This study investigated the effects of medical shockwave therapy on muscle activation patterns and performance in healthy athletes. Golfers and weightlifters underwent shockwave therapy targeting specific muscles. Post-treatment, golfers showed increased swing speed, ball distance, and faster muscle activation. Weightlifters showed faster muscle activation but lower energy output during squats, though they were able to lift more weight. The study suggests shockwave therapy may induce favorable biological responses in healthy muscles, reducing fatigue and potential for overuse injuries over time. Further research is warranted.

This study shows that repeated cold-water immersions (4
4 mins at 4-C) cause considerable alterations to muscle behavior. These alter-

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

Post exercise cold water immersion attenuates acute anabolic signallingFernando Farias
these two studies offer new and
important insights into how cold water immersion during
recovery from strength exercise affects chronic training
adaptations and some of the molecular mechanisms that
underpin such adaptations. Cold water immersion delayed
or inhibited satellite cell activity and suppressed the
activation of p70S6K after acute strength exercise. These
effects may have been compounded over time to diminish
the expected increases in muscle mass and strength as a
result of training. The results of these studies challenge the
notion that cold water immersion improves recovery after
exercise. Individuals who use strength training to improve
athletic performance, recover from injury or maintain
their health should therefore reconsider whether to use
cold water immersion as an adjuvant to their training.

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

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.

Experimental Muscle Mechanics in Aging and DiseaseInsideScientific
The focus of this webinar is on the mechanisms underlying muscle impairment associated with aging and age-related diseases. This research evaluates the regulation of muscle contraction at the motor protein, single muscle fiber, and whole muscle levels using in vitro, in situ and in vivo methods in experimental and clinical settings. Specifically, Dr. Qaisar is interested in the contribution(s) of muscle SR stress and calcium dysregulation to loss of muscle mass and strength. Reduced calcium uptake by muscle SR plays a pivotal role in muscle impairment in aging while boosting SR calcium uptake with pharmacological activators can partially restore muscle mass and strength. Matt shares a technical overview of the experimental equipment used in this research. He discusses the design, component functionality, and the applications that can be explored with this system. He also shares some valuable insights into the parameters that can be measured and the data that can be produced with various experimental designs.
Key Learning Objectives
- Contractile dysfunction in sarcopenia involves alterations at motor protein, single fibers and whole muscle levels in rodent models of aging and elderly humans
- Loss of calcium regulation by muscle SR plays a pivotal role in muscle atrophy and weakness associated with sarcopenia
- Age-associated comorbidities such as COPD and Parkinson’s disease accelerated the sarcopenia phenotype in humans
- Circulating biomarkers such as CAF22 can be useful predictors of muscle mass and strength in accelerated sarcopenia
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.
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.

Review of Software to Analyse the Physical Conditions of the Athletes using sEMGijtsrd
Electromyography measures muscle responses of a nerve's simulation of the muscle. EMG is generally measured or recorded through surface, needle or wired electrodes. The surface electromyography is a commonly used technique for measuring the muscle exhilaration. The purpose of this project is to evaluate the use of sEMG in the practical context and to translate the given context to the appropriate analysis. The sEMG are used on the athletes while they are running and respective results are being noted. By using this technique our project wishes to implement an android iOS application to calculate the corresponding values which are being noted by the particular device which we have been made. The signals which are being given by the device is converted into the appropriate percentage values or graphs which can be determined into giving a complete overview about the person whom he is checking and can suggest the diets and exercises to make that person fit to the expectations. This software is mainly look forward for the development of the future athletes which can win the prizes. This platform provides immense forms of diets which are based on the values or results which have been depicted. Performance analysis in sports is considered to be an integral component of understanding the requirements of the optimal performance. Several measurement techniques have been used to inspect the performance of the best athletes today. it is mostly commonly done in laboratory where physiology and bio mechanics can be analyzed. in this system first, the coaches conduct a study about the agility, strength and nutrition of the excellent players of the country. Then the coaches of the respective clubs or the schools check each and every student's physical condition and compare with the stored data in order to train them. The project has got direct advantage to the aspiring future athletes of the country and also to the health conscious society by providing them a device to calculate on their body metrics and work around to improve on it.

Introduction
Over the past decade medical shockwaves have been successfully utilised in sports
medicine in the area of chronic tendinopthies. The stimulus transduction form
medical shockwaves is understood to induce and regulate a favourable biocellular
and molecular response that is seen to ameliorate the aberrances associated with
various pathologies including that of sports injuries.1-10
Our project undertook to
investigate what effects medical shockwaves would have on muscle activation
patterns and its influence on performance in healthy athletes.
Materials and Methods
Amateur right handed elite male athletes from two different sports: Golf (n=4), and
Weightlifting (n=4) were recruited for this project. Baseline and post treatment
measures utilised quantitative instrumentation and subjective feedback. Flight
Scope™ (Golf Technologies USA) recorded golf swing speed, clubface-ball
interface, and ball distance. Back-squat routine was utilised for weightlifting where
each lifter conducted 5 sets of back-squats carrying 120kgs. The personal best (PB)
of each weight lifter for their individual back-squat category was utilised to act as
marker to measure changes from baseline capacity. Muscle activation patterns
assessing onset of muscle activation and energy output in both golf swing and
weightlifting were assessed utilising digital wireless Trigno™ sEMG sensors and
2. data was tabulated utilising EMG Works software (Delsys Inc. USA). Six muscles
were assessed in golf and eight in weightlifting. Post-ESWT assessments were
conducted after a six week interval from the last ESWT session. Medical
shockwaves were propagated by an electrohydraulic generator (CellSonic, Apex
MediTech). 500 acoustic impulses were administered on each muscle over three
sessions at one week intervals.
Results
Flight scope recorded an increase in golf swing speed (baseline avg: 140.21km/h –
post ESWT avg: 147.12km/h [+10.49%]), clubface-ball interface (baseline avg:
1.32m/sec – post ESWT avg 1.46m/sec [+11%]), and ball distance (baseline avg:
143.25m – post ESWT avg: 167.4m [11.6%]) from baseline. Muscle activation
patterns in golf recorded faster muscle activation (baseline avg over 6 muscles x
4golfers: 1.35sec – postESWT avg 0.89sec), and energy output (baseline avg over 6
muscles x 4golfers: 487.44üv/swing – postESWT 575.93üv [+8.46%]) across each
individual from baseline. In weightlifting muscle activation recorded faster onset
patterns (baseline avg over 8 muscles x 4 weightlifters: 1.02sec – postESWT avg
0.92sec) from baseline. However energy output recorded lower output levels during
120kgs back-squat routine (baseline avg over 8 muscles x 4 weightlifters:
1588.08üv/backsquat – post-ESWT 1322.87üv/backsquat [-16.7%]) from baseline.
Personal best of each weightlifter recorded an increase in back-squat lifting capacity
(baseline avg: 655kgs – post-ESWT: 738kgs [11.2%) from baseline.
Discussion
Our project undertook to determine the influence of medical shockwaves on the
activation and performance of muscle tissue in health athletes. Observations utilising
sport specific measurement instrumentation and sEMG suggest that medical
shockwave have a positive influence on muscle activation and energy output
patterns, which in-turn influences performance, and could potentially reduce overuse
and fatigue related pathophysiology. The benefits from ESWT demonstrated a
positive influence six weeks post intervention suggesting a fairly good treatment
outcome survival-curve. Over the past decades medical shockwaves have been
known to promote a positive homeostatic return of several pathologies including
chronic unresponsive sporting injuries. The impact and influence of medical
3. shockwaves on the cellular and molecular signalling and response pathways is yet to
be completely elucidated, however it may be plausible to suggest that medical
shockwaves influence the cellular-matrix through receptors and mechanosensory
substances promoting favourable cellular interaction, communication and integrity.11-
17
This cellular influence from medical shockwaves may be actively reproduced in
healthy subjects. No adverse incidence was reported from this project.
Conclusion
Given the observations of our study it is plausible to suggest that medical
shockwaves may potentially induce and regulate a favourable biocellular and
molecular response in fatigued tissue of healthy athletes offering the potential to
reduce and even prevent overuse syndromes. Further investigation is warranted in
this area.
