Abstract
Our aims are clarifying the facts on fluid replacement and studying the awareness of fluid replacement for people who exercise at the indoor pool. The investigation was conducted in the form of a questionnaire. The number of subjects was 1005 (56.0±15.3yr). While exercising, the subjects who thought that they had to replace fluid whether they felt thirsty or not in both men and women were most common among the subjects younger than the age of 44 but least common among the subjects older than 65. The subjects who replaced fluid before, after, and during exercise were most common among men younger than the age of 44 in all cases, but women did not differ significantly by age. The subjects who replaced fluid after exercise were 77 to 94% of the total, whereas the subjects during exercise were 15 to 34%. As many as 12.7% of subjects did not replace fluid before, after, and during exercise. The reason the subjects did not replace fluid was to have only a limited knowledge about fluid replacement. At aquatic exercise, the subjects who had experienced subjective symptoms which appeared to be dehydration was 57.1%. When taken together, our study demonstrated the need to educate people who performed aquatic exercise regarding fluid replacement.
