IMPORTANCE DE LA PLIOMETRIE DANS LA PREPARATION PHYSIQUE DES JEUNES JOUEUSES EN FOOTBALL FEMININ (14-17 ANS)

Abstract

The pliometry is among the contraction regimes that produces a greater gain of strength in muscle spots according to the literature. The latter boomed with the beginning of the 80s especially in Italy, Bosco and his collaborators (1979)as well as G. Cometti marked history with their experiments in this domain Football is a team sport the most demanding in terms of physical preparation of players and their ability to master the techniques authorized, whether in defense or in attack, and in goal, especially in the control high balls, which depends on the upgrade of relaxation and explosive strength of the lower limbs, which are also based on the vertical jump the maximum of what can be. In fact, there is a lack of training programs for the development of the vertical jump in women's football, and this is the result of a lack of knowledge of trainers, resources and training programs. As known plyometric training is the muscle's ability to stretch and shortening whose objective is to develop a greater force in the shortest time possible production because they impoverished the time of contact of the feet ground in the contraction of antagonistic muscles. (Tahir, 2007). Many trainers and teachers in the field of sport do not realize what the real meaning of plyometric training, despite its great importance that specialists in the field of sports training proved. This prompted us to ask the following questions: - Is this-that the plyometric training has an impact on improving the vertical jump among football players of Afak Relizane (14-17ans)?
