Effects of the exercise on physical and mental health were investigated for sound female college students, about 20 years old. Bicycle exercise setting exercise intensity within 40-70 % of maximum heart rate was carried out for 6 min, after free exercise with quickness for 3 min. These exercises were carried out at the rate of 1-3 times a week during 3 weeks. The exercise showed a tendency to increase the level of resting energy expenditure(REE), though it produced no significant change in such body composition as height, body weight and somatic fat rate. The arterial oxygen content was decreased by the first experiment of exercise training of total 3 times, but this did not appear in later experiments. Whereas, the venous oxygen content was not affected. It was indicated that the exercise significantly reduced the mental fatigue degree by some evaluations with a self-recording questionnaire. From the above result, the exercise accelerated REE, and was adapted to the exercise environment. These results suggested that the exercise may enhance the activity of oxygen transport and oxygen reception in organization, and lead to the appearance of an exercise adaptation.
