Different Biomechanics in Football Shooting Using Inside and Instep Kick
Abstract
This research purposes were examinedthe differences in shooting accuracy using inside and instep kicks and observe differences in kick movements based on biomechanical variables. Twelve professional football players shot using inside and instep kicks on circular hops targets, shooting motions were recorded using a camera at 1000 frames per second. The kinematics during the swing phase and the impact phase with the ball producing the ball’s trajectory were analyzed. Independent t-test used to compare shooting using inside and instep kick. The results showed that there was a significant difference in shooting accuracy using inside and instep kick (tcount = 3.317, p = 0.003) with a effect size large (Cohen’s d = 1.35). When observing the movements, there were significant differences in backswing knee angle (p=0.024), frontswing knee angle (p=0.034), shoulder tilt angle (p=0.045), ball bearing foot placement (p=0.019), and inclination angle of pedestal foot(p = 0.000), while other biomechanical variables showed no significant difference (p > 0.05). This research concludes that accurate shooting movement is achieved using inside kicks, caused by the backswing and frontswing knee angles, body tilt, and the placement and angle of the pedestal foot.
