摘　　要：该文以体育学院大学生为研究对象,利用跑步机通过递增负荷运动进行乳酸阈的实验测试,观察血乳酸阈与乳酸阈心率的特点。实验结果显示,体育学院大学生乳酸阈平均值为4.39±0.81mmol/L,递增负荷运动中血乳酸峰值为16.38±0.97mmol/L,运动中心率与血乳酸呈正相关,乳酸阈心率平均为131±18.5次/min。因此,在运动中可充分利用乳酸阈心率合理安排训练强度,以期为大学生有氧运动负荷提供实验数据支撑。In this experiment,the students of Institute of Physical Education were taken as the research object,and the lactic acid threshold was tested by increasing load exercise with treadmill,and the changes of blood lactic acid and heart rate were observed.The experimental results show that the lactic acid threshold of college students in Physical Education Institute is 4.39±0.81 mmol/L,and the peak value of blood lactic acid in incremental exercise is 16.38±0.97 mmol/L.At the same time,the exercise center rate is positively correlated with blood lactic acid,and the threshold heart rate of lactic acid is 131±18.5 beats/min.Therefore,we should make full use of lactic acid threshold heart rate to arrange training intensity reasonably in scientific sports,in order to provide experimental data support for college students'aerobic exercise load.
