Biomechanical analysis of long pass in U-۱۹ women football players

Kicking movement is process of moving position on leg. Biomechanical analysis explains kick performance which influenced by kinematics and kinetics factors. The research purpose analyzed biomechanical long pass movement. This research is both qualitative and quantitative. The research sample are ۱۱ Indonesian woman football players who were taken by saturated sampling. Data in the form of long pass kick video with airborne ball test. Data analyzing used Kinovea software to determine the flexion angle of backswing kick leg, hip angle, and distance to target, then looking for the force, power, and energy in kick motion. The motion analysis shown that sample ۳ produces closest distance to target as far as ۰.۶۵ m which done with flexion angle of backswing knee is ۷۴۰ and hip angle of ۶۴۰. The force exerted by sample ۳ is ۱۰.۰۹ N, resulting in a ball speed of ۲۲.۴۲ m/s and a kinetic energy of ۱۱۳.۱۲ Joule, potential energy of ۱۴.۶۴ Joule and mechanical energy of ۱۲۷.۷۶ Joule. It can be concluded that accuracy of long pass kick are influenced by flexion angle of backswing kick knee, hip angle, power and force as well as producing energy in the form of kinetic, potential, and mechanical energy.
