Abstract

Aim: Today, the role of some nutritional supplements maintaining soft lean mass and obesity treatment has been proven. Among these supplements, beta-hydroxy-beta-methyl butyrate (HMB), has become popular recently. The aim of the present study was to investigate the effect of 6-week HMB supplementation on muscle strength and body composition of overweight sedentary women. Methods: Forty 20-45-year-old female were recruited to the study. The subjects were randomized to an HMB supplement (n = 20) or placebo (n = 20) group. Body composition was measured by body impedance analyzer. Strength was evaluated by one repetition maximum (1RM) measurements for upper and lower body using body solid leg press and chest press machines. Results: Thirty-five participants were analyzed at the end of the study. Changes in the 1RM strength tests in the upper and lower body were significant between the two groups after 6 weeks (p = 0.01 and p = 0.04 respectively). The changes in body composition indices were not significant between the two groups (p > 0.05). Conclusions: Based on the results of the present study, six weeks of HMB supplementation in overweight women increased the muscle strength compared to the control group. © 2019 Elsevier Ltd
