It is widely recognized that fluid intake during exercise is effective in preventing heat stroke and maintaining exercise performance in a hot environment. However, kendo players have traditionally restricted fluid intake during training, even in a hot environment, in order to cultivate their spirit.Research involved a study of the fluid intake of kendo players of a college team participating in a summer training camp. Twenty-two kendo players (15 male, 7 female) participated in the summer camp of August in 1997. Trainings in the camp were held twice a day (once in the morning and in the afternoon, respectively). Fluid volume intake of each player in training was measured, as was body weight before and after training, and environmental conditions (i. e. dry-bulb temperature and relative humidity) during training session in the camp.The players took in fluids in a total of 1477. 1 ± 685. 7ml in each training (201. 7 士 256. 1ml, 320. 3 ± 178. 9ml / hr, and 537. 0 土 347. 5ml before, during and after training, respectively). The real body weight loss (i. e. body weight loss corrected by fluid volume intake) was 2. 4 土 1. 1kg, although body weight loss after training was 0. 9 ± 0. 8kg. There was a significant regression between fluid volume intake and the real body weight loss (r = 0. 614, p く 0. 05). The regression analysis showed a regression coefficient of 0. 401, indicating that the rate of fluid volume intake to fluids volume secretion from the body was 40. 1%. It is vital for kendo players to intake fluids much more frequently during training in a hot environment, and their coaches must design training programs in which the players are able to do so.
