To examine the psychophysiological influences of physical exercise on the increase in positive affects, fifteen male students, aged 18 ± 0.6 years, participated in comforable selfpaced running. The subjects ran at their own pace for fifteen minutes on a flat treadmill. During the exercise, only the following three methods of evaluation were employed, so that the subjects remained disturbed as little as possible. Changes of heart rates were measured by using telemetery, and the evaluation of mood alteration and rating of perceived exertion (RPE) were asked orally. The mood states as a psychological variables were assessed by using mood check list (MCL) and MCL short form. Blood samples were collected before and after running exercise. The mean RPE and the mean heart rates were 11.7 ± 0.8, 141 ± 19.8 beats/min respectively. These values were equivalent to 55.8 ± 10.7% of their maximal aerobic power, and were maintained near their anaerobic threshold. Positive affects 'pleasantness' and 'satisfaction' were increased, but the negative affect 'anxiety' was not significantly changed. The plasma ACTH and serum cortisol, and the levels of plasma β endorphin were not significantly changed between before and after exercise. In additional experiments with lower intensity running, neither physiological nor psychological values were significantly changed. These results suggest that the mood alteration by exercise may be related to the exercise intensity, especially at the levels of anaerobic threshold. The increases in positive affects observed during exercise, support the continued practice and application of exercise prescription.
