Sex differences in lower landing kinematics through neuromuscular fatigue/Lyties poveikis apatiniu galuniu nusokimo kinematikos rodikliams nuovargio metu

Rapid deceleration during sporting activities, such as landing from a jump, has been identified as a common mechanism of acute knee injury. Jumping and landing activities performed during different phases lead to differences in foot strike knee flexion, as well as peak knee and hip loads. The aim of the study was to evaluate sex differences in landing from a jump in relation to lower extremity landing kinematics through neuromuscular fatigue. The higher indices of female jump height decrease and fatigue when comparing results during 100 jumps were ascertained. Women demonstrated lower peak hip, knee joint angles and lower EMG values in T2 phase when landing from a drop jump. Furthermore, correlations between H, EMG values and landing kinematics were generally higher for women than men.
