最大摄氧量已被用作身体健康的衡量标准。当久坐不动的人变得更活跃时，这一指标增加了约25%。实验室中的摄氧量测量或现场工作中的估计是复杂且昂贵的，并且具有有限的风险。在本研究中，36名男性和32名女性完成了Paffenbarger体力活动指数问卷，包括出汗诱导的体力活动频率问题，并在踏板测力计期间测量了摄氧量。使用最大摄氧量作为健康的衡量标准，Paffenbarger体力活动指数虽然更详细，但可能不如简单的汗液诱导频率问题有效。出汗问题和摄氧量之间的相关性为0.54男性，0.26女性，0.46为总组。体力活动指数和摄氧量之间的相关性为0.26男性，0.08女性，和0.29的总组。回归关系（摄氧量= 1.92 × 1.95）为：（出汗天数）+23.76;估计的标准误差= 8.63 m/kg/min）对于出汗与氧摄取是显著的。虽然置信区间限制了预测个体值的实际能力，但低成本、无风险和群体有效性表明，对于流行病学研究，可以通过简单的汗液问题快速简单地评估健身情况。
Maximal oxygen uptake has been used as a measure of physical fitness. This measure increases by approximately 25% when sedentary individuals become more physically active. Oxygen uptake measurement in the laboratory or estimation in fieldwork is complex and costly with the finite risk. For the present study, 36 men and 32 women completed the Paffenbarger Physical Activity Index Questionnaire, including a sweat-inducing physical activity frequency question, and had measurement of oxygen uptake during pedal ergometry. Using maximal oxygen uptake as the measure of fitness, the Paffenbarger Physical Activity Index, although more detailed, may be less valid than the simpler sweat induction frequency question for estimating fitness. The correlations observed between the sweat question and oxygen uptake were 0.54 for males, 0.26 for females, and 0.46 for the total group. The correlations between the Physical Activity Index and oxygen uptake were 0.26 for males, 0.08 for females, and 0.29 for the total group. The regression relationship (oxygen uptake = 1.92 .times. (sweat days) + 23.76; standard error of estimate = 8.63 m;/kg/min) is significant for sweat vs. oxygen uptake. While the confidence interval limits the practical ability to predict individual values, low cost, absence of risk, and population validity suggest that fitness can be assessed rapidly and simply for epidemiologic studies with a simple sweat question.
