Jump Training in Youth Soccer Players: Effects of Haltere Type Handheld Loading
The aim of this study was to compare the effects of a jump training program, with or without haltere type handheld loading, on maximal intensity exercise performance. Youth soccer players (12.1±2.2 y) were assigned to either a jump training group (JG, n=21), a jump training group plus haltere type handheld loading (LJG, n=21), or a control group following only soccer training (CG, n=21). Athletes were evaluated for maximal-intensity performance measures before and after 6 weeks of training, during an in-season training period. The CG achieved a significant change in maximal kicking velocity only (ES=0.11–0.20). Both jump training groups improved in right leg (ES=0.28–0.45) and left leg horizontal countermovement jump with arms (ES=0.32–0.47), horizontal countermovement jump with arms (ES=0.28–0.37), vertical countermovement jump with arms (ES=0.26), 20-cm drop jump reactive strength index (ES=0.20–0.37), and maximal kicking velocity (ES=0.27–0.34). Nevertheless, compared to the CG, only the LJG exhibited greater improvements in all performance tests. Therefore, haltere type handheld loading further enhances performance adaptations during jump training in youth soccer players.
