A reduction in gluteus maximus (GM) strength may contribute to the etiology of musculoskeletal impairments and lower-extremity injuries. Currently, there is a paucity of evidence regarding the efficacy of implementing a short-term gluteal activation programme to improving muscle performance. Twenty four semi-professional rugby males were assigned randomly to a gluteal activation group (GLUTE) or a control group (CON). During the 6-week training intervention, the GLUTE and CON groups performed the same training, however that GLUTE group performed seven gluteal activation exercises three times weekly prior to their normal training sessions. Whilst the CON group performed the conventional training with no gluteal activation exercises. Electromyography (EMG) was measured during a maximal isometric unilateral squat (MVIC) and unilateral hip extension force from the left and right vastus lateralis, gluteus maximus, and biceps femoris. After 6 weeks of training there was no significant main or interaction effect (p > 0.05) of EMG and peak force for MVIC and hip extension between GLUTE and CON. The current gluteal activation programme did not enhance EMG activity and hip extension force therefore, the body-weight exercises may not have been sufficient to elicit the appropriate changes.
臀大肌(GM)力量下降可能导致肌肉骨骼损伤和下肢损伤的病因。目前,关于实施短期臀肌激活计划以改善肌肉性能的疗效,证据不足。24名半职业男性橄榄球运动员被随机分配到臀肌激活组(GLUTE)或对照组(CON)。在为期6周的训练干预期间,GLUTE组和CON组进行相同的训练,但GLUTE组在正常训练前每周进行三次七项臀肌激活练习。而CON组进行常规训练,不进行臀肌激活练习。在最大等长单侧深蹲(MVIC)期间测量肌电图(EMG),并测量左右股外侧肌、臀大肌和股二头肌的单侧髋关节伸展力。经过6周的训练,GLUTE组和CON组之间,MVIC和髋关节伸展的EMG和峰值力没有显著的主效应或交互效应(p>0.05)。因此,目前的臀肌激活计划并未增强EMG活动和髋关节伸展力,体重训练可能不足以引发适当的变化。
