摘要
目的:探讨向心/离心两种不同工作形式引发的肌肉疲劳对踝关节本体感觉及人体站立平衡能力的影响。方法:选取健康男性大学生受试者40名,随机分为向心疲劳组和离心疲劳组,每组20名,分别进行向心/离心工作形式下的疲劳干预(连续踝关节背屈及跖屈运动),并于干预前后分别进行本体感觉测试及站立平衡测试,对目标角度(背屈10°、跖屈25°位)的绝对差值和身体摆动指数进行统计分析。结果:与干预前相比,疲劳干预后两组受试者目标角度的绝对差值增加(P<0.05),身体摆动指数增加(P<0.05);同时,离心疲劳干预组变化更为显著(P<0.05)。结论:踝关节周围肌肉疲劳引发其关节本体感觉及人体平衡控制能力下降,且在离心收缩引发的肌肉疲劳中更为明显。
Objective To explore the effect of concentric versus eccentric muscle fatigue on the ankle proprioception and balance ability. Methods Forty healthy male college students were randomly divided into a concentric and an eccentric exercise fatigue group(CEF and EEF group),each of 20.The CEF and EEF groups were asked to perform the ankle dorsiflexors and plantar flexorsto exhaustion respectively. The proprioception and single leg standing balance ability were assessed before and after the intervention,and the absolute difference of the target angle(10° dorsiflexion and 25° toe flexion) and the body swing index were measured. Results A significant increase was observed in the absolute difference of the target angle and the body swing index,with that of the EEF group significantly greater than the CEF group(P<0.05). Conclusion Ankle muscle fatigue can lead to the decrease of proprioception and balance ability,especially in the eccentric muscle contraction.
