YOSHIDA, T., TAKANISHI, T., NAKAI, S., YORIMOTO, A. and MORIMOTO, T., Relationship between Dehydration, Rehydration and Decreases in Esercise Performance During Various Sports in Hot Environments. Abv. Exerc. Sports Physiol., Vol.8, No.3 pp.71-76, 2002. The purpose of this study was to analyze the effects of dehydration and rehydration on exercise performance during sports activities in summer. We repeated measurements of the step test score (STS), vertical jump (VJ), side step (SS),back strength (BS), and whoke body reaction time (RT) before and after sports activities of Judo (n=9), Tennis (n=6), American footboll (n=8), and Baseball (n=7). the subjects were allowed free access to a sports beverage during each sport activity. Body mass loss(△mb, % of initial body mass), total sweat loss (msw,tot), and rehydration level (REH, % of fluid intake to msw,tot) were slso determined, and correlations between each parameter and changes of exercise performance were assessed. The STS significantly (p<0.05) decreased while VJ, BS, SS, and RT showed no significant decrease with sports activity. In all of the subjects (n=30), the change in STS(%STS) correlated significantly with △mb(r=-0.649, p<0.001) and the RED (r=0.589, p<0.001), but not with msw,tot. However, VJ, BS, SS, and RT were not correlated with △mb, REH or msw,tot. These results suggest that a decrease of aerobic performance is found during various sports activities in hot environments, and it is related to the degree of dehydration and rehydration during sports activity.
