Lower limbs asymmetries in the agility and explosive strength in male football players

Abstract

Background: Material and methods: Results: Conclusions: ‪Football game requires a permanent dynamic, in which players frequently perform changes of direction, with or without the ball. This requires explosive strength in the lower limbs as well as agility. The aim of the study was to measure the execution time within the changes of direction over different distances. ‪A total of 20 male football players were selected (aged 17.6±1.27 years old), BMI 21.4 ± 1.99. For the explosive strength, two tests using Optojump (Microgate) were applied: CMJ and 5 jumps single leg left/right front/back drift. Each player also performed an agility test consisting of a single change of direction to the left and another one to the right, then a complete turn with three changes of direction, once to the left and once to the right. ‪Regardless of the dominant part, in the simple agility test there were no significant differences between the left and right leg (p> 0.05), while in the multiple tests, these differences became significant, with a delay in execution on the left side (p<0.05). Also, a moderate correlation was found between explosive strength and agility (r=.544, p
