| Research Abstract |
To determine whether factors such as age and physical activity level influence body water balance, body water turnover was investigated in a study population that included both young and elderly subjects. In conclusion, body water turnover decreases with age. In the case of individuals of the same age group, the percentage of body water turnover for the exercise group was significantly higher than that for the sedentary group. Body water turnover was found to be correlated with aerobic fitness and physical activity levels. Furthermore, body water turnover in the elderly was found to be related to the physical activity level, regardless of the level of kidney function.
