Aerobic capacity (VO2max) and lung capacities were measured in 66 healthy females ranging in age from 13 to 49 years. Forced vital capacity (FVC) and peak expiratory flow rate (PEFR) were measured using a dry spirometer and Wrights peak flow meter respectively. Cardiopulmonary parameters were obtained from a progressive ergocycle test to exhaustion. Mean FVC and PEFR obtained were 2.73 +/- 0.07 L and 412 +/- 8.5 L/min respectively. FVC correlated negatively with age in subjects from the 3rd to 5th decade of age (r = 0.38, p < 0.05). Mean VO2max was 43.2 +/- 0.9 ml/kg/min in the 2nd decade compared to 30.3 +/- 0.7 ml/kg/min in the fifth decade. Regression analysis revealed an age related decline in VO2max of 0.45 +/- 0.8 ml/kg/min/year, which was found to be somewhat higher compared to other studies.
对66名年龄在13至49岁之间的健康女性进行了有氧能力（最大摄氧量）和肺容量测量。分别使用干式肺活量计和赖特峰值流量计测量用力肺活量（FVC）和呼气峰值流速（PEFR）。通过进行递增式测力计测试直至力竭来获取心肺参数。测得的平均FVC和PEFR分别为2.73±0.07升和412±8.5升/分钟。在年龄处于第三个至第五个十年的受试者中，FVC与年龄呈负相关（r = 0.38，p < 0.05）。第二个十年的平均最大摄氧量为43.2±0.9毫升/千克/分钟，而第五个十年为30.3±0.7毫升/千克/分钟。回归分析显示，最大摄氧量随年龄的下降为每年0.45±0.8毫升/千克/分钟，这一数值相较于其他研究结果略高。
