Relation entre la puissance et la raideur musculotendineuse chez les sportifs de haut niveau athletes

Goal: The aim of this study was to test the relation between the reactive power and the stiffness of the legs in high trained athletes (sprinters and skiing racers). Method: A simple method to measure, in field conditions, the leg stiffness during maximal bouncing was used on twenty-eight sprinters,...

Description
Summary:Goal: The aim of this study was to test the relation between the reactive power and the stiffness of the legs in high trained athletes (sprinters and skiing racers). Method: A simple method to measure, in field conditions, the leg stiffness during maximal bouncing was used on twenty-eight sprinters, and twenty-nine skiing racers. In addition, the mechanical power called reactive power was calculated according to the method proposed by Bosco. The relationship between stiffness and power was observed in the different groups. Results: The value of stiffness obtained was 29,866+/-7372 N.m super(-) super(1). The power was equal to 52.33+/-8,72 W.kg super(-) super(1). The main result of this study was that a relation between stiffness and power was obtained only in the sprinters (r super(2)=0,68, P
