The purpose of the study was to establish standards for cardiopulmonary responses to exercise in healthy Chinese subjects in Taiwan. One hundred and five sedentary healthy subjects, 55 men and 50 women aged between 20 and 75 years, were tested. They pedalled a cycle ergometer with the work rate increased by 10 W every minute until they were exhausted. Expiratory gas volume, oxygen concentration, carbon dioxide concentration, and heart rate were measured during the exercise test. Work rate (WRmax), oxygen consumption (VO2max), oxygen consumption divided by body weight (VO2max/BW), heart rate (HRmax), and ventilation (VEmax) at maximal exercise, and oxygen consumption at anaerobic threshold (VO2AT) were determined. These parameters were regressed by age (A, in year), height (H, in cm), body weight (G, in kg), and gender (S, 0 = women, and 1 = men), and the following predictive equations were obtained: 1) WRmax (W) = -1.2 A + 1.1 H + 0.7 G + 28 S - 56, R = 0.90; 2) VO2max (ml/min) = -20 A + 9.5 H + 16 G + 461 S - 237, R = 0.90; (3) VO2max/BW (ml/kg/min) = -0.31 A + 0.14 H - 0.14 G - 7.2 S + 22, R = 0.87; 4) HRmax (beat/min) = -0.81 A + 209, R = 0.61; 5) VEmax (L/min) = -0.74 A - 0.04 H + 0.93 G + 22.2 S + 42, R = 0.83; 6) VO2AT (ml/min) = -9.5 A + 3.5 H + 9.4 G + 140 S - 122, R = 0.79. Our results provide normal standards for cardiopulmonary responses to exercise during cycle ergometer testing in Taiwan.
该研究的目的是建立台湾健康中国受试者运动心肺反应的标准。对105名久坐不动的健康受试者进行了测试，其中55名男性和50名女性，年龄在20至75岁之间。他们在自行车测力计上蹬踏，工作强度每分钟增加10W，直至精疲力竭。在运动测试期间测量呼气气体量、氧气浓度、二氧化碳浓度和心率。测定最大运动时的工作强度（WRmax）、耗氧量（VO2max）、耗氧量除以体重（VO2max/BW）、心率（HRmax）和通气量（VEmax），以及无氧阈时的耗氧量（VO2AT）。这些参数按年龄（A，岁）、身高（H，厘米）、体重（G，千克）和性别（S，0=女性，1=男性）进行回归分析，得到以下预测方程：1）WRmax（W）=-1.2A+1.1H+0.7G+28S-56，R=0.90；2）VO2max（毫升/分钟）=-20A+9.5H+16G+461S-237，R=0.90；（3）VO2max/BW（毫升/千克/分钟）=-0.31A+0.14H-0.14G-7.2S+22，R=0.87；4）HRmax（次/分钟）=-0.81A+209，R=0.61；5）VEmax（升/分钟）=-0.74A-0.04H+0.93G+22.2S+42，R=0.83；6）VO2AT（毫升/分钟）=-9.5A+3.5H+9.4G+140S-122，R=0.79。我们的研究结果为台湾自行车测力计测试期间运动心肺反应提供了正常标准。
