KINEMATIC ANALYSIS ON THE PUNT KICK IN FOOTBALL GOALKEEPER

Abstract

The present study aimed to investigate punt kicks by football goalkeepers on the basis of differences in the effort of the kick. Twelve experienced goalkeepers participated in the study. The participants were made aware that for the maximum distance trial (the 100% trial), they should send the ball as far as possible, and for the 80% and 60% trials they should have a more controlled approach. Punt kicks were divided into three phases: the phase of release of the ball from the left hand (BR), the phase of pivot foot ground-contact (LFC), and the phase of the ball impact (IMP). Right hip and knee joint angles were calculated. In comparison to lower intensity punt kicks, the higher effort punt kicks involved increasing the hip joint extension angle for the right foot during the backswing and lowering the knee joint angle of the right leg at the start of the forward swing, thereby producing forward swing velocity for the right foot.
