Effect of some Biomechanical Variables of The Lower Limbs on Long Passes accuracy for Soccer Players

Abstract

The research aims to know the effect of some biomechanical variables of the lower limbs in long passes accuracy for young soccer players. The researcher used the descriptive-analytical correlations method ,that suits the nature and goals of the research. The sample consisted of (20) players of the young category in one of the sports clubs, they were selected by Deliberate method. The researcher chosed Lough borough Soccer Passing Test (LSPT) to measure the long passes accuracy, and measured the biomechanical variables of the lower limbs at the moment of touching the ball by using two-dimensional kinetic analysis (2D) by Kinovea application, and these variables represented the angle of the hip joint, the angle of the knee joint of kicking leg and supporting leg, and torso lean. The results of the research showed significant effect for the biomechanical variables of the lower limbs on long passes accuracy, and also showed that some of these variables contributes more than others to improve the performance accuracy The results confirmed the importance of motor co-ordination between the lower limbs joints, and the role of the supporting leg and torso lean to achievement balance and controlling the path of the ball during the long passing skill as well. The researcher concluded that improving the biomechanical values of the lower limbs effectively contributes to rise the level of long passes accuracy of young soccer players. The research recommended to pay attention to the biomechanical aspect during training, and to adopt kinesthetic analysis to evaluate and correct the performance skill.
