Creatine May Enhance Body Weight, Strength
GLASGOW, United Kingdom--Five days of creatine supplementation was shown to increase body weight and fat-free body mass in resistance-trained men, according to research published in the July issue of Medicine & Science in Sports & Exercise (34, 7: 1176, 83, 2002) (www.ms-se.com). Researcher, from the University of Glasgow also noted creatine supplementation improved peak force and total force during repeated bench-press exercises compared to the placebo group.
Thirty-two men accustomed to weight training were randomly assigned to receive either creatine (20 g/d plus 180 g/d of dextrose) or placebo (200 g/d of dextrose) for five days. Subjects in the creatine group were categorized into "responders" (n=17) and "nonresponders" (n=4). In analyzing data from the responders group, researchers noted that the change in peak force and total force were significantly greater compared to the placebo group, with estimated creatine uptake being inversely correlated with training status. Researchers also noted a significant increase in body weight and fat-free mass, with the magnitude of increase being significantly greater in the responder group than the placebo group.
