Effects of “sport education mode” on student exercise intensity

In order to investigate the difference of students' percentages of exercise time at different intensities by monitoring the changing of heart rate of regular university students under two teaching modes, the authors, by following the principle of random sampling and by using RS 800 CX multi-exercise heart rate meter as a measurement tool, remotely measured the changing of heart rate of 68 current university students during 13 aerobic dance classes, set two target heart rates, determined 3 observation areas, namely, medium intensity heart rate(HRmax×64%), higher intensity heart rate(HRmax×77%), and in-between intensity heart rate(HRmax×64%xHRmax×77%), and revealed the following findings: in most classes, under education mode, the students' percentage of exercise time at a medium intensity heart rate, percentage of exercise time at a higher intensity heart rate and percentage of exercise time at an in-between intensity heart rate were all significantly higher than those under traditional Chinese sport teaching mode; in most classes, under education mode, the students' percentage of exercise time at a medium intensity heart rate reached and exceeded 50%; the first 3 classes were the generalization period of education mode, in such a period, the students' percentages of exercise time at different exercise intensities were similar or close under the two education modes. The said findings indicate that adopting education as a regular university aerobic dance class teaching mode can effectively enhance students' time efficiency of exercise at a medium or higher intensity, thus enhance teaching effect.
