Effects Of A Potentiation Method Of Resisted Sled Sprint Training On Mechanical Sprint Performance In Young Soccer Players

Résumé

Resisted Sled sprint training has been shown to improve sprint perfomance. Our study compares the effects of two resisted sled training, with a weight equal to 15% of the subject's mass, on the mechanical sprint perfomance (F0 , V0 , time performance) in young soccer players (N=16). The acceleration and speed of the players was analyzed before and after the training program, after the pre-test the players were randomly divided into three groups, a control group (C), a group who performing a combined training (resisted sled sprint + sprint unloded) (C+S) or who performing a training with resisted sled sprint only (CH). Each group performed two sprints trainings per week during four weeks. After the training programs, the C+S and CH groups had significant improved in time performance of the 0-30 m : 4.70±0.16 to 4.55±0.09 seconds (p=0.02) and 5.11±0.28 to 4.92±0.24 seconds (p=0.04) respectively. A little higher improved was observed for the CH group (3.71% versus 3.19%). The CH group also had a significant gain over 0-20 m : 3.75±0.23 to 3.58±0.18 seconds (p=0.04). In conclusion, the training method with sled training only seems to allow better enhancements for 30 m but also gains for 20 m.
