Résumé

The aim of this study is to define the nature of the correlation between some biomechanical variables of the impact phase (foot/ball) affecting the accuracy of the direct free kick in football, by hypothesizing that there is a statistically significant correlation between these variables. The sample consists of five (5) senior semi-professional players (Age: 22.8 ± 2.59 years, Experience: 12.4 ± 1.86 years, Weight: 67.8 ± 4.27 Kg, Height: 1.75 ± 0.04 m). The data collection instrument is an accuracy test of direct free kick shot on three (03) different positions (Right, Centre, and Left) over a distance of 20 m. The results revealed that there, was a statistically significant correlation between the accuracy of the direct free kick, and the velocity of the foot and the ball at the significance threshold p<0.05, the momentum and kinetic energy of the foot have positive correlations at the significance threshold p<0.05, and the momentum and kinetic energy of the ball have negative correlations at the significance threshold p<0.05.
