Abstract
This study aimed to determine the effects of a 3-week self-managed weight loss on body mass and body composition in collegiate male judo athletes. Twenty male judo athletes were divided into two groups; weight loss group involving in a 3-week self-managed weight loss as well as judo’s specific training（N=10, WL）vs. control group involving in judo’s specific training alone. Whole body and regional fat（FM）and fat-free soft tissue masses（FFSTM）were determined by a duel X-ray absorptiometry. For control group, there were no significant changes in any variables. In the WL group, the self-managed weight loss decreased body mass and whole body FFSTM by 4% and 3.5%, respectively. Whole body FM tended to be decreased by the self-managed weight loss. Trunk FM and FFSTM were decreased, and legs FFSTM tended to be decreased by the self-managed weight loss. There were no significant changes in arms FM and FFSTM. These current findings indicate that a 3-week selfmanaged weight loss decreases whole body FFSTM, resulting from decreasing of trunk FFSTM in collegiate male judo athletes.
