The purpose of study was to investigate the changes in an index of appetite before and after the browsing food pictures or the performing of radio gymnastics after the awakening. Seventeen healthy students (age: 20±1) were volunteered to this study. The investigation was conducted every other week for three days. There were three different groups (pictures browsing group, gymnastics group, control group) each day. All groups were the same subject. The appetite index and the hunger index were estimated at wake-up, immediately after the intervention, and 10 minutes after the intervention. In the gymnastics group and the pictures browsing group, both indices increased significantly compared to the control group. We suggested that that result contributed to the promotion of appetite for breakfast.
