踏台昇降運動における心拍数におよぼす W-up の影響

抄録

This research aimed at the analysis of the changes in the heart rate caused by the training load given to young students. The experimental subjects in this research were 5 healthy male athletes in senior high school. All the subjects performed the stepping up-down exercise of 5 minutes duration with a frequency of 36 steps per minute using steps 35cm hight. The heart rate responses were recorded every 10 seconds by heart checker just before, during the stepping exercise and in the recovery period after the stepping exercise. The accumulated heart rate were calculated from the beginning of the stepping exercise, for 5 minutes during the stepping exercise and for 5 minutes after the stepping exercise. After the stepping exercise the subjects were required to sit on the bench for 5 minutes with out moving. And all the subjects participated in the measuring two times a week for three weeks. The results obtained were as follows : There were considarable differences in the accumulated heart rate obtained in case of after the training loaded and without training load in the 1st round measuring. But in the pair of 2nd, 3rd round measuring were not significant. In this case, the accumulated heart rate when after the training loaded showed no difference compared to that of the other rounds, while the results obtained when without the training load were clearly lower than the others. In case of after the training loaded, there were no direct linear relation between the stepping rounds and the accumulated heart rate during, after and the total of exercise.
