The effect of 8 weeks repeated sprint training program on maximum sprinting speed, endurance running speed, jump height

Formal

The purpose of this study was to investigate the effect of 8 weeks repeated sprint training program on maximum sprinting speed, endurance running speed, jump height and the ability to repeat and recover from high-intensity exercise (Yo-Yo IR1).

Description

Fifteen young, well-trained elite males’ 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 participants were tested on 40m sprint, 10x40m repeated sprint, 3-6-9 agility with 180 ° turn, Counter Movement Jump (CMJ), Squat Jump (SJ) and Yo-Yo IR1-test. Participants were matched according to their pre-test results from 0-40m sprint time (s).

 

Then they were randomly assigned into one of two groups, a training group (TG) (n=8) and a control group (CG) (n=7). The training group followed a repeated sprint training program twice a week. The training program consisted of sprinting 4 sets of 5x40m with 90s recovery between repetitions and 10min recovery between sets.

Result

The results indicate a significant improvement within TG from pre to post-test on 40m sprint time (-0.33s), 10x40m repeated sprint time (-0.29s), 0-20m sprint time (-0.19s), 20-40m sprint time (-0.15s) and CMJ (1.3cm). The within CG results showed a notable improvement on 0-40m sprint time (-0.11s), 10x40m repeated sprint time (-0.09s) and 0-20m sprint time (-0.10s).
 
A comparison between groups indicates that there were marked differences between the two groups at 40m sprint time (-0.22s), 10x40m repeated sprint time (-0.20s) and 20-40m sprint time (-0.15s). We concluded that this type of training was effective for the soccer players in this study and the larger improvement within TG compared to CG could be explained by the weekly extra repeated sprint training.
