| Outline of Final Research Achievements |
A summary of the research findings
In 1,500-meter trials, the time was 5.9 seconds faster (2.1%) when the runner had been accompanied by another student (p<0.05) because he had been more motivated. However, when the runner had run side by side with another student on a treadmill in a room, there were no significant differences in the physiological and psychological factors, although the subjects were able to run 12 seconds (3.9%) longer than when they ran alone. In 1,500-meter trials, the performance of students was more favorable when they had been accompanied by another runner due to an increase in the level of psychological activity prior to the trials. As a result of the increase, the output of aerobic energy increased immediately after the runners had started to run and that of anaerobic energy was reduced. The runners were presumably able to utilize the amount of energy saved in the process during the trials including their final phases.
