男大学生跑台递增运动中最大摄氧量、无氧阈的测定与分析

Measurement and Analysis of Maximal Oxygen Uptake and Anaerobic Threshold in Male Students during Treadmill Incremental Exercise

本研究采用跑台递增运动方式测定10名男大学生的最大摄氧量、无氧阈,分析两者的关系.测得最大摄氧量平均值为4.62±0.96升/分,无氧阈时的摄氧量、最大摄氧量百分数、心率分别为3.05±0.74升/分、65.89%±6.99%、166.5±7.6次/分;最大摄氧量与无氧阈时的摄氧量呈显著性正相关,与无氧阈时的最大摄氧量百分数无显著性相关.研究结果表明;(1)受试者采用跑台负荷方式测得的最大摄氧量水平较高;(2)最大摄氧量和无氧阈时的最大摄氧量百分数在评定身体机能和身体素质、安排运动训练及选拔运动员中所起的作用不同.

The purpose of the study is to measure maximal oxygen uptake (Vo_2max) and anaerobic threshold (AT) of 10 male students (20-22yrs) in treadmill exercise and to analyse the relationship between the above indexes. The mean value of Vo_2max is 4.62±0.96 L/min (68.85±13 86 ml/kg/min) and the mean values of Vo_2 (Vo_2-AT), %Vo_2max and HR (AT-HR) at AT are 3.05±0.74 L/min, 65.9±7.0 %Vo_2max, 166.5±7.6 beats/min respectively. Vo_2max is significantly correlated with AT (%Vo_2max) (r=0.159, p>0.05). The results Show: (1) The value of Vo_2max of the students is greater; (2) Vo_2max and AT paly different roles in evaluating the physical fitness and condition and in selecting athletes with potential.
