摘要

这项交叉试验旨在调查在倾斜平台上进行单侧北欧腘绳肌运动的额外负荷是否会增加股二头肌长头肌电图活动。参与者被随机分配在三种条件下进行单边北欧腿筋运动:分别是体重(BW)或BW加上3公斤(BW + 3公斤)或6公斤(BW + 6公斤)的加重球。体重+ 6 kg组股骨二头肌长头肌电活动显著高于体重和体重+ 3 kg组(p < 0.01)。因此，在倾斜平台上增加单侧北欧腘绳肌运动负荷，可能对腘绳肌劳损的康复和预防复发有效。

Changes in Amplitude of Hamstring Electromyographic Activity and Its Peak Location During Nordic Hamstring Exercise by Adding External Load

This crossover trial aimed to investigate whether additional loading of unilateral Nordic hamstring exercise on a sloped platform would increase the biceps femoris long head electromyographic activity. Participants were randomly allocated to unilateral Nordic hamstring exercise under three conditions: bodyweight only (BW) or BW with an added weighted ball of 3 kg (BW + 3 kg) or 6 kg (BW + 6 kg), respectively. The biceps femoris long head electromyographic activity was significantly higher for BW + 6 kg (p < .001) than for BW and BW + 3 kg (p < .01). Therefore, adding a load to unilateral Nordic hamstring exercise on a sloped platform might be effective for rehabilitation and prevention of hamstring strain injury recurrence.
