LOWER EXTREMITY STIFFNESS DURING SEPAKTAKRAW SPIKE LANDINGS

Abstract

Sepaktakraw spike landing is the aggressive skill that leads to many injury of lower extremity. Leg and knee joint stiffness is the important factor of sepaktakraw spike injury particularly when landing. The purpose of this study was to investigate lower extremity stiffness of sepaktakraw spike landings. Results showed that leg stiffness and knee joint stiffness of roll spike (RS) during landing was significant higher than half roll spike (HRS). These indicate that RS can -use a high risk of injury due to greater lower extremity stiffness than HRS. Thus sepaktakraw players need to have a good strength and flexibility of muscle to prevent potential risk of lower extremity injury during sepaktakraw spike landings.
