“运动教育模式”对学生运动强度的影响

Effects of “sport education mode” on student exercise intensity

通过监测普通高校学生在两种教学模式下的心率变化,调查学生不同强度运动时间比例的差异。采用随机抽样,遥测68名在校大学生在13节健美操课上的心率变化,以RS 800CX多项运动心率表为测量工具,设定两个靶心率,确定中等强度心率(>HRmax×64%)、较大强度心率(>HRmax×77%)、介于两者强度之间心率为3个观测区域。结果发现,在大多数课次上,学生在"运动教育模式"下的中等强度心率运动时间比例、较大强度心率运动时间比例、介于两者强度之间心率运动时间比例均显著高于"我国传统体育教学模式";在大多数课次上,学生在"运动教育模式"下的中等强度心率运动时间比例达到并超过了50%;前3次课是"运动教育模式"的泛化期,两种教学模式下,学生不同运动强度运动时间比例相似或相近。结果说明,采用"运动教育模式"作为普通高校健美操课的教学模式可以有效提高学生中等强度、较大强度的运动时效,从而提高教学效果。

In order to investigate the difference of students’ percentages of exercise time at different intensities by moni-toring 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 800CX 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 （＆gt;HRmax＆#215;64%）, higher intensity heart rate （＆gt;HRmax＆#215;77%）, and in-between intensity heart rate （HRmax＆#215;64%＆lt;x＆lt;HRmax＆#215;77%）, and revealed the following find-ings： in most classes, under “sport 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 “sport 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 “sport education mode”, in such a period, the students’ percent-ages of exercise time at different exercise intensities were similar or close under the two education modes. The said find-ings indicate that adopting “sport education mode” as a regular university aerobic dance class teaching mode can effec-tively enhance students’ time efficiency of exercise at a medium or higher intensity, thus enhance teaching effect.
