| Research Abstract |
Investigations by questionnaires and experiments revealed the following findings. 1. Contrastive audio-visual stimuli edited by us, which were consisted of video-taped laughing or shocking scenes, caused contrastive chages in mental and immunological states. Laughing scenes produced increase of activity and decreases of negative mood such as tension, anxiety, confusion and depression. Schoking scenes caused the opposite changes of mood state and decrease of NK activity. Jogging did not cause much change in either state. 2. Long-term mental and physical effects of aerobic exercise approximately twice a week for two months were significantly observed: decreases in anxiety, depression, body weight and body-fat percentage, and increase in vigor and anaerobic power. No significant long-term immunological change were observed. 3. Long-term mental effects were not observed in the young female athletes control group. 4. Long-term mental effects were not in a parallel relationship with physical effects. 5. Mental effects were more remarkable among those with higher trait anxiety or in a higher age group.
