| Outline of Final Research Achievements |
The purpose of the present study was to examine that effects of an enrich environment (EE) on spontaneous locomotor activity, skeletal muscle and anxiety-like behavior compared with a standard environment (SE). We observed that increased exercise activity in the enriched environment improved anxiety-like behavior and spatial learning and memory. Moreover, all hindlimb muscle wet weights per BW were greater in the EE group compared with the SE group. The EE substantially increased locomotor activity and induced muscle hypertrophy in rats. An enriched environment used in the present study appeared to increase rat skeletal muscle volumes without increasing physiological and/or psychological stress.
