Abstract

The purpose of this study was to determine what effect rapid weight loss and subsequent weight gain had on muscular power of intercollegiate wrestlers. Body weight, total body water, muscular power of arm flexion and extension, and muscular power of leg flexion and extension were studied at three conditions: normal weight, dehydrated wrestling weight and in 6-hour rehydrated weight. Results showed that the subjects (n=10) lost 4.7% (3.3 kg) body weight and 6% body water (2.8 L) prior to the dehydrated test condition. The subjects employed food and fluid deprivation coupled with exercise in a heated wrestling room to lose this weight. Analysis by one-way repeated measures ANOVA revealed that there was a significant difference found for both the body weight and total body water measures {(F(2,18)=26.12, pc.OOl and F(2,18)=3.80, p<.042)}. Using a 3x3 repeated measures ANOVA, power during arm flexion and arm extension was significantly greater at a slow speed compared to intermittent and fast speeds {AF (F(2,17)=6.44, px.01) and AE (F(2,18) =19.91, p<.01)}. Subjects were able to regain losses of body weight and body water prior to the 6-hour rehydration testing condition by employing individual nutrition patterns which the • subjects normally use during the wrestling season. In conclusion, rapid reduction in the body weight of intercollegiate wrestlers through food and fluid restriction in association with exercise in a heated wrestling room can lead to significant reductions in weight and body water. In addition, upper body power measures at a slow speed are significantly different from power measures for a fast or medium speed.
