The purpose of this study was to examine the selective influences maximum acceleration capability on change direction (COD) speed, COD deficit, linear sprint momentum, and loaded unloaded vertical jump performances in forty-nine male professional soccer players (24.3 ± 4.2 years; 75.4 5.4 kg; 177.9 6.4 cm). Soccer performed assessments following order: 1) squat countermovement jumps; 2) 20-m sprinting speed test; 3) Zigzag ability 4) bar-power outputs exercise. Athletes were divided, using a...
ABSTRACT Sprinting is a key component for many individual and team sports. Therefore, to enhance sprint performance, various training methods are widely used by coaches practitioners, including maximum speed resisted training. Resisted sprinting with sled towing method that has recently received considerable attention from the sport science community. However, date, no consensus exists regarding its acute chronic effects in athletes. This narrative review aimed (a) analyze mechanics of under...

Olympic coaches are likely to have adequate knowledge and implement effective training programs. This study aimed describe critically examine the strength conditioning practices adopted by Brazilian sprint jump coaches. Nineteen (age: 50.2 ± 10.8 years; professional experience: 25.9 13.1 years) completed a survey consisting of eight sections: 1) background information; 2) strength-power development; 3) speed training; 4) plyometrics; 5) flexibility 6) physical testing; 7) technology use; 8)...
This study investigated the effects on neuromuscular performance of a 6-week Optimal Load Training (OLT) and novel modified Complex (MCT) (complex pairs: same exercise using moderate an OL) in basketball players, in-season. Eighteen male athletes were randomly assigned to one protocols. Anthropometric measurements taken evaluate body composition. Lower- upper-body maximum dynamic strength, countermovement jump (CMJ), standing long (SLJ), 10-m sprint change direction (COD) also assessed....
Abstract The aim of the present study was to investigate influence maximum strength and power levels on change direction (COD) ability deficit in elite soccer rugby players. Seventy-eight athletes (soccer, n = 46; rugby, 32) performed following assessments: squat countermovement jumps (SJ CMJ), 1 repetition-maximum half-squat exercise (HS 1RM), peak (PP) jump-squat exercise, 20-m linear sprint Zigzag COD tests. Utilizing median split analysis, were divided into two groups according their HS...

Brazil is the leading global exporter of soccer players, with approximately 2,000 international transfers to different clubs per year. Although Brazilian players compete in most prestigious leagues worldwide, habitual training methods, strategies, and routines strength conditioning coaches (SCCs) are undocumented. This study used a standard online survey collect characterize practices SCCs. Forty-nine SCCs (age: 40.4 ± 7.5 years; professional experience: 15.3 years) working teams...
To test the relationships between maximum and relative strength (MS RS), absolute peak force (PF RPF), deficit (SDef), with sprint jump performance, to compare these mechanical variables elite sprinters professional rugby union players.Thirty-five male players 30 performed vertical jumps, 30-m sprint, half-squat 1-repetition (1RM), where force-related parameters were collected. Pearson correlation coefficients used variables. An independent t magnitude-based inferences compared...
The Argentine Rugby Union is a top-tier rugby nation (ranked 8th according to World Rugby), with the Buenos Aires being largest competitive league. To date, training practices of Argentinian strength and conditioning coaches have not yet been documented analyzed. We used an online survey characterize testing strategies commonly implemented by coaches, which could serve as guideline for coaching education programs. Thirty-five (age: 42.0 ± 8.9 years; professional experience: 16.8 8.3 years)...
Hamstring injuries in soccer continue to be a challenge for professionals who work with players daily. Although its origin is multifactorial, the proper management of neuromuscular fatigue during training microcycle very important factor consider. There are no clear guidelines regarding weekly distribution certain exercises that demand hamstrings. The main objective this study was describe usual practices professional European teams. An international observational survey design applied some...
This study aimed to compare: 1) the effects of a 4-week unresisted vs. resisted sprint training programs (UST and RST with 50% body mass, respectively) on both performance; 2) these schemes various strength-power measures (i.e., one-repetition maximum [1RM] isometric squat test (ISqT), eccentric hamstring strength in Nordic exercise [NHE], vertical horizontal jump distances). Thirty-five under-19 male academy rugby players participated were randomly assigned one two groups. Players' (50% BM)...
The aims of this study were to analyze (1) the external match demands during a congested period (CP) (i.e., three games in eight days) and (2) differences among with two- or three-day intervals professional futsal players. Eleven elite male players monitored 15 official matches. Wearable accelerometers used record player load (PL), accelerations (ACC), decelerations (DEC), changes direction (COD) at different intensities (e.g., high, medium, low) using two approaches absolute relative per...

J Strength Cond Res XX(X): 000-000, 2024-Despite various proposed prevention strategies, the incidence of hamstring injuries modern soccer is still elevated. Recent research has focused on exploring how tissue behaves under fatigue conditions as a potential risk factor. This study aimed to...
This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), countermovement (CMJ) tests pre post four weeks training. Athletes were pair-matched groups according their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at load 20%...
The aim of this study was to investigate the change direction (COD) ability and deficits elite rugby union players, discriminating between position (backs forwards), “faster slower players”, in multiple COD tasks. Twenty-four male players from Brazilian senior National team completed following assessments: Squat countermovement jumps; drop jump; standing long jump, horizontal triple 40-m linear sprint; Pro-agility, L-Drill, Zig-zag tests; squat 1-repetition maximum. differences backs...
