The Changes of Body Composition and Blood Elements by Weight Cycling in Wrestlers |
|
Abstract |
Ten wrestlers were used as human subjects and divided into two groups(weight cycle and non-weight cycle) in order to study the effects of 3 times weight cycling on body composition, waist to hip ratio and blood composition. The body composition including body fat, fat free mass were significantly increased in the weight cycling group by repeated weight cycling. The waist to hip ratio was considerably increased in the cycle group . The level of glucose and insulin in blood was not highly changed by repeated weight cycling, whereas the triglyceride was remarkably increased and decreased dependent on body weight during weight cycling. Free fatty acid concentrations in blood were in inverse proportion to body weight during weight cycling. These results suggest that body weight could not be efficiently reduced by the repeated weight cycling in certain period time, and physical ability for game might be decreased by increasing rate of body fat and decreasing rate of fat free mass according to the weight. |
