigue, injury and ill-
ness, as well as a lack of investigation of fatigue and
training load interactions. Key stages of training and
competition where the athlete is at an increased risk of
injury/illness risk were identified. These included periods
of training load intensification, accumulation of training
load and acute change in load. Modifying training load
during these periods may help reduce the potential for
injury and illness.

The architectural and morphological adaptations of the hamstrings in response to training
33 with different exercises have not been explored. PURPOSE: To evaluate changes in biceps
34 femoris long head (BFLH) fascicle length and hamstring muscle size following 10-weeks of
35 Nordic hamstring exercise (NHE) or hip extension (HE) training. METHODS: Thirty
36 recreationally active male athletes (age, 22.0 ± 3.6 years, height, 180.4 ± 7 cm, weight, 80.8 ±
37 11.1 kg) were allocated to one of three groups: 1) HE training (n=10), NHE training (n=10),
38 or no training (CON) (n=10). BFLH fascicle length was assessed before, during (Week 5) and
39 after the intervention with 2D-ultrasound. Hamstring muscle size was determined before and
40 after training via magnetic resonance imaging.
Acute effect of different combined stretching methodsFernando Farias
The purpose of this study was to investigate the acute effect of different stretching methods, during a warm-up,
on the acceleration and speed of soccer players. The acceleration performance of 20 collegiate soccer players (body height:
177.25 ± 5.31 cm; body mass: 65.10 ± 5.62 kg; age: 16.85 ± 0.87 years; BMI: 20.70 ± 5.54; experience: 8.46 ± 1.49
years) was evaluated after different warm-up procedures, using 10 and 20 m tests. Subjects performed five types of a
warm-up: static, dynamic, combined static + dynamic, combined dynamic + static, and no-stretching. Subjects were
divided into five groups. Each group performed five different warm-up protocols in five non-consecutive days. The
warm-up protocol used for each group was randomly assigned. The protocols consisted of 4 min jogging, a 1 min
stretching program (except for the no-stretching protocol), and 2 min rest periods, followed by the 10 and 20 m sprint
test, on the same day. The current findings showed significant differences in the 10 and 20 m tests after dynamic
stretching compared with static, combined, and no-stretching protocols. There were also significant differences between
the combined stretching compared with static and no-stretching protocols. We concluded that soccer players performed
better with respect to acceleration and speed, after dynamic and combined stretching, as they were able to produce more
force for a faster execution.
Cold water inmersion reduces anaerobic performanceFernando Farias
Many athletes compete in multiple events on the
same day such as heats and semifinals or round
robin competitions. Under these circumstances,
effective recovery is essential to ensure optimal
performance in a subsequent event or match. A
variety of recovery techniques exist including
cryotherapy (cold water immersion/ice baths,
ice massage, ice packs), whirlpool therapy, mas-
sage and contrast therapy.
Does static stretching reduce maximal muscle performance?Fernando Farias
Kay and Blazevich systemati-
cally examined research that showed
the effects of static stretching on mus-
cle strength and other performance
measures by separating the studies into
total stretch durations of ,30 seconds,
30 to 45 seconds, 1 to 2 minutes, or
.2 minutes. Some practical and tech-
nical considerations may be helpful in
considering their conclusion that static
stretching only impairs muscle function
with longer stretches.
Differences in strength and speed demands between 4v4 and 8v8 SSGFernando Farias
Small-sided games (SSGs) have been extensively used in training
footballers worldwide and have shown very good efficacy in
improving player performance (Hill-Haas, Dawson, Impellizzeri,
& Coutts, 2011). As an example, it has been shown that the
technical performance (Owen, Wong del, McKenna, & Dellal,
2011) and physical performance (Chaouachi et al., 2014; Dellal,
Varliette, Owen, Chirico, & Pialoux, 2012) of footballers can be
enhanced using SSG-based football training programmes.
In the last two decades, extensive research has been pub-
lished on physical and physiological response during SSGs in
football (for refs, see Halouani, Chtourou, Gabbett, Chaouachi,
& Chamari, 2014). It was found that the time-motion charac-
teristics of SSGs could vary greatly depending on certain
structural (e.g., pitch size, number of players, type and number
of goals) and rule (e.g., number of ball touches) constraints.
For example, it was observed that higher maximum speeds are
reached during SSGs played on bigger pitches (Casamichana &
Castellano, 2010). Furthermore, heart rate (HR) and lactate
concentrations were shown to be sensitive to structural and
rule changes in SSGs.
How Small-Sided and Conditioned Games Enhance Acquisition of Movement and Dec...Fernando Farias
Such traditional methods provide a limited scope for
action variability in learners because a key aim of practitioners
is to decrease uncertainty of actions and rationalize decision-
making processes in training drills. Despite these reported bene-
fits, traditional utilization of practice drills has been criticized
because they neglect the active role of the performance envi-
ronment in shaping movement behavior and decision making
(10), sustaining a dysfunctional rupture in the performer-
environment relationship (cf. the concept of organismic asym-
metry in sports science (9)).

warm-up: static, dynamic, combined static + dynamic, combined dynamic + static, and no-stretching. Subjects were
divided into five groups. Each group performed five different warm-up protocols in five non-consecutive days. The
warm-up protocol used for each group was randomly assigned. The protocols consisted of 4 min jogging, a 1 min
stretching program (except for the no-stretching protocol), and 2 min rest periods, followed by the 10 and 20 m sprint
test, on the same day. The current findings showed significant differences in the 10 and 20 m tests after dynamic
stretching compared with static, combined, and no-stretching protocols. There were also significant differences between
the combined stretching compared with static and no-stretching protocols. We concluded that soccer players performed
better with respect to acceleration and speed, after dynamic and combined stretching, as they were able to produce more
force for a faster execution.
Cold water inmersion reduces anaerobic performanceFernando Farias
Many athletes compete in multiple events on the
same day such as heats and semifinals or round
robin competitions. Under these circumstances,
effective recovery is essential to ensure optimal
performance in a subsequent event or match. A
variety of recovery techniques exist including
cryotherapy (cold water immersion/ice baths,
ice massage, ice packs), whirlpool therapy, mas-
sage and contrast therapy.
Does static stretching reduce maximal muscle performance?Fernando Farias
Kay and Blazevich systemati-
cally examined research that showed
the effects of static stretching on mus-
cle strength and other performance
measures by separating the studies into
total stretch durations of ,30 seconds,
30 to 45 seconds, 1 to 2 minutes, or
.2 minutes. Some practical and tech-
nical considerations may be helpful in
considering their conclusion that static
stretching only impairs muscle function
with longer stretches.
Differences in strength and speed demands between 4v4 and 8v8 SSGFernando Farias
Small-sided games (SSGs) have been extensively used in training
footballers worldwide and have shown very good efficacy in
improving player performance (Hill-Haas, Dawson, Impellizzeri,
& Coutts, 2011). As an example, it has been shown that the
technical performance (Owen, Wong del, McKenna, & Dellal,
2011) and physical performance (Chaouachi et al., 2014; Dellal,
Varliette, Owen, Chirico, & Pialoux, 2012) of footballers can be
enhanced using SSG-based football training programmes.
In the last two decades, extensive research has been pub-
lished on physical and physiological response during SSGs in
football (for refs, see Halouani, Chtourou, Gabbett, Chaouachi,
& Chamari, 2014). It was found that the time-motion charac-
teristics of SSGs could vary greatly depending on certain
structural (e.g., pitch size, number of players, type and number
of goals) and rule (e.g., number of ball touches) constraints.
For example, it was observed that higher maximum speeds are
reached during SSGs played on bigger pitches (Casamichana &
Castellano, 2010). Furthermore, heart rate (HR) and lactate
concentrations were shown to be sensitive to structural and
rule changes in SSGs.
How Small-Sided and Conditioned Games Enhance Acquisition of Movement and Dec...Fernando Farias
Such traditional methods provide a limited scope for
action variability in learners because a key aim of practitioners
is to decrease uncertainty of actions and rationalize decision-
making processes in training drills. Despite these reported bene-
fits, traditional utilization of practice drills has been criticized
because they neglect the active role of the performance envi-
ronment in shaping movement behavior and decision making
(10), sustaining a dysfunctional rupture in the performer-
environment relationship (cf. the concept of organismic asym-
metry in sports science (9)).

Assess The Effect of Resistance Training Compared To a Weight Loss Diet Progr...IOSR Journals
To evaluate the effect of a Resistance training program (BT) versus weight loss diet (DR) on body composition, insulin sensitivity and cardiovascular risk factors in obese adolescents. Methods: Thirty obese adolescents with a BMI above the 97th percentile participated in a training program and diet for 12 weeks. They were randomized into two groups: a diet group (DR, n = 16) with a caloric restriction of 500 kcal / day and Strength training group (BT, n = 14) for all major muscle groups, three sessions / week with an intensity of 50-80% (1.RM) for 3 months. Anthropometric and biochemical measurements were performed for all of our subjects before and after the intervention program of 12 weeks. Results: Significant variations of body composition parameters were observed in both groups. The decrease of BMI, body weight, fat mass and (WC) for the group (DR) was more important than the group (BT) (p <0.01><0.05><0.05)),><0.05).><0.05) respectively). Conclusion: Strength training improves much more the sensitivity to insulin and cardiovascular risk factors than weight loss diet program. The latter is more effective for weight loss, BMI and body fat in obese adolescent boys.
A universalidade das Regras do Jogo significa que o jogo é essencialmente o
mesmo em todas as partes do mundo e em todos os níveis. Bem como promover um
ambiente justo e seguro para a sua prática, as Regras também devem promover a
participação e a diversão.
O jogo deve ser jogado e arbitrado da mesma maneira em todos os campos de
futebol pelo mundo, desde a final da Copa do Mundo FIFA™ até um jogo em um
vilarejo remoto. No entanto, as características locais de cada país devem determinar
a duração da partida, quantas pessoas podem participar e como algumas atitudes
inapropriadas devem ser punidas.
Os resultados atuais indicaram que a ocorrência de lesões de isquiotibiais podem estar associadas a uma mudança hierárquica na distribuição da atividade metabólica dentro do complexo muscular do isquiotibial após o trabalho excêntrico em que o Semitendinoso provavelmente deveria tomar a parte principal, seguido pelo BÍceps Femural e Semimembranoso. Quando o BF aumenta sua contribuição e é ativado em uma extensão proporcionalmente maior, o risco de sofrer uma lesão do isquiotibial pode aumentar substancialmente.
To examine the acute effects of generic (Running Drills, RD) and specific (Small-
Sided Games, SSG) Long Sprint Ability (LSA) drills on internal and external load of male
soccer-players. Methods: Fourteen academy-level soccer-players (mean±SD; age 17.6±0.61
years, height 1.81±0.63 m, body-mass 69.53±4.65 kg) performed four 30s LSA bouts for
maintenance (work:rest, 1:2) and production (1:5) with RD and SSG drills. Players’ external-
load was tracked with GPS technology (20Hz) and heart-rate (HR), blood-lactate
concentrations (BLc) and rate of perceived exertion (RPE) were used to characterize players’
internal-load. Individual peak BLc was assessed with a 30s all-out test on a non-motorized
treadmill (NMT). Results: Compared to SSGs the RDs had a greater effect on external-load
and BLc (large and small, respectively). During SSGs players covered more distance with
high-intensity decelerations (moderate-to-small). Muscular-RPE was higher (small-to-large)
in RD than in SSG. The production mode exerted a moderate effect on BLc while the
maintenance condition elicited higher cardiovascular effects (small-to-large). Conclusion:
The results of this study showed the superiority of generic over specific drills in inducing
LSA related physiological responses. In this regard production RD showed the higher post-
exercise BLc. Interestingly, individual peak blood-lactate responses were found after the
NMT 30s all-out test, suggesting this drill as a valid option to RD bouts. The practical
physiological diversity among the generic and specific LSA drills here considered, enable
fitness trainers to modulate prescription of RD and SSG drills for LSA according to training
schedule.
A evidência apresentada sugere que a variação é um componente necessário do planejamento efetivo do treinamento. Apoiando essa perspectiva, outras pesquisas sugerem que a monotonia de treinamento elevado - que pode ser amplamente percebida como uma falta de variação20 - leva a uma maior incidência de síndromes de overtraining21, um mau desempenho e freqüência de infecções banais.22 Inversamente, as reduções na monotonia têm Tem sido associada a uma maior incidência de melhor desempenho pessoal 22, e os índices de monotonia têm sido defendidos como ferramentas benéficas de treinamento-regulação na elite rowing23 e no sprint24.

A literatura atual que mede os efeitos de SMR ainda está emergindo. Os resultados desta análise sugerem que o rolamento de espuma e a massagem com rolo podem ser intervenções eficazes para melhorar a ROM conjunta e o desempenho muscular pré e pós-exercício. No entanto, devido à heterogeneidade dos métodos entre os estudos, atualmente não há consenso sobre o ótimo programa SMR.
Actualmente la capacidad de repetir sprints es considerada fundamental en el rendimiento del fútbol por
parecerse al patrón de movimiento que se da en el mismo. De esta manera su entrenamiento resulta fundamental
en cualquier planificación. Así, se deben trabajar aquellos aspectos que la limitan para poder acceder a un mayor
rendimiento. Una vez conocido esto se debería elegir la forma en la que se quiere entrenar, teniendo para ello
métodos analíticos (interválico, intermitente) y contextualizados (espacios reducidos). Por último, se proponen
una series de variables de entrenamiento para el trabajo de repetir sprints, orientándolo no solo al aspecto físico,
sino también al técnico, táctico y psicológico, conformando, por tanto, un entrenamiento integrado en el fútbol.
Maximal sprinting speed of elite soccer playersFernando Farias
Current findings might help individuals involved within the physical preparation of players (e.g. technical coaches, fitness coaches, and sport science staff) when developing training programs and training sessions in line with the playing positions, and with the levels of high speed running targeted to reach during specific training drills like sided-games.
Indeed, the closer to match-play situations regarding the rules with goals, goalkeepers, the larger pitch sizes and greater number of players involved, the higher sprinting speed running players would reach during sided-games. However, coaches are advised to add specific speed drills to sided-games in order to elicit a stimulus of high-speed running high enough to prepare players for competition.
Sprint running acceleration is a key feature of physical performance in team sports, and recent
literature shows that the ability to generate large magnitudes of horizontal ground reaction force
and mechanical effectiveness of force application are paramount. We tested the hypothesis that
very-heavy loaded sled sprint training would induce an improvement in horizontal force
production, via an increased effectiveness of application. Training-induced changes in sprint
performance and mechanical outputs were computed using a field method based on velocity-
time data, before and after an 8-week protocol (16 sessions of 10x20-m sprints). 16 male
amateur soccer players were assigned to either a very-heavy sled (80% body-mass sled load)
or a control group (unresisted sprints). The main outcome of this pilot study is that very-heavy
sled resisted sprint training, using much greater loads than traditionally recommended, clearly
increased maximal horizontal force production compared to standard unloaded sprint training
(effect size of 0.80 vs 0.20 for controls, unclear between-group difference) and mechanical
effectiveness (i.e. more horizontally applied force; effect size of 0.95 vs -0.11, moderate
between-group difference)
Hip extension and Nordic hamstring exercise training both promote the elongation of
biceps femoris long head fascicles, and stimulate improvements in eccentric knee
flexor strength.
Hip extension training promotes more hypertrophy in the biceps femoris long head
and semimembranosus than the Nordic hamstring exercise, which preferentially
develops the semitendinosus and the short head of biceps femoris

and investigations of anatomical specimens are not consistent with the text-
book description. We have found a second tensor-like muscle between the
vastus lateralis (VL) and the vastus intermedius (VI), hereafter named the

Hamstring strain prevention in elite soccer playersFernando Farias
Hamstring strains are among the most
common injury in sport and are most
often observed in sports that involve
sprinting, turning, and jumping
(8,38,63). The prevalence of hamstring
strains has been measured between 11
and 16% in studies of soccer, Australian
rules football, and cricket (92). This can
result in an average of 6 players per squad
suffering a hamstring injury (defined as
“preventing player participation in
a match”) each season in professional
soccer and Australian rules football
Hamstring injuries are among the most com-
mon non-contact injuries in sports. The Nordic hamstring
(NH) exercise has been shown to decrease risk by
increasing eccentric hamstring strength.
Bilateral and unilateral vertical ground reaction forcesFernando Farias
The purposes of this study were to assess unilateral and bilateral vertical jump performance

Abstract In the formerly published part I of this two-part
review, we examined fatigue after soccer matchplay and
recovery kinetics of physical performance, and cognitive,
subjective and biological markers. To reduce the magni-
tude of fatigue and to accelerate the time to fully recover
after completion, several recovery strategies are now used
in professional soccer teams. During congested fixture
schedules, recovery strategies are highly required to alle-
viate post-match fatigue, and then to regain performance
faster and reduce the risk of injury. Fatigue following
competition is multifactorial and mainly related to dehy-
dration, glycogen depletion, muscle damage and mental
fatigue. Recovery strategies should consequently be tar-
geted against the major causes of fatigue. Strategies
reviewed in part II of this article were nutritional intake,
cold water immersion, sleeping, active recovery, stretch-
ing, compression garments, massage and electrical stimu-
lation. Some strategies such as hydration, diet and sleep are
effective in their ability to counteract the fatigue mecha-
nisms. Providing milk drinks to players at the end of
competition and a meal containing high-glycaemic index
carbohydrate and protein within the hour following the
match are effective in replenishing substrate stores and
optimizing muscle-damage repair. Sleep is an essential part
of recovery management. Sleep disturbance after a match
is common and can negatively impact on the recovery
process. Cold water immersion is effective during acute
periods of match congestion in order to regain performance
levels faster and repress the acute inflammatory process.
Scientific evidence for other strategies reviewed in their
ability to accelerate the return to the initial level of per-
formance is still lacking. These include active recovery,
stretching, compression garments, massage and electrical
stimulation. While this does not mean that these strategies
do not aid the recovery process, the protocols implemented
up until now do not significantly accelerate the return to
initial levels of performance in comparison with a control
condition. In conclusion, scientific evidence to support the
use of strategies commonly used during recovery is lack-
ing. Additional research is required in this area in order to
help practitioners establish an efficient recovery protocol
immediately after matchplay, but also for the following
days. Future studies could focus on the chronic effects of
recovery strategies, on combinations of recovery protocols
and on the effects of recovery strategies inducing an anti-
inflammatory or a pro-inflammatory response.
1 Introduction
In the formerly published part I of this two-part review [1],
we reviewed dehydration, glycogen depletion, muscle
damage, inflammation, oxidative stress and mental fatigue
as potential factors associated with magnitude of fatigue
following a soccer match. A recovery strategy involves the
implementation of a technique or a combination of tech-
niques in order to accelerate the time to achieve full
recovery and potentially reduce the risk of injury [2, 3].

2. This review summarizes current research that evaluates
recovery strategies, using soccer (Association Football) as
the main sport of interest. A computerized literature search
was performed using PubMed between January 2011 and
January 2012. The following keywords were used in
different combinations: ‘soccer’, ‘football’, ‘recovery’,
‘modality’, ‘strategy’, ‘nutrition’, ‘diet’, ‘hydration’,
‘inflammation’, ‘cryotherapy’, ‘cold water immersion’,
‘cold bath’, ‘contrast therapy’, ‘sleep’, ‘active recovery’,
‘stretching’, ‘compression garments’, ‘massage’, ‘electrical
stimulation’ and ‘electromyostimulation’. All titles and
abstracts were carefully read and relevant articles were
retrieved for review. In addition, the reference lists from both
original and review articles retrieved were also reviewed.
According to Bishop [4], key gaps in the evidence
informing sports practice will only be recognized when the
sport-science community frequently consults the evidence
base for answers [4]. Scientific research guides practice,
but practice can also guide research and a survey about the
current recovery strategies used in elite soccer was per-
formed in March 2011. Following a literature search using
PubMed to establish a complete list of recovery strategies,
32 practitioners in charge of recovery strategies in French
professional soccer teams were questioned on the strategies
they implemented. The results showed that cold water
immersion and contrast water therapy (88% of teams),
active recovery (81%), massage (78%), stretching (50%),
compression garments (22%) and electrical stimulation
(13%) were the strategies used. Nutrition and hydration
were considered as very effective recovery strategies by
97% of the practitioners, while sleep was also considered
as an effective recovery strategy (95% of practitioners).
In part II of this review, the advantages and the limits of
these recovery strategies are discussed in an attempt to
select the most appropriate strategy/ies following a single
soccer match and/or a period of match congestion.
2 Nutritional Strategies
As presented in part I [1], rehydration, carbohydrate and
protein consumption after a match are effective recovery
techniques for replenishing water and substrate stores, and
optimizing muscle-damage repair. However, guidelines
including quantity, timing and composition are required in
order to maximize their effectiveness.
After match-induced dehydration (*2% of body mass),
research has shown that consumption of a high sodium
drink (61 mmol/L) equivalent to 150–200% of sweat loss is
sufficient to attain a state of hyperhydration 6 h after
ingesting the drink [5].
To optimize the resynthesis of muscle glycogen stores, a
high glycaemic index (GI) carbohydrate intake at the end
of a match is necessary. An intake of *1.2 g carbohydrate/
kg/h with a high GI immediately after a match, and at
15–60 min intervals for up to 5 h [6], enables maximum
resynthesis of muscle glycogen stores. However, the effect
of high-carbohydrate meals with high GI on subsequent
soccer-specific performance is still unclear [7]. When a
lower amount of carbohydrate is consumed, co-ingestion of
protein (0.4 g/kg/h) could be useful to increase post-exer-
cise muscle glycogen-synthesis rates, as it may stimulate
insulin secretion, glucose uptake and muscle glycogen
synthase [6]. Nevertheless, Gunnarsson et al. [8] failed to
find an increase in glycogen resynthesis 48 h after a soccer
match following ingestion of a whey protein and carbo-
hydrate-enriched diet compared with a normal diet. As
exercise stimulates muscle protein synthesis and muscle
protein breakdown, the absence of protein intake after
exercise can lead to a negative net protein balance [9].
Indeed, a positive muscle protein balance is required to
repair exercise-induced muscle damage [10], which is
common following a soccer match [1]. Protein consump-
tion stimulates muscle protein synthesis [11] necessary for
positive muscle protein balance; although, the quantity,
type and timing of protein ingestion to maximize post-
exercise muscle protein synthesis remains a topic for
debate, a consumption of *20 g milk protein, or an
equivalent of *9 g essential amino acids, seems to be
sufficient to stimulate muscle protein synthesis rates during
the first 2 h of post-exercise recovery [12]. A high-protein
diet with branched chain amino acids also positively
impacts other factors associated with recovery such as
mental performance or sensation of fatigue [13]. The
addition of protein to post-exercise carbohydrate feedings
can reduce muscle soreness [14, 15] and decrease the
creatine kinase (CK) concentration [15–17] and myoglobin
concentration [17, 18]. It can also improve subsequent
muscle function [17, 18] and cycling performance exercise
[16] in comparison with a simple carbohydrate beverage.
Following a match, flavoured milk, which is an easily
accessible and relatively inexpensive dairy product, could
be an effective beverage for post-exercise recovery. It
contains carbohydrate and proteins in amounts similar to
those used in studies demonstrating improved post-exercise
recovery. Numerous studies have confirmed the significant
effects of post-exercise chocolate milk supplementation on
subsequent exercise performance [17, 19–22], intracellular
signalling stimulus for protein synthesis [21], perceived
soreness [23], and CK levels [24].
Other studies have found that omega-3 fatty acids,
curcumin, tart cherry juice and tomato juice improve the
recovery process due to their anti-inflammatory and anti-
oxidant effects. Increased omega-3 concentrations in the
blood are associated with decreased levels of proinflam-
matory markers (interleukin [IL]-6, IL-1ra, tumour necrosis
10 M. Ne´de´lec et al.
3. factor [TNF]-a, and C-reactive protein [CRP]), and higher
levels of anti-inflammatory markers (soluble IL-6r, IL-10,
and transforming growth factor [TGF]-b) [25]. Tartibian
et al. [26] showed the effectiveness of supplementing
subjects during 30 days with 1.8 g/day omega-3 fatty acids
on lower limb soreness 48 h after eccentric knee extensors
exercise. The authors suggested that their findings were due
to the anti-inflammatory effects of omega-3 family fatty
acids. Nevertheless, evidence of the effectiveness of
omega-3 fatty acids in improving physical performance
measures post-exercise is lacking [27, 28]. The quantities
employed in these studies could be provided in daily food
intakes through consumption of a diet rich in a-linolenic
acid (e.g. linseed oil, rapeseed oil), eicosapentaenoic acid
and docosahexaenoic acid omega-3 fatty acids (e.g.
salmon, mackerel, anchovies). Curcumin also exhibits
anti-inflammatory properties and Davis et al. [29] showed
that feeding mice with curcumin (10 mg) daily for 3 con-
secutive days prior to downhill running significantly offsets
the decrement in running performance (i.e. treadmill run
time to fatigue, p 0.01; voluntary wheel running activity,
p 0.05) and significantly (p 0.05) blunted the increase
in inflammatory cytokines IL-1b, IL-6, TNF-a and CK
compared with mice fed with a placebo. Curcumin intake
requires further investigation in humans during the post-
exercise recovery period. Tart cherry juice is also shown to
enhance the recovery process. Tart cherries are loaded with
antioxidant anthocyanins, which exhibit in vitro antioxi-
dant and anti-inflammatory activities [30]. Connolly et al.
[31] demonstrated that a daily dose of 0.682 L for 4 days
prior to and 4 days following eccentric contractions of the
elbow flexors reduced muscle soreness and attenuated the
loss in muscle force. In an investigation of the efficacy of
tart cherry juice consumed before the day of a marathon
run and for 48 h following the run, Howatson et al. [32]
showed that the group who ingested the cherry juice
recovered isometric strength significantly faster (p 0.05)
and exhibited reduced inflammation (IL-6, p 0.001;
CRP, p 0.01; uric acid concentrations, p 0.05) and
greater total antioxidant status (p 0.05) compared with
the placebo group during recovery. The authors assumed
that consumption of the cherry juice may have blunted the
secondary muscle damage response, resulting in a more
rapid return of strength in the cherry juice group versus
placebo. Ramaswamy and Indirani [33] found that 75 mL
of tomato juice (containing 10 lg of lycopene) consumed
for 60 days after each training session had a beneficial
effect on the oxidative stress and on the athletic perfor-
mance of athletes involved in track events. All of the
studies detailed above examining the effectiveness of
nutrients on the recovery process have focused on recovery
from non-soccer-specific exercises. Thus, the relevance of
this evidence in improving recovery between matches in
elite soccer players remains to be demonstrated.
It is generally recognized that certain nutrients posi-
tively influence the recovery process. In contrast, alcohol
consumption can negatively affect a player’s ability to
recover following exercise. Soccer players occasionally
ingest moderate to large volumes of alcohol (ethanol) in the
hours after matchplay. Barnes et al. [34] investigated the
effects of acute moderate alcohol intake (1 g/kg body-
weight ethanol as vodka and orange juice) on muscular
performance during recovery from eccentric exercise-
induced muscle damage. The results showed that peak
strength loss at 36 h post-exercise was significantly greater
in the alcoholic beverage condition compared with an
isocaloric non-alcoholic beverage condition. A combina-
tion of decreased inflammatory response, altered cytokine
production and abnormal reactive oxygen intermediate
generation after alcohol exposure may hinder the muscle
repair and recovery process [35]. To minimize exercise-
related losses in muscle function and accelerate recovery,
participants in sports involving frequent eccentric muscle
work, such as soccer, should consequently avoid alcohol-
containing beverages in the post-event period [34]. Apart
from hindering the muscle repair process, alcohol con-
sumption may also delay the recovery from dehydration
[36].
To sum up, evidence suggests that flavoured milk
drinks should be given to players at the end of competi-
tion. In addition, a meal containing high-GI carbohydrate
and protein should be served to players within the hour
following play. Their habitual diet should include con-
sumption of omega-3 fatty acids. In addition, tart cherry
juice consumed before the match, on the day of the match
and on the following days could be provided to the
players, especially when two or three matches in 1 week
are to be played. We recommend, however, that the
effects of systematic consumption of this product on the
recovery process should be studied before recommending
its chronic consumption. Further research is needed to
determine when inflammation should be enhanced or
reduced after a soccer match. The outcomes would help to
select a nutritional plan in order to increase or decrease
the inflammatory response. Currently, the inflammatory
process is accentuated at the end of the match by con-
suming high-GI carbohydrate and protein in order to
increase the glycogen stores and muscle function and to
decrease muscle soreness. Finally, future studies may
investigate if it is necessary to adapt nutritional recovery
strategies according to playing position and/or individual
activity performed during the match. For example, a
spontaneous higher carbohydrate intake is observed for
players in a more ‘physically’ demanding position

goalkeepers and centrebacks [37].
3 Cold Water Immersion
The survey on recovery strategies used by professional
soccer teams revealed that cold water immersion and
contrast water therapy are the most common recovery
strategies employed in French professional soccer teams, as
these are currently used by 88% of teams. Cold water
immersion performed immediately after exercise and
repeated throughout the recovery process [38–42] has
proven to be a superior recovery modality when compared
with passive recovery, contrast water immersion [41] and
hot water immersion [40]. Therefore, this section deals
only with cold water immersion. Table 1 presents the
effects of cold water immersion on physical performance
and on subjective and biological markers following soccer-
specific exercise. Cold water (temperature range: 9–10 °C;
duration range: 10–20 min) immersion post-exercise pro-
vided worthwhile beneficial effects on anaerobic perfor-
mances, i.e. maximal strength [38, 41, 43, 44], sprint
ability [41] and countermovement jump [45]. Moreover,
cold water immersion was beneficial in reducing muscle
soreness [38, 41–47] and decreasing CK and myoglobin
concentrations [38, 43]. Cold water immersion protocols
are generally heterogeneous in terms of temperature,
duration and level of immersion [38–42] and the best
compromise has yet to be determined. Other cold water
immersion protocols (temperature range: 10–15 °C; dura-
tion range: 5–15 min) were all found to provide beneficial
effects on maximal strength [40, 48], sprint ability [39],
cycling performance [49] and rowing performance [48],
and reduced localized oedema [40]. However, these have
not been tested in soccer players. Time (e.g. immediately
after the match, delayed several hours after the match, or
the day after) and frequency of use are other important
issues related to cold water immersion. Work by Brophy-
Williams et al. [50] found that running performance on the
subsequent day between immediate cold water immersion
and delayed cold water immersion trials were similar
(p = 0.147), while qualitative analyses demonstrated that
immediate cold water immersion resulted in a 79% likely
benefit when compared with delayed cold water immer-
sion. The study demonstrates that cold water immersion
immediately after a high-intensity exercise session was
more beneficial for next-day running performance than
cold water immersion performed 3 h after the session.
The recovery benefits of cold water immersion are most
likely due to water temperature rather than hydrostatic
pressure [41, 42]. Full-body immersion in cold water at
15 °C for 15 min reduces blood flow to the legs and to the
arms, inducing a redirection of blood flow from the
periphery to the core and thereby improving venous return
and cardiac efficiency [49]. Cold water may also reduce
acute inflammation from muscle damage [51] and has a
short-term analgesic effect related to reduction of nerve
conduction velocity, muscle spindle activity, the stretch-
reflex response and spasticity, thus inhibiting the pain-
spasm cycle [52].
In contrast, cold water immersion following matchplay
can present some limitations. Although scientifically
unproven, the reduction in skeletal muscle blood flow
induced by cold water immersion could, in theory, alter
glucose availability to the muscle during recovery and
therefore alter the rate of post-exercise glycogen synthesis.
Additionally, using cold water immersion on a regular
basis may hinder exercise-induced adaptations. Yamane
et al. [53] proposed leg endurance training and forearm
flexor muscles resistance training 3–4 times a week for
4–6 weeks. Cold-water immersion was applied after each
training session to one leg and one arm of subjects, with the
other leg and the other arm resting at room temperature.
Significant training effects were three times higher in the
control group than in the ‘cold’ group (p 0.05), including
increases in artery diameter in the control group but not in
the cold group. The authors proposed partial suppression of
heat shock protein induction in the cooled relative to the
non-cooled muscles to explain that post-exercise cold
water immersion is an adverse treatment from the view-
point of physical training. Exercise induces heat shock
protein expression such as an increase in muscle temper-
ature [54]. As heat shock protein induction in training of
elite male rowers depends on exercise intensity and volume
[55, 56], cooling recovery strategies after each training
session should be avoided among elite athletes to allow
natural induction of heat shock protein, which is respon-
sible for long-term muscle adaptations. However, the study
by Yamane et al. [53] presents several limitations with
respect to the present review. Non-athlete subjects exer-
cised at an intensity below the threshold of delayed-onset
muscle soreness before immersing their leg for 40 min in
water at 5 °C. This model is unlikely to closely reflect the
physical demands of elite soccer players. Moreover, it
should not be excluded that the cooled limb recovered
better than the control limb during the training programme,
making the training stimulus too low to induce any training
effect in the cooled limb. In support of these limitations,
Howatson et al. [57] found that cold water immersion did
not inhibit the repeated bout effect when given four times
after the first of two bouts of drop jump exercise separated
by 14–21 days.
Generally, cold water immersion is an effective recov-
ery strategy during acute periods of fixture congestion to
improve physical performance and reduce muscle soreness.
12 M. Ne´de´lec et al.
6. Apart from these periods, and particularly during training
periods, it should be avoided to prevent treatment duration-
dependent interference with the repair and adaptive process
[58–60]. Additional studies on anti-inflammatory recovery
strategies are necessary to determine the optimal time after
exercise to implement the treatment. A biphasic recovery
pattern of muscle performance after exercise-inducing
muscle damage is reported, i.e. a rapid recovery related to
metabolic fatigue subsidence within the first hours after
exercise, followed by the second and slow phase of the
recovery during subsequent days related to the muscle
repair [61–64]. Implementing anti-inflammatory recovery
strategies according to the evolution of the inflammatory
response may increase their effectiveness.
4 Sleeping
Neurometabolic theories of sleep function propose that
sleep repays the neural and metabolic cost of waking [65].
Slow-wave sleep, which includes four distinct stages
(stages 1, 2, 3 and 4), is characterized by slow breathing, a
low heart rate, low cerebral blood flow and a large increase
of growth hormone secretion allowing physiological resti-
tution [66]. Both slow-wave sleep and rapid-eye-movement
sleep are implicated in the plastic cerebral changes that
underlie learning and memory [67–69]. In this respect, the
question of sleep in the recovery management should be
studied.
When playing an evening soccer match, professional
soccer players are subjected to a high physical and mental
work load, in addition to high emotional stress. Players
must perform at their peak when psychomotor vigilance
and subjective alertness tend to decrease after a typical day
of activity [70]. Irregular sleep-wake schedules influence
the homeostatic and circadian regulation of sleep and, in
turn, its quality and quantity [71]. Post-match routines (i.e.
medical care, recovery strategies, meals and the return trip)
frequently lead to a very late bedtime, which may also alter
sleep quality and quantity [72]. Another potential cause of
sleep disturbances after a match is waking several times
during the night because of hyperhydration [73]. As a
result, many players experience a disturbed night’s sleep
following competition, which can have multiple negative
consequences. As extensive sleep loss (i.e. 30 h of sleep
deprivation) is associated with reductions in muscle gly-
cogen content [74], and chronic sleep restriction (i.e.
restriction to 50% of the habitual time over 12 days) may
contribute to the amplification of soreness [75], future
studies are required to investigate the acute and chronic
effects of a disturbed night’s sleep after a match among
soccer players or over periods of match congestion. In
addition to its impact on sleep quantity, a night of sleep
loss is also characterized by sleep architecture disturbance.
Sallinen et al. [76] found that the proportion of stage 4
sleep is highest in the sleep debt condition but the pro-
portions of stages 1 and 2 sleep are lower during a night of
limited sleep than in the normal sleep condition. Addi-
tionally, sleep loss may impose a reduction in the ability to
commit new experiences to memory [77]. Close connec-
tions also exist between sleep and the immune system.
Cohen et al. [78] showed that subjects with less than 7 h of
sleep per night in the weeks preceding exposure to a rhi-
novirus are threefold more likely to develop a cold than
those with 8 h or more of sleep. Partial sleep deprivation
(being awake from 11:00 pm to 3:00 am) induces a functional
alteration of the monocyte pro-inflammatory cytokine
response and alters the expression of pro-inflammatory cyto-
kine genes [79]. In the morning after a night of sleep depri-
vation, inflammatory responses are enhanced compared with
morning levels following uninterrupted sleep [79]. Studies
on the link between sleep loss and illness in the elite soccer
player are warranted.
To counteract a disturbed night’s sleep among soccer
players, several factors have been proposed to improve
sleep after the match and during the following nights. A
high-GI carbohydrate, which is recommended for rapid
restoration of muscle glycogen stores [80], may also pos-
itively influence sleep. Afaghi et al. [81] showed that a
high-GI meal resulted in a significant shortening of sleep-
onset latency compared with a low-GI meal (9.0 min vs.
17.5 min, respectively; p 0.01) and was most effective
when consumed 4 h before bedtime compared with the
same high-GI meal given 1 h before bedtime (p = 0.01).
Sleep initiation depends on a thermophysiological cascade
with body heat loss promoting sleepiness and the rapid
onset of sleep [82]. Recovery strategies such as cold water
immersion reduce body temperature [49], which may
consequently promote sleep onset. Other recommendations
for sleep induction include benefiting from a dark and quiet
environment by using eye shades and ear plugs, listening to
relaxing music and adopting regular sleep-wake schedules
[83]. Conversely, consumption of caffeine prior to the
match for performance enhancement [84], consumption of
alcohol as a means of celebrating after the match [85], and
hyperhydration [73] potentially lead to sleep disturbance.
However, a poor night’s sleep may be compensated for by
a short post-lunch nap [86, 87]. Waterhouse et al. [87]
found that a nap followed by a 30-min recovery period
improves alertness and aspects of mental and physical
performance following partial sleep loss. The ability to nap
for short periods during the day may be a useful skill for
players to develop, especially during a congested schedule.
Moreover, nocturnal sleep following a night of partial
sleep loss should also be promoted during several nights.
Sallinen et al. [76] found that, after a night of limited sleep,
14 M. Ne´de´lec et al.
7. an 8-h recovery sleep opportunity the following night
markedly improved both cognitive performance and alert-
ness but did not lead to complete recovery [76]. Finally,
resting periods and sleep-wake schedules are normally
planned for the entire team, regardless of individual dis-
tinctions. Planning individualized schedules based on
players’ preferred sleep schedules may be another effective
countermeasure to restore good sleep [72, 88].
5 Active Recovery
Active recovery, also referred to as ‘cooling down’ or
‘warm down’, is currently performed by 81% of French
professional soccer teams immediately after the match
and/or on the following days. This strategy involves run-
ning, biking or swimming at low intensities for a duration
of 15–30 min. This recovery strategy is often implemented
in professional soccer, as results from numerous studies
[89–94] have reported that active recovery, performed
between 30% and 60% of maximal oxygen consumption
and lasting at least 15 min, enhanced blood lactate removal
or accelerated pH recovery [95, 96] in comparison with
passive recovery. However, lactate removal should not be
the criterion used to test the quality of recovery. Faster
lactate removal does not necessarily involve better per-
formance during subsequent exercise. In several studies
aimed at comparing active and passive recoveries, exercise
performance after active recovery did not improve, despite
lower lactate concentrations [91, 97, 98], while other
studies showed that passive recovery improved perfor-
mance in subsequent exercise [99–103]. Several studies
[95, 104, 105] have reported that active recovery per-
formed immediately after high-intensity exercises signifi-
cantly impaired glycogen synthesis, especially in type I
muscle fibres [95]. According to these results, active
recovery performed immediately after a match does not
present a benefit to implement this technique as part of a
recovery strategy. However, further studies are required to
justify what type of exercise should be performed in the
days following a match.
In a set of studies on recovery between two elite female
soccer matches separated by 3 days, Andersson et al.
[106–108] extensively investigated the effects of 1-h active
recovery (submaximal cycling at 60% heart rate peak and
low-intensity resistance training at 50% one-repetition
maximum) performed at 22 h and 46 h after the first match.
The results showed that active recovery had no effects on
the recovery pattern of physical performance markers (i.e.
countermovement jump, 20 m sprint performance, and
maximal isokinetic knee flexion and extension), perceived
muscle soreness and biochemical markers (i.e. CK, urea
and uric acid) [107]. Andersson et al. [106] did not report
any differences in the pro- or in the anti-inflammatory
cytokine response between the active recovery group and
the passive group. Finally, the active recovery regimen had
no effect on changes in oxidative stress markers and anti-
oxidants [108]. According to these results, implementing
1 h of active recovery during the 3 days following a match
does not seem beneficial, nor detrimental to the outcome of
the recovery process. Further research on exercise mode,
duration and intensity and the time of active recovery is
needed to clarify its interest as a recovery modality.
6 Stretching
Elite soccer teams devote a substantial amount of training
and match preparation time to stretching. Dadebo et al.
[109] reported that the English Premiership clubs allo-
cated almost 40% of total training time to flexibility
training with static stretching, the most popular technique
employed. The Premiership clubs reported a mean static
stretching holding time of 31 s and a mean number of
repetitions per hamstring muscle group of three (range:
2–5) repetitions per session. Stretching exercises are per-
formed for several reasons, including improvement of the
range of motion and the decrement of musculotendinous
stiffness [110, 111] to prevent injury [109, 112, 113], as
well as promoting recovery. In French professional soccer,
50% of teams currently use stretching as a recovery
strategy. However, there is no substantial scientific
evidence to support the use of stretching to enhance the
post-exercise recovery of soccer players [46, 114, 115]. In
a meta-analysis including 12 studies, Herbert et al. [116]
reported that stretching is not clinically worthwhile for
reducing muscle soreness in the days following exercise.
Stretching after eccentric exercise may even hinder the
outcome of the recovery process. Lund et al. [117] sug-
gested that both stretching and eccentric exercise leading
to delayed onset of muscle soreness may affect the muscle
tissue, which may explain the fact that the seven untrained
women in their study showed a greater decrease in con-
centric and eccentric quadriceps strength following both
eccentric exercise and stretching in comparison with
eccentric exercise alone.
7 Compression Garments
Compression garments function by applying a pressure on
the lower extremities in order to increase femoral blood
flow [118]. The principle is to increase the pressure on the
ankle and to decrease it on the mid-thigh in order to
improve the venous return and thus reduce venous stasis in
the lower extremities [118]. This section will only focus on
Soccer Recovery: Part II—Strategies 15
8. the effects of compression garments on the recovery pro-
cess. Compression garments, especially for the lower body,
have recently become increasingly popular amongst
applied soccer practitioners in an attempt to accelerate
recovery from training and competition. Twenty-two per
cent of French professional soccer teams currently inte-
grate compression garments into their recovery protocol.
While studies have shown possible interest in the recovery
of muscle soreness to pre-exercise levels, improvements in
performance measures post-exercise are lacking. No ben-
efits in repeated-sprint performance [119, 120], peak power
output [120], isokinetic strength [121], sprint, agility and
countermovement jump performance [122] have been
reported with regard to the use of compression garments
during the recovery process, although all of these studies
reported subjective feelings of recovery improvement
when using compression garments. As the studies did not
have a placebo condition (i.e. using a garment, but no
compression), a placebo effect due to wearing the garments
should not be excluded [120].
Up until now, studies demonstrating the potential utility
of compression garments for post-exercise recovery have
only addressed their use in elderly athletes [123] or
untrained subjects [124, 125], who are unlikely to closely
reflect the demands of elite soccer. With elderly athletes,
Chatard et al. [123] found that wearing compression gar-
ments during an 80-min recovery period between two
maximal 5-min cycling exercises led to a significant 2.1%
increase in subsequent performance. Gill et al. [126]
reported effects on post-exercise removal of metabolites:
full-leg compression garments, worn for 12 h after a single
rugby match, enhanced CK clearance more than passive
recovery in elite male rugby players. However, the ability
of compression garments to enhance the overall rate of
recovery and especially physical performance after a match
is yet to be demonstrated. Another potential limitation of
studies on compression garments is that the actual pres-
sures applied by the garments to subjects are not measured
[122]. As a consequence, the minimum pressure of
18 mmHg at the ankle and 8 mmHg at the level of the
mid-thigh is not always guaranteed [127]. According to
Montgomery et al. [39] and Davies et al. [122], the level of
compression may be insufficient to have a beneficial
impact following normal exercise (i.e. a team sport com-
petitive match); however, after extreme eccentric exercise,
compression garments may be effective when disruption to
muscle architecture and swelling is more apparent. Trenell
et al. [128] reported that 1 h after eccentric exercise, the
leg wearing a compression garment showed a significant
elevation (p 0.05) in phosphodiester on phosphorus
magnetic resonance spectroscopy spectra relative to the
control leg (no compression). Phosphodiester is represen-
tative of increased skeletal muscle membrane turnover, and
this result suggests an accelerated inflammatory and repair
timeframe induced by compression garments.
In conclusion, the use of compression garments fol-
lowing an elite soccer match may be useful to alleviate
muscle soreness but more research is required to demon-
strate the ergogenic benefits. Compression garments have
no additional benefit in comparison with active recovery
[126], contrast water therapy [126, 129] or massage [125].
As no studies have reported negative effects on exercise
performance, the use of compression garments may pro-
vide an easy-to-use recovery strategy in a team. They could
be useful during air travel, especially during a long flight,
to reduce the risk of deep vein thrombosis [130]. Never-
theless, caution should be taken, as compression garments
may be uncomfortable to wear during the night and are
associated with an increase in body temperature, thereby
disturbing subjects’ patterns of sleep [122].
8 Massage
Massage corresponds to a ‘mechanical manipulation of
body tissues with rhythmical pressure and stroking for the
purpose of promoting health and well-being’ [131]. To
promote recovery after a soccer match, numerous tech-
niques such as effleurage, petrissage, tapotement, friction
and vibration are currently used in 78% of French profes-
sional soccer teams. Effleurage involves light pressure at the
beginning to heavier deeper pressure towards the end and
aims to soothe sore muscles and to relax [132]. Petrissage
involves a kneading motion where tissue is compressed and
lifted away; it aims to loosen muscle spasm [132]. Tapote-
ment consists of repeated rapid hand striking and aims to
stimulate muscle tissues [133]. Friction is short deep
stroking parallel or transversally across the tissue fibre
direction and aims to reduce muscle spasms [132]. Vibration
consists of shaking and aims to facilitate muscle relaxation
[132]. Expected benefits of massage include both physio-
logical and psychological functions. Pulsed Doppler ultra-
sound and echo Doppler have been used to investigate
muscle blood flow and indicated that manual massage—
effleurage, petrissage or tapotement—did not increase blood
flow in small (forearm) or large (quadriceps) muscle mass
[134–136]. No beneficial effect was found for blood lactate
removal [136, 137], H?
removal [136] and neutrophil counts
[138]. Whilst for physiological function, benefits of mas-
sage are still lacking, the scientific evidence supporting their
psychological benefits is substantially greater. Weinberg
et al. [139] observed a positive relationship between mas-
sage and mood state. Two studies [140, 141] found that
massage decreased the subjective symptoms of delayed-
onset muscle soreness. Hemmings et al. [137] investigated
the effect of massage on a measure of perceived recovery
16 M. Ne´de´lec et al.
9. made by the subjects rating their feeling on a 4-item linear
scale (refreshed, recharged, rested and recovered) during the
1-h recovery implemented between two simulated boxing
bouts. The results showed that massage intervention sig-
nificantly increased perceptions of recovery compared with
the passive rest intervention without improving punching
force during the second bout. Similarly, Hilbert et al. [138]
found that the intensity of soreness was significantly lower
(p 0.05) in subjects receiving a massage treatment
(effleurage, tapotement and petrissage) relative to the con-
trol group at 48 h post-exercise. However, no significant
treatment differences for eccentric hamstring peak torque
were reported. This latter result confirms that soreness is
poorly correlated with changes in muscle function, in terms
of both magnitude and time-course after exercise-induced
muscle injury [142]. In terms of performance recovery, most
of the studies failed to find a significant beneficial effect
of massage on subsequent exercise after local exercises
[143–146] or global exercises [92, 147]. It should not be
excluded that massage of injured tissue may lead to further
damage in muscle if given immediately after a training
session that induced muscle damage. Viitasalo et al. [148]
found that CK and myoglobin concentrations were signifi-
cantly higher in elite athletes receiving water massage after
strength/power training sessions than during the control
week. However, results from our survey suggest that water
massage is not a common practice with elite soccer players.
The potential effects of effleurage, petrissage, tapotement,
friction and vibration in further damaging injured tissue
remain, consequently, allusive.
In conclusion, the majority of the evidence points
towards massage being effective in alleviating muscle
soreness and improving perceptions of recovery, although
its effect on muscle function and performance is unclear.
The inconsistency in research findings could be attributed
to the large variety of massage techniques used and the
individual skill of the therapist [149, 150]. Further research
is required to identify the conditions of massage (the type,
duration and period) that produce positive benefits for the
recovery process.
9 Electrical Stimulation
Electrical stimulation is another recovery strategy used by
some professional soccer players (13% of French profes-
sional soccer teams). Electrical stimulation involves the
transmission of electrical impulses via surface electrodes to
peripherally stimulate motor neurons, eliciting muscular
contractions [151]. Many electrical stimulation forms can
be performed according to the frequency, the intensity or
current amplitude, pulse characteristics (the shape and
duration), duty cycle, electrode [152]; but transcutaneous
electrical nerve stimulation [153] and low-frequency
electrical stimulation [154–157] are those most frequently
used for recovery purposes [158]. The effects of electrical
stimulation on the recovery of strength production capacity
and on the reduction of muscle soreness were reviewed by
Babault et al. [158]. Results concerning the benefits of
electrical stimulation using transcutaneous electrical nerve
stimulation or low-frequency electrical stimulation on the
recovery process are equivocal. Among studies reviewed
by Babault et al. [158], 11 of 12 studies failed to find a
significant effect of electrical stimulation on the ability to main-
tain performance after exercise [153–155, 157, 159–161].
Positive effects of low-frequency electrical stimulation were
found for CK clearance [160] and blood lactate removal
[161, 162], with the limits previously evoked for these bio-
chemical markers in the recovery process.
To our knowledge, only two studies on electrical stim-
ulation have been conducted so far in a soccer setting
[156, 163]. In these studies, no main effect of electrical
stimulation was observed on anaerobic performances (i.e.
squat jump, countermovement jump, bounce jumping and
10 m sprint) but electrical stimulation was more beneficial
(p 0.01) than water-aerobic exercises and passive rest for
reducing muscle soreness [156, 163].
In conclusion, although electrical stimulation is often
used for recovery purposes, no scientific evidence exists
regarding its effects to maintain physical performance. The
levels of scientific evidence concerning the decrement of
subjective rating such as muscle soreness are also limited.
10 Conclusion
As mentioned in part I of our review [1], fatigue following a
soccer match is multifactorial and related to dehydration,
glycogen depletion, muscle damage and mental fatigue. A
multitude of recovery strategies are currently implemented
in professional soccer clubs to target these causes of fatigue.
Recovery strategies aimed at reducing acute inflammation
from muscle damage and enhancing its rate of removal are
particularly used in professional soccer settings.
Some strategies such as hydration, diet, sleep and cold
water immersion are effective, with regard to their ability
to counteract the fatigue mechanisms. For dehydration,
Shirreffs et al. [5] recommended consuming a high-sodium
drink (61 mmol/L) equivalent to 150–200% of the sweat
loss after a match inducing moderate dehydration (2% of
body mass). Proteins such as milk should be consumed at
the end of a match or after a training session leading to
muscle damage in order to reduce muscle soreness and to
improve subsequent muscle function. A meal containing
high-GI carbohydrate and protein should be served to the
players within the hour following the match to replenish
Soccer Recovery: Part II—Strategies 17
10. substrate stores and to optimize muscle-damage repair. In
addition, some nutrients containing omega-3 fatty acids
and antioxidants should be included in the daily diet to
reduce potential muscle soreness and attenuate the loss of
muscle force. Sleep is an essential part of recovery man-
agement, as sleep disturbances after a match are common
and can negatively impact on recovery processes. Adequate
sleep allows a reduction in the amplitude of muscle sore-
ness and appears to be an important factor for mental
fatigue. For muscle damage, cold water immersion at a
temperature between 9 °C and 10 °C for 10–20 min seems
useful during acute periods of fixture congestion in order to
regain as quickly as possible the initial level of perfor-
mance and to repress the acute inflammatory process.
Further studies should analyse the effects of these recovery
strategies on central fatigue. Scientific evidence for the
other strategies reviewed, such as active recovery, stretch,
compression garments, massage and electrical stimulation,
is still lacking in the ability to accelerate the return to initial
levels of performance. The lack of evidence, however, does
not mean that these strategies do not aid recovery, but
means that the protocols implemented until now do not
significantly accelerate the return to the initial level of
performance in comparison with a control condition.
Many studies examining the efficacy of recovery strat-
egies have focused on recovery in untrained individuals
from non-soccer-specific exercise and/or recovery proto-
cols that do not closely reflect the physical demands of elite
soccer play. The applicability of these to recovery between
matches for elite soccer players is consequently question-
able and has yet to be shown. Other potential limitations of
studies regarding recovery strategies are that soccer players
may respond differently to recovery strategies if they are
accustomed, or not, to playing several matches during a
congested schedule and the difficulty in implementing a
control condition to prevent any placebo effect (e.g. com-
pression garments).
In the survey on recovery in the professional soccer
teams, practitioners revealed that different recovery strat-
egies are combined in overall recovery protocols. While
the importance of isolating each strategy to determine its
effects in future research remains important, it would also
be interesting to analyse the potential interactions between
the techniques. Longitudinal research protocols should be
led to examine the chronic effects of recovery strategies on
cellular to molecular adaptations. If a robust pro- and anti-
inflammatory cytokine response occurs following a single
elite soccer match, a dampened anti-inflammatory cytokine
response occurs after a second match played within 72 h
[106]. For future studies, it would be rational to determine
when to implement anti- or pro-inflammatory recovery
protocols according to the inflammatory response.
