The effect of 40 m repeated sprint training on physical performance in young elite male soccer players

Serbian Journal of Sports Sciences 09/2012; 6(3):111-116.

ABSTRACT The purpose of this study was to investigate the effect of eight-week repeated sprint training program on maximum sprinting speed, endurance sprinting speed, jump height and the ability to repeat and recover from high-intensity exercise (Yo-Yo IR1). Fifteen young, well-trained, elite male soccer players aged (±SD) 16.3 ±0.5 years, body mass 68.1 ±9.4 kg, and stature 178.5 ±7.3 cm, volunteered to participate in this study. All subjects were tested on 40 m sprint, 10x40 m repeated sprint, 3–6–9 agility with a 180° turn, countermovement jump (CMJ), squat jump (SJ), and Yo-Yo IR1 test. Subjects were randomly assigned to one of two groups: a training group and a control group. The training group followed a repeated sprint training program twice a week. The results indicate significant improvement within the training group from pre-to post-test in 10x40 m repeated sprint time (-0.29 s), 40 m sprint time (-0.33 s), 0–20 m sprint time (-0.19 s), 20–40 m sprint time (-0.15 s) and CMJ (1.3 cm). The control group results showed notable improvements in 0–40 m sprint time (-0.11 s), 10x40 m repeated sprint time (-0.09 s) and 0–20 m sprint time (-0.10 s). A comparison between groups indicates that there were marked differences between the two groups in 40 m sprint time (-0.22 s), 10x40 m repeated sprint time (-0.20 s) and 20–40 m sprint time (-0.15 s). We concluded that repeated sprint ability is trainable and the larger improvement within the training group as compared to the control group could be explained by the extra weekly repeated sprint training.

    ABSTRACT: The purpose of this study was to determine the effects of short-term plyometric training interposed with 24 hours or 48 hours of rest between training sessions on explosive and endurance adaptations in young soccer players. A total of 166 players, between 10 and 17 years of age were randomly divided into 3 groups: control (CG; n=55), plyometric training with 24 h (PT24; n=54), and 48 h (PT48; n=57) of rest between training sessions. Before and after intervention, players were measured in squat jump (SJ), countermovement jump (CMJ), 20 (RSI20) cm drop jump reactive strength index, broad long jump (BLJ), 20-m sprint time, 10 x 5-m agility time, 20-m multi-stage shuttle run test (MST), and sit and reach test (SR). The plyometric training program was applied during 6 weeks, 2 sessions per week, with a load from 140 to 260 jumps per session, replacing some soccer-specific drills. After intervention, the CG did not show significant performance changes. PT24 and PT48 groups showed a small to moderate significant improvement in all performance tests (p<0.001), with no differences between treatments. Although it has been recommended that plyometric drills should not be conducted on consecutive days, the study shows that plyometric training applied twice weekly on consecutive or non-consecutive days result in similar explosive and endurance adaptations in young male soccer players.
