The purpose of this study was to investigate the effects of two states of hydration has an effect on muscular endurance in men. Two groups of four men randomly assigned to each group participated in both states of hydration. Both groups were tested at baseline for height, weight, intra- and extra-cellular water, total body water, and a one-repetition maximum strength test. Subjects were then tested after a 24 hour period of water deprivation, and after a 24 hour period of normal water intake (8 ten oz glasses of water). A urine specific gravity test, intra- and extra-cellular water, total body water, and weight were used to determine hydration. A maximum repetition test at 50 percent of the subjects 1RM was used to determine muscle endurance. Results showed that there was no statistical significance (p<.05) between hydration and muscular endurance at a decrease of one percent total body weight. It was concluded that while in the literature it may appear that there may be a relationship between hydration and performance, there was no statistical difference between the two states of hydration in this experiment.
