Several cardiopulmonary items were measured in eight adult females who had performed stationary ergometer cycling of 75-450 kgm/min in air temperature between 14 degrees and 35 degreesC. The experiments were designed on the basis of the Latin square method and the results were analyzed by computing the analysis of variance and multiple regression equations for each item linked with work rate and air temperature. In view of the degree of affinity of the effect of work rate and that of air temperature, the items could be divided into three groups. The first group consisted of items of pulmonary functions closely related with work rate but independent of air temperature, such as pulmonary ventilation, oxygen intake, carbon dioxide production, respiratory exchange ratio, and ratio of oxygen removal. The second group characterized by linear dependency on air temperature included mean skin temperature and mean innermost air temperature. The third group consisting of heart rate, pulse sum during work, and work pulse sum was intermediate. In spite of the confusion in the literature about the attitude of oxygen intake or mean skin temperature during work in heat, the former was the most stable in relation to change in air temperature and the latter was independent of work intensity.
在8名成年女性身上测量了几项心肺指标，她们在气温为14摄氏度至35摄氏度的环境中，以75 - 450千克米/分钟的强度进行了固定测力计骑行。实验采用拉丁方设计方法，通过计算方差分析和每个指标与工作强度及气温相关的多元回归方程来分析结果。鉴于工作强度和气温影响的关联程度，这些指标可分为三组。第一组包括与工作强度密切相关但与气温无关的肺功能指标，如肺通气量、摄氧量、二氧化碳产生量、呼吸交换率和氧摄取率。第二组指标包括平均皮肤温度和平均最内层空气温度，其特点是与气温呈线性相关。第三组由心率、工作期间脉搏总和以及工作脉搏总和组成，处于中间状态。尽管文献中对于炎热环境下工作时摄氧量或平均皮肤温度的情况存在混淆，但前者在气温变化方面最为稳定，而后者与工作强度无关。
