The side-lying hip abduction exercise is one of the most commonly used exercises in rehabilitation to increase hip abduction strength, and is often performed without external loading. The aim of this study was to compare the effect of 6 weeks of side-lying hip abduction training, with and without external loading, on hip abduction strength in healthy subjects. Thirty-one healthy, physically active men and women were included in a randomised controlled trial and allocated to side-lying hip abduction training, with or without external loading. Training without external loading was performed using only the weight of the leg as resistance, whereas training with external loading was performed with a relative load corresponding to 10 repetition maximum. Hip abduction strength was measured pre- and post-intervention. Isometric and eccentric hip abduction strength of the trained leg increased after hip abduction training with external loading by 12% and 17%, respectively, (P<0.05). Likewise, isometric and eccentric hip abduction strength of the trained leg increased after hip abduction training without external loading by 11% and 23%, respectively, (P<0.001). The strength increases were not different between groups (P>0.05). Six weeks of side-lying hip abduction training, with or without external loading, increases isometric and eccentric hip abduction strength to the same extent.
侧卧位髋关节外展练习是康复中最常用的练习之一，用于增加髋关节外展力量，通常在没有外部负荷的情况下进行。本研究旨在比较 6 周的侧卧位髋关节外展训练，有无外部负荷，对健康受试者髋关节外展力量的影响。31 名健康、活跃的男性和女性被纳入一项随机对照试验，并被分配到侧卧位髋关节外展训练，有无外部负荷。无外部负荷的训练仅使用腿部重量作为阻力，而有外部负荷的训练则使用相当于 10 次最大重复次数的相对负荷。在干预前后测量髋关节外展力量。经过有外部负荷的髋关节外展训练后，训练侧的等长和离心髋关节外展力量分别增加了 12%和 17%（P<0.05）。同样，经过无外部负荷的髋关节外展训练后，训练侧的等长和离心髋关节外展力量分别增加了 11%和 23%（P<0.001）。两组之间的力量增加没有差异（P>0.05）。6 周的侧卧位髋关节外展训练，有或没有外部负荷，都能同等程度地增加等长和离心髋关节外展力量。
