The purpose of this study was to examine the effects of resistance training (RT) on sarcopenic obesity (SO) in older women. 243 older women underwent body composition measurement using dual-energy X-ray absorptiometry, and the SO index was calculated. This randomized controlled trial adopted from the baseline sample, 113 volunteers (67.0±5.2years) were randomly assigned to a control group (CG, n=64) or an experimental group (EG, n=69). The EG took part in a 24-week RT program, conducted three times per week. Body composition measurements were repeated at the end of the training program. RT induced a significant increase in fat-free mass (P<0.01), but not decrease in fat mass in the EG. Moreover, the SO index was also significantly improved in the EG (P<0.01), while it decreased significantly in the CG (P<0.01). It is concluded that RT is an effective approach to promote body composition alterations in older women, and it might improve SO-related phenotypes.
本研究旨在探讨抗阻训练（RT）对老年女性肌少性肥胖（SO）的影响。243名老年女性采用双能X线吸收法进行身体成分测量，并计算SO指数。本随机对照试验从基线样本中选取，113名志愿者（67.0±5.2岁）被随机分为对照组（CG，n=64）或实验组（EG，n=69）。实验组参加了为期24周的抗阻训练计划，每周进行三次。在训练计划结束时重复进行身体成分测量。抗阻训练使实验组的去脂体重显著增加（P<0.01），但脂肪量没有减少。此外，实验组的SO指数也显著改善（P<0.01），而对照组则显著下降（P<0.01）。得出结论，抗阻训练是促进老年女性身体成分改变的有效方法，并且可能改善与肌少性肥胖相关的表型。
