説明
The present study was designed to investigate changes in sodium (Na), potassium (K), calcium (Ca), magnesium (Mg) and phosphorus (P) balances during a daily exercise regime of 3h/day under dietary conditions that maintained an nutrient intake with an energy intake of 1, 000 kcal/day. The subjects were five healthy men, and the experiment consisted of 5 days of exercise preceded by 6 days of rest. During the exercise period, exercise was performed for 90 min with a bicycle ergometer at a target intensity of 60% VO2 max every morning and afternoon. Extra energy was added by increasing the experimental food intake in proportion to energy intake. The increases in sweat Na, K, Ca and Mg excretion over the levels during the rest period were lower than the increases in their intake. Na and P retention due to a decrease in urinary excretion was observed, but K, Ca and Mg balances were unchanged. The level of serum parathyroid hormone (PTH44-68) was increased early in the exercise period, but decreased later. These results suggest that a dietary regime that maintains nutrient intake per 1, 000 kcal of energy intake during exercise is reasonable for these minerals.
