Sports participation in youth is on the rise (35). In addi-
tion, paradigms in preventive health care are shifting focus
to the benefits of exercise in the aging population, leading
to exercise prescriptions for a previously sedentary group
(14,23,36). As more individuals become active, the number
of exercise-related injuries and conditions such as delayed-
onset muscle soreness (DOMS) is likely increasing (10).
DOMS can limit physical activity or result in pain that de-
ters individuals from continuing their exercise regimen (10).
Whether the athlete is young or old, novice or elite, regular
and/or strenuous exercise can result in DOMS and forma-
tion of fibrous tissue adhesions, leading to decreased range
of motion (ROM) (4,10,15).

Does static stretching reduce maximal muscle performance?Fernando Farias

the effects of static stretching on mus-

with longer stretches.
The use of stretching in the training programs of recrea-

has been debated (49). The purpose of this review was to
examine the literature regarding the effect of stretching on
performance, without regard to any of the other purported
effects of stretching, including improvements in joint range
of motion, muscle length, or recovery from or susceptibility

Anterior Cruciate Ligament Injury: Identification of Risk Factors and Prevent...Fernando Farias
Injury to the anterior cruciate ligament (ACL) is common and affects
young individuals, particularly girls, who are active in sports that involve
jumping, pivoting, as well as change of direction. ACL injury is associ-
ated with potential long-term complications including reduction in ac-
tivity levels and osteoarthritis. Multiple intrinsic and extrinsic risk factors
have been identified, which include anatomic variations, neuromuscular
deficits, biomechanical abnormalities, playing environment, and hormonal
status. Multicomponent prevention programs have been shown to be ef-
fective in reducing the incidence of this injury in both girls and boys. Pro-
grams should include a combination of strengthening, stretching, aerobic
conditioning, plyometrics, proprioceptive and balance training, as well as
education and feedback regarding body mechanics and proper landing
pattern. Preventive programs should be implemented at least 6 wk prior to
competition, followed by a maintenance program during the season.

After an intense bout of exercise, foam rolling is
thought to alleviate muscle fatigue and soreness (ie, delayed-

mance. Potentially, foam rolling may be an effective therapeutic
modality to reduce DOMS while enhancing the recovery of
muscular performance.
F
oam rollers and massage sticks have increased in popularity
in the fitness industry and are often recommended by
strength and conditioning professionals (5,6,10). There is
evidence that shows positive effects of foam rolling on range of
motion (ROM), recovery, and performance (8,9,10,14). Despite its
effectiveness, the mechanisms as to how foam rolling works are
not fully understood. However, it is likely that acute responses in
foam rolling are similar to those elicited by manual therapy, which
are thought to be neurophysiological in origin .

stride cycle may be when the biarticular hamstrings are at greatest injury risk. On this basis, hamstring injury prevention or rehabilitation
programs should preferentially target strengthening exercises that involve eccentric contractions performed with high loads at longer
musculotendon lengths.

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.

A general 10-week IT program utilizing Swiss balls and body mass as a resistance proved effective for improving knee proprioception as well as trunk flexion and extension strength in previously inactive individuals. The present study demonstrates that the use of body weight as a resis- tance under unstable conditions can provide significant improvements in knee proprioception (for as long as 9 months after training) and trunk strength for the untrained population that should contribute to general health and functionality.
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.
Muscular strength, functional performances and injury risk in professional an...Fernando Farias
Muscle strength and anaerobic power of the lower extre-
mities are neuromuscular variables that influence perfor-
mance in many sports activities, including soccer. Despite
frequent contradictions in the literature, it may be assumed
that muscle strength and balance play a key role in targeted
acute muscle injuries. The purpose of the present study was
to provide and compare pre-season muscular strength and
power profiles in professional and junior elite soccer players
throughout the developmental years of 15–21.
Eccentric training using external loads greater than the
relative concentric training intensity is a potent stimulus for
enhancements in muscle mechanical function, and MTU
morphological and architectural adaptations. The inclusion
of eccentric loads above maximal concentric strength is
therefore an avenue to induce novel training stimuli and
effect change in key determinants, and functional metrics,
of strength, power and speed performance. Strength
improvements are largely mode-specific and arise from a
combination of neural, morphological and architectural
adaptations [8]. Increased agonist volitional drive is posited
as the primary contributing factor to the marked increases
in eccentric strength observed following training [54].
Eccentric training improves concentric muscle power and
SSC performance to a greater extent than concentric or
traditional modalities
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,
Hawkins, Hulse, & Hodson, 2002). b
O
vertraining remains one the most controversial topics
within the field of strength and conditioning, as it accounts
for increased fatigue and can result in performance
impairment. One of the many topics that persists among strength
and conditioning professionals is the topic of overtraining. A
common question that is asked is how does overtraining differ
from overreaching? Additionally, some may even question the
very existence of overtraining. Although the prevalence of
overtraining varies considerably among a variety of sports,
the overall occurrence of actual overtraining seen in normal
day-to-day resistance trained individuals is very low (11,17,22).
The purpose of this article is to address the implications of
overtraining and overreaching, the recovery process, signs
and symptoms of overtraining, how resistance training and
supplementation can affect these outcomes, and future directions
within the topic of overtraining.
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.
Short inter-set rest blunts resistance exercise-inducedFernando Farias
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.

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.
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.
Effects of Velocity Loss During Resistance Training on Performance in Profess...Fernando Farias
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).
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)

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)

The purpose of this investigation is comparing the effects of three admitting models using maximum admits in increasing the maximum strength and hypertrophy of unexercised men in the muscles of arm forth. Statistical sample of this investigation are 45 non-athlete male students of Mazandaran University of Science and Technology of the Department of Public Physical Education. Maximum strength and the mass of muscles in the sample was measured using the maximum repeating test in moving arm form by Haler or measured using the arm, before and after the match. Then, the samples were grouped in 3 empirical groups (15 per groups). They exercised for 8 weeks, 3 sessions per week, and 75 minutes per session. The data were analyzed by variance and (LSD) by using SPSS20 software (p≤0.05). There was no meaningful difference among 3 models; normally pyramidal, Counter-pyramidal, and Flat-pyramidal in increasing the shape of arm forth. Also, there was a meaningful difference between two methods, pyramids and flat pyramid after the test. There was no meaningful difference among the methods between counter-pyramidal and flat-pyramidal. So, we can suggest that when the purpose is increasing the muscle, we can use every method, but if the purpose is increasing the strength, it is preferring to use flat pyramidal method.
To Compare The Effect Of Proprioceptive Neuromuscular Facilitation and Static...ijtsrd
Background: Flexibility is an important physiological component of physical fitness and reduced flexibility can cause inefficiency in the workplace and is also a risk factor for low back pain. Increasing hamstring flexibility was reported to be an effective method for increasing hamstring muscle performance.Objective: To compare the effects of modified hold-relax proprioceptive neuromuscular facilitation stretching technique and static stretching on flexibility of hamstring muscle.Materials and Methods: In this comparative study 60 subjects were selected by convenience sampling and research design was comparative and experiment in nature. Subjects were selected on the basis of inclusion criteria. Subjects were divided into two groups, group A and group B allocating alternate subjects to group A and group B, 30 in each group. Group A was treated with Proprioceptive Neuromuscular Facilitation with cryotherapy and Group B was treated with Static Stretching with cryotherapy. Baseline assessment was taken on pre stretch, post stretch and after 24 hours using Active Knee Extension test and Modified back saver sit and reach test.Results: Both the groups showed significant improvement in hamstring flexibility. (p0.05).Conclusion: Thus we concluded that the Proprioceptive Neuromuscular Facilitation Stretching Technique and Static Stretching both are effective to improve flexibility of hamstring muscle and clinically both the interventions are equally effective.

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

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.

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.
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.
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
interspersed by 3 days and complete physical performance recovery may not
be achieved. Incomplete recovery might result in underperformance and in-
jury. During congested schedules, recovery strategies are therefore required
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-
formance (sprints, jumps, maximal strength and technical skills), cognitive,
subjective and biochemical markers.
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
No sentido de melhor esclarecer esta forma de operacionalizar o processo

Impact of the Nordic hamstring and hip extension exercises on hamstring archi...Fernando Farias
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.
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.
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 quadriceps femoris is traditionally described as a muscle group com-
posed of the rectus femoris and the three vasti. However, clinical experience
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
tensor VI (TVI). The aim of this study was to clarify whether this intervening
muscle was a variation of the VL or the VI, or a separate head of the exten-
sor apparatus. Twenty-six cadaveric lower limbs were investigated...
Nossos dados sugerem que um macrociclo com ênfase na capacidade técnica e tática foi capaz de promover aumentos no desempenho físico e tático de jovens jogadores de futebol em situações reais de disputa. Assim, a distribuição das cargas de treinamento utilizadas neste estudo, além de possibilitar uma formação mais específica e contextual, proporcionou um aumento da intensidade do jogo no final da temporada, variável diretamente relacionada ao resultado do jogo (17). Além disso, verificou-se que o protocolo de treinamento causou reduções nos marcadores de danos musculares, revelando um estímulo benéfico para o sistema muscular, o que pode contribuir para a prevenção de lesões por sobreentrenamento ao longo da temporada. Apesar da importância bem documentada da avaliação de parâmetros sangüíneos (ie, marcadores de dano) durante a prática de futebol (3, 4, 23, 29), verificamos que a redução relacionada foi associada com maior taxa de trabalho durante o jogo, Através de um treinamento técnico-tático de periodização, mostrando a importância do monitoramento desses parâmetros em longo prazo.
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
characteristics, and to compare the vertical ground reaction force characteristics of the impulse and landing
phase of a vertical jump between the dominant and non-dominant leg in soccer players.
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.

Narrated Business Proposal for the Philadelphia Eaglescamrynascott12
Slide 1:
Welcome, and thank you for joining me today. We will explore a strategic proposal to enhance parking and traffic management at Lincoln Financial Field, aiming to improve the overall fan experience and operational efficiency. This comprehensive plan addresses existing challenges and leverages innovative solutions to create a smoother and more enjoyable experience for our fans.
Slide 2:
Picture this: It’s a crisp fall afternoon, driving towards Lincoln Financial Field. The atmosphere is electric—tailgaters grilling, fans in Eagles jerseys creating a sea of green and white. The air buzzes with camaraderie and anticipation. You park, join the throng, and make your way to your seat. The stadium roars as the Eagles take the field, sending chills down your spine. Each play is a thrilling dance of strategy and skill. This is what being an Eagles fan is all about—the joy, the pride, and the shared experience.
Slide 3:
But now, the day is marred by frustration. The excitement wanes as you struggle to find a parking spot. The congestion is overwhelming, and tempers flare. The delays mean you miss the pre-game excitement, the tailgate camaraderie, and even the opening kick-off. After the game, the joy of victory or the shared solace of defeat is overshadowed by the stress of navigating out of the parking lot. The gridlock, honking horns, and endless waiting drain the energy and joy from what should have been an unforgettable experience.
Our proposal aims to eliminate these frustrations, ensuring that from arrival to departure, your experience is extraordinary. Efficient parking and smooth traffic flow are key to maintaining the high spirits and excitement that make game days special.
Slide 4:
The Philadelphia Eagles are not just a premier NFL team; they are an integral part of the community, hosting games, concerts, and various events at Lincoln Financial Field. Our state-of-the-art stadium is designed to provide a world-class experience for every attendee. Whether it's the thrill of game day, the excitement of a live concert, or the camaraderie of community events, we pride ourselves on delivering a fan-first experience and maintaining operational excellence across all our activities. Our commitment to our fans and community is unwavering, and we continuously strive to enhance every aspect of their experience, ensuring they leave with unforgettable memories.
Slide 5:
Recent trends show an increasing demand for efficient event logistics. Our customer feedback has consistently highlighted frustrations with parking and traffic. Surveys indicate that a significant number of fans are dissatisfied with the current parking situation. Comparisons with other venues like Citizens Bank Park and Wells Fargo Center reveal that we lag in terms of parking efficiency and convenience. These insights underscore the urgent need for innovation to meet and exceed fan expectations.
Slide 6:
As we delve into the intricacies of our operations, one glaring issue emer
