ABSTRACT

The aim of this study was to examine the effects of 8 weeks beta-hydroxy-beta-methylbutyrate
(HMB) supplementation with resistance training on some components of physical
fitness and body composition in young males. Twenty healthy young men
volunteered to participate for the study and divided into two groups and
performed 8-week resistance training while supplementing with either HMB or
placebo (3 g per day). The subjects were evaluated for 1 repetition maximum
(1RM) bench press and leg press, vertical jump (VJ), anaerobic power (RAST)
prior to and after training intervention. In addition, body composition
variables such as percent body fat, and BMI were assessed per and post training
period. Both the groups showed significant increases in 1RM bench press and leg
press, VJ, and anaerobic power (RAST), and also the HMB supplementation group
showed greater gains compared with the placebo. In addition, percent body fat
decreased significantly in HMB and placebo groups. BMI enhancements were
greater for the HMB supplementation group indicated gains in body weight.The results indicated that resistance training improved physical
performance and HMB supplementation induced greater gains and therefore it
could be recommend to coaches and athletes who use this supplementation to
greater gains in physical fitness variables.
