This study examined the relationship between work load indicators used to quantify full training sessions in soccer. The participants were 28 semiprofessional male soccer players age 22.9 ± 4.2 years, height 177 5 cm, body mass 73.6 4.4 kg. Players' physical and physiological was monitored over 44 using global positioning system devices (10 Hz) heart rate, respectively. After each session, players' perceived-exertion (rating of perceived exertion [RPE]) assessed Borg CR-10 scale. internal...

Recent player tracking technology provides new information about basketball game performance. The aim of this study was to (i) compare the performances all-star and non players from National Basketball Association (NBA), (ii) describe different performance profiles based on roles. Archival data were obtained all 2013-2014 regular season games (n = 1230). variables analyzed included points per game, minutes played actions recorded by system. To accomplish first aim, minute play using a...

Completing a marathon is one of the most challenging sports activities, yet source running fatigue during this event not completely understood. The aim investigation was to determine cause(s) in warm weather.We recruited 40 amateur runners (34 men and 6 women) for study. Before race, body core temperature, mass, leg muscle power output countermovement jump, blood samples were obtained. During (27 °C; 27% relative humidity) measured as pace reduction from first 5-km end race. Within 3 min...

Talent identification and development in soccer is often biased by maturation-related differences of young athletes. However, there no information available about success rates for youth maturing at different tempos to achieve elite adult soccer. The purposes this study were determine the prevalence maturational groups among boys playing soccer, track them competence performance. A prospective cohort design was used follow 55, 14-year-old Serbian Division I over eight years. At age 14,...

Background: Soccer presents physiological, metabolic, physical and psychological demands which can deteriorate players’ performance due to fatigue. The high variability in responses also influences the magnitude of exercise-induced muscle damage, with symptoms negatively affecting neuromuscular function during recovery or subsequent training sessions matches. Consequently, more precise consistent knowledge is required this area optimize performance. Objective: Therefore, purpose sum - up...

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....
