Objective:To study the effects of fatigue on human stability by comparing the effects of different degrees of fatigue on the dynamic postural stability of the half-squat jump,so as to provide theoretical basis for preventing lower limb injuries.Method:A three-dimensional force measurement platform was used to collect the biomechanical parameters of 20 ordinary male college students who completed the half-squat jump in the state of no fatigue,moderate fatigue and severe fatigue,and SPSS26.0 statistical software was used to perform the one-way variance analysis of repeated measurement for the half-squat jump under different degrees of fatigue.Result:The stability index and dynamic stability index of the half-squat jump in left and right directions,forward and backward directions and the vertical direction were significantly increased in the state of moderate fatigue and severe fatigue (P<0.01),indicating that fatigue would weaken the postural control ability of human body and increasing the risk of lower limb injuries.
