摘　　要：调查普通高校田径教学课中的生理负荷强度分布。采用抽样调查的方法,对80名普通高校一年级不同班级学生,在上田径课时的运动心率进行了监测调查。结果显示:(1)生理负荷变化的瞬时时间点,开始时刻心率为80次/min,第一拐点出现的时间是运动开始后的第28 min,此时的心率是132次/min,斜率是-0.031,表示心率变化的快慢和方向。(2)动员阶段和疲劳阶段都持续了28 min左右,负荷量分别是90.09 kUw和104.126 kUw(kUw,表示单位)。在动员阶段的平均反应强度是133次/分,而在疲劳阶段达140次/min。稳定阶段的负荷量是84.231 kUw。(3)各强度水平区间(PMI max)负荷量的分布情况。心率在区间120～140次/min和140～150次/min,负荷比值分别占总的32.786%和31.316%。心率在120～150次/min之间,负荷比值达到64.102%,而在150～160次/min之间,负荷比值仅占17.639%。普通高校田径课的生理负荷强度分布符合人体机能变化规律,但生理负荷强度处在较低的水平,不能充分起到增强和提高学生体能、体质的目的。教师应充分重视心率在训练过程中的实时监控作用,及时调整教学训练计划,科学合理地安排负荷强度和负荷量的大小。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 104.126kUw 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.
