      摘要:目的:通过进行1 km步行试验得到步行结束时的心率和行走所用的时间,再结合受试者的性别、年龄、身高、体重等指标来推测最大摄氧量,建立回归方程。方法:受试者为年龄在40~49岁之间的健康成年人,其中男性30人、女性34人,首先进行身高、体重等静态指标的测量,然后在功率车上进行递增负荷试验并结合气体分析直接测出最大摄氧量,对完成最大摄氧量测试的受试者择日再进行1 km步行试验,此试验进行两次,记录相应的心率值和行走时间取平均值用于计算。结果:将各指标进行回归分析得到回归方程,交叉验证回归方程显示最大摄氧量实测值和推测值的相关性统计量为RLOOCV= 0.826, SEELOOCV=0.378(L/min)。结论:采用1 km步行试验并使用此方程可以有效的推测40~49岁健康成年人的最大摄氧量。
英文摘要:
      Abstract:Objective: The purpose of this investigation was to explore a field test to predict maximal oxygen consumption of healthy adults using a 1-km walk test and the indicators of their sex,age,height and weight. Method:Maximal oxygen consumption was determined in healthy adult subjects(males=30,females=34)aged 40 to 49 years using a bicycle protocol.Before the exercises,their height,weight and other static indicators were measured.And then they took load incremental test on the ergometry cycle and their maximum oxygen consumption was test directly by gas analysis. And the subjects who completed this test performed the 1-km walking test the other day. The experiment was conducted twice.Result:Multiple regression analysis to predict maximal oxygen consumption yielded the following predictor variables: heart rates(HR)and walking time(WT)at the end of the walk;sex;age;height;weight.Result:The best equation was: Comparing observed and predicted maximal oxygen consumption values using a leave-one-out cross-validation resulted in RLOOCV=0.826,SEELOOCV=0.378(L/min). Conclusion: The results indicate that this 1-km walk test protocol provides a valid field test to predict maximal oxygen consumption of healthy adults aged 40 to 49 years.
