Effects of 10-week soccer training program on anthropometric, psychological, technical skills and specific performance parameters in youth soccer players

摘要

Summary Objectives. -To verify the influence of 10-week soccer training program on anthropometric, psychological, technical skills and specific performance parameters in youth players. Equipment and methods. -Thirteen young athletes were evaluated two times along the experiment (i.e. in T1, and T2). On the first day, anthropometric evaluation, sexual maturity status, flexibility and psychological parameters were assessed. On the second day, soccer technique tests were performed with 30min of passive recovery in between. On the third day, the sprint tests (i.e. 10, 20 and 50 m) were measured. Finally, the lactate minimum test was performed on the fourth day. Results. -Independently from sexual maturity status changes, a 10-week soccer training program with similar characteristics of volume and intensity may lead to significant changes (P<0.05) in the body mass, body mass index, lean body mass, total mood disturbance, flexibility, slalom dribble and lob pass tests, 30- and 50-m time-trial performances, running intensity at the lactate minimum test and anaerobic parameters of the Running Anaerobic Sprint Test (RAST). In conclusion, based on the importance of soccer technique tests to talent identification, soccer coaches should use this type of evaluation during training routine. 1. Introduction During a soccer match, more than 90% of the effort is sustained by aerobic metabolism where the players run approximately 10 km in average intensity of the anaerobic threshold . According to Stroyer et al. , the actions performed during a match for young soccer players can be classified as: 3.1% standing, 53.8% walking, 34.0% running in low intensity and 9.0% running in high intensity. Although the main physiological metabolic functions in a soccer game are sustained by aerobic metabolism, the most decisive skills, such as jumping, kicking and tackling, are anaerobic . Many studies have been conducted to determine the physiological demands imposed by a soccer match to the players [ and their responses to training programs with youth soccer players. Beyond physiological demands, in studies with young athletes is extremely important to evaluate the specific soccer skills since these parameters are fundamental to talent identification . Although the relationship between maturation and soccer skills has been well reported in the literature , studies about training effects on soccer skills with youth athletes are scarce.
