摘要
目的:利用跑步机进行最大耗氧量(VO2max)的间接测量方法研究,探索一种简便有效、适用于普通大众的心、肺耐力检测与评估方法。方法:以某大学48名男性大学生为研究对象,分别用直接测试法、二次跑台推测法、改进的PCIO推测法计算VO2max,分析三者相关性。结果:1)针对青少年男性人群,选用10.2 METs与12.1 METs运动强度阶段的二次跑台推测法的预测结果与直接测试法得到的VO2max之间具有显著相关性(r=0.569,P<0.001)。2)改进PCI推测法,制定新的参数PCIO=3.5×(运动强度-1)/(运动HR-静息HR)。10.2 METs与12.1 METs运动强度下的PCIO值之间具有强相关性(r=0.774,P<0.01)。3)PCIO推测法得到的VO2max与直接测量法得到的VO2max具有强相关性(r=0.661,P<0.001)。结论:1)针对青少年男性人群,选择10.2 METs与12.1 METs 2个运动强度作为二次跑台推测法的2个运动强度阶段,推测得到的VO2max可以有效评估测试者的心、肺耐力,但最大心率的估计、运动强度的选择影响评估的有效性。2)改进的PCIO推测法只需要测量1个运动强度阶段,测试方便快捷、易于实施与控制,相对二次跑台而言评估效果更好,可以成为新的简便有效的大众心、肺功能间接测量方法。
Objective:Using treadmill to find indirect measurement methods of VO2max,explore a simple and effective cardiorespiratory endurance testing and evaluation methods,which is applicable to the general public.Methods:Taking 48 male college students as the research object,using the direct test method,secondary treadmill prediction method,improved PCIOprediction method to calculate VO2max and analyze the correlation of the three methods.Results:1) for young male population,there is a significant correlation(r=0.569,P&lt;0.001) between the secondary treadmill prediction method(use 10.2 METs and 12.1 METs) and the direct test method.2) improve the PCI(Physiological Cost Index) prediction method,define a new parameter PCIO=3.5×(exercise intensity-1) /(exercise heart rate-resting heart rate).There is a significant correlation(r=0.774,P&lt;0.01) between the PCIO value under 10.2 METs and the PCIO value under 12.1 METs.There is a significant correlation(r=0.661,P&lt;0.001) between the PCIO prediction method and the direct test method.Conclusion:1)For young male population,select 10.2 METs and 12.1 METs to predict VO2max with the secondary treadmill prediction method,could effectively assess cardiorespiratory endurance,but estimate of the maximum heart rate and the the choice of exercise intensity affect the validity of the assessment.2)The PCIO prediction method only need to measure in one phase,compared to the secondary treadmill prediction method,it is convenient and fast,easy to implement and control,and can be a new indirect measurement method of cardiorespiratory endurance for the general public.
