Abstract des Autors
The aim of the present study was to observe modifications of the intermuscular coordination pattern, during sprint cycling, under fatigue and training conditions. Ten subjects performed 15 sprints of 5 s duration with 25 s rest between, before and after 9 weeks of training. Surface EMG signals indicated that intermuscular coordination was not significantly modified after sprint cycle training. On the other hand, sprint repetition fatigue induced a delay in the activation phases of power producer muscles. These results tend to demonstrate that power and force gains observed after training are not attributable to coordination improvement. On the contrary, force and power losses observed after fatigue may be partly attributed to neuromuscular pattern modifications. Verf.-Referat
