EFFECTS OF LANDING HEIGHT AND KNEE JOINT MUSCLE FATIGUE ON ANKLE AND KNEE JOINT KINEMATICS DURING CUTTING AFTER LANDING

Abstract

This study aimed to investigate the effects of landing height and knee joint muscle fatigue on ankle and knee joint kinematics during cutting after landing. Participants included 29 adults (age = 20.83 ± 1.56 years; height = 172.42 ± 9.51 cm; mass = 65.07 ± 10.18 kg) with no orthopedic history in the lower limb joints in the previous 6 months. The results showed that different landing heights of 30 and 40 cm and 30% fatigue of the peak torque of knee extensor found a forefoot landing and stiff landing strategy, when cutting after landing. These results might be due to a decline in the shock absorption capability of the knee joint and the movement capability related to cutting while increasing the contribution of the ankle joint.
