Abstract:
This investigation was directed to the physiological load intensity in the curricula of track and field studies offered in 8 general colleges. We adopted the sampling survey method and monitored the heart rate of 80 first-year students who were from different grades in 8 colleges and were attending the track and field class. The data collected from these male student show: (1) The pre-exercise heart rate is 80 per minute; the first inflection point appears at 28 minutes after exercise; the heart rate is 132 per minute and the slope is -0.031. (2) The data of exercise load at mobilization stage and at fatigue stage are 90.09 and 104.126 kUw respectively; the data of lasting time are both 28 minutes, and the average heart rates are 133 per minute and 140 per minute respectively. The exercise load is 84.231 kUw at stable stage. (3) When the heart rates are 120-140 per minute and 140-150 per minute respectively, the ratios of load are 32.786% and 31.316% respectively. When the heart rate is 120-150 per minute, the ratio of load is 64.102%. But we are surprised to find that when the heart rate is 150-160 per minute, the ratio of load is only 17.639%. In the analysis of data from this investigation we have noticed that the physiological load intensity is in accord with the changing rule of body function. In order to further adjust the training plan and arrange the load of exercise rationally and promptly, we, the teachers, should pay adequate attention to the heart rate monitoring data on students.
