Abstract

Ventilatory responses to submaximal exercise loads indicate that in a population of 895 physically active and sedentary male and female subjects, exercise ventilation is inversely related to predicted VO2max. The correlation coefficients for males and females in this relationship are 0.61 (P less than 0.0001) and 0.26 (P less than 0.0001) respectively. The slopes of regression lines for VE/VO2 and VO2max in female and male subjects are -2.59 and -0.91 respectively. This is associated with changes in composition of the expired air in that PCO2 increases and PO2 decreases with greater VO2max. The difference between the mean oxygen and carbon dioxide partial pressures in expired air of individuals in the highest and lowest VO2max ranges are 1.2 kPa (9 mm Hg) and 0.8 kPa (6 mm Hg) respectively.

摘要

对亚最大运动负荷的通气反应表明，在895名有体育活动和久坐的男性及女性受试者群体中，运动通气与预测的最大摄氧量呈负相关。在这种关系中，男性和女性的相关系数分别为0.61（P<0.0001）和0.26（P<0.0001）。女性和男性受试者中VE/VO2与最大摄氧量的回归线斜率分别为-2.59和-0.91。这与呼出气体成分的变化有关，即随着最大摄氧量增加，二氧化碳分压升高，氧分压降低。在最大摄氧量最高和最低范围内的个体，呼出气体中平均氧分压和二氧化碳分压的差值分别为1.2 kPa（9 mmHg）和0.8 kPa（6 mmHg）。
