| Outline of Final Research Achievements |
The purpose of this study was to clarify the effects of exercise on skeletal muscle, neurotransmitters, and mental health using an animal model. The present results indicated that enriched environments, which increase voluntary exercise, increased muscle mass of tibialis anterior and circulating noradrenaline. In contrast, enriched environments reduced anxiety-like behavior. At the current stage, there are no clear relationships between skeletal muscle activation and improvements in mental health. However, the present results suggest that skeletal muscle activation may potentially contribute to improvements in mental health. Further studies are required to elucidate mechanisms underlying improvements in mental health induced by exercise.
