title: Effects of resistance training on sarcopenic obesity index in older women: A randomized controlled trial.
abstract: 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.
