Abstract

The purpose of this study was to examine the effects of a combination of effervescent creatine, ribose, and glutamine on muscular strength (MS), muscular endurance (ME) and body composition (BC) in resistance-trained men. Subjects were 28 men (age: 22.3 ± 1.7 years; weight: 85.8 ± 12.1 kg; height: 1.8 ± 0.1 m) who had 2 or more years of resistance-training experience. A double blind, randomized trial was completed involving supplementation or placebo control and a progressive resistance-training program for 8 weeks. Dependent measures were assessed at baseline and after 8 weeks of resistance training. Both groups significantly improved MS and ME while the supplement group significantly increased body weight and fat-free mass. Control decreased body fat and increased fat-free mass. This study demonstrated that the supplement group did not enhance MS, ME, or BC significantly more than control after an 8-week resistance-training program.
