Effects of drinking on body temperature during exercise and recovery in heat were studied in the field. Five healthy baseball players participated in baseball training with and without fluid re-placement on summer days, and rectal temperature, body weight loss, rating of thirst and the amount of water consumption were measured.<BR>The rectal temperature was significantly lower throughout exercise when fluid replacements were allowed. The normalization of rectal temperature during rest periods was also significantly accelerated by fluid replacement. The rating of thirst was significantly correlated with the increase in rectal temperature and sweat loss, and also with the volume of fluid intake. Although full rehydration was not observed, body fluid replacement by drinking is suggested to be advantageous for body temperature regulation during exercise in heat.
