| Outline of Final Research Achievements |
The purpose of this study was investigated the correlation between increase and inhibition of autonomic nervous system and body temperature accompanied by diurnal variation and motor unit of recruitment threshold were compared in the morning (AM:9-10) and afternoon (PM:5-6). The test responses of autonomic nervous system activation accompanying rest were not observed effects in the AM and PM. In the response by exercise intensity, the loop time did not change in both AM and PM under no-exercise and low intensity exercise condition. The loop time of immediately after exercise was shortened as compared to the pre-exercise level only the medium intensity exercise condition at AM. In the high intensity exercise conditions, both in the AM and PM, the loop time were shorted immediately after exercise. It was suggested that the difference in the response of the loop time after medium intensity exercise at AM and PM influenced by the diurnal rhythm of body temperature.
