背景资料：加强和激活臀大肌和臀中肌，同时尽量减少阔筋膜张肌的作用，是治疗许多下肢损伤的重要组成部分。以前的研究人员已经评估了无数的运动，激活臀大肌（GMax）和臀中肌（GMed），然而，有限的研究已经进行了描述的作用，增加弹性阻力常用的演习。目的：本研究的主要目的是确定臀阔筋膜张肌的激活（GTA指数），并比较肌电图肌肉激活的GMax，GMed和TFL，同时执行13个常见的处方演习，旨在目标GMax和GMed。本研究的第二个目的是比较肌肉激活的GMax，GMed，TFL，同时执行一个亚组的三个匹配的练习，并没有弹性resistance.Study设计：重复测量队列studyMethods：一个样本的11个健康，身体活跃的男性和女性，腰痛和下肢损伤，被招募的研究。在进行13次运动时，使用表面肌电图来量化臀大肌、臀中肌和阔筋膜张肌的标准化EMG激活。其中三个练习是在有和没有弹性阻力的情况下进行的。建立了最大的自愿等长收缩，为每块肌肉和顺序进行的演习是随机的，以尽量减少疲劳的影响。结果：臀肌的相对激活进行了比较阔筋膜张肌，并表示为GTA指数。有阻力和无阻力的蛤蜊、在稳定性训练器上进行的跑步者臀大肌训练和有阻力的桥牌运动分别产生了最高的GTA指数。有阻力和无阻力的蛤蜊之间TFL的激活存在显着差异。结论：研究结果与之前研究人员的报告一致，他们报告称蛤蜊运动可以最佳地激活臀肌，同时最大限度地减少阔筋膜张肌的激活。
Background: Strengthening and activation of the gluteus maximus and gluteus medius while minimizing the contribution of the tensor fascia latae are important components in the treatment of many lower limb injuries. Previous researchers have evaluated a myriad of exercises that activate the gluteus maximus (GMax) and gluteus medius (GMed), however, limited research has been performed describing the role of the addition of elastic resistance to commonly used exercises.Purpose: The primary purpose of this study was to determine the gluteal-to-tensor fascia latae muscle activation (GTA index) and compare electromyographic muscle activation of the GMax, GMed, and TFL while performing 13 commonly prescribed exercises designed to target the GMax and GMed. The secondary purpose of this study was to compare muscle activation of the GMax, GMed, and TFL while performing a subgroup of three matched exercises with and without elastic resistance.Study Design: Repeated measures cohort studyMethods: A sample of 11 healthy, physically active male and females, free of low back pain and lower extremity injuries, were recruited for the study. Surface electromyography was used to quantify the normalized EMG activation of the gluteus maximus, gluteus medius, and tensor fascia latae while performing 13 exercises. Three of these exercises were performed with and without elastic resistance. The maximal voluntary isometric contraction was established for each muscle and order in which the exercises were performed was randomized to minimize the effect of fatigue.Results: The relative activation of the gluteal muscles were compared to the tensor fascia latae and expressed as the GTA index. Clams with and without resistance, running man gluteus maximus exercise on the stability trainer, and bridge with resistance, generated the highest GTA index respectively. Significant differences in activation of the TFL occurred between clams with and without resistance.Conclusions: The findings are consistent with those of previous investigators who reported that the clam exercise optimally activated the gluteal muscles while minimizing tensor fascia latae activation.
