By thermometry in mixed venous blood the thermal reactions to exercise programmes of different durations were studied in healthy volunteers before and after smoking. Pulmonary oxygen uptake (V02), arterio-venous oxygen difference (AVD) and heart rate (HR) were also measured. It was found that exercise-induced rise in blood temperature was considerably augmented after smoking. This effect was parallelled (and probably partly caused) by an increased heat production reflected by increased V02. During short-term exercise an accelerated rise in AVD might indicate that a centripetal redistribution of the total blood flow could have contributed to the thermal response by a reduced skin blood flow. During long-term exercise cardiac output and heart rate increased and the stroke volume decreased in response to smoking.
通过测量混合静脉血的温度，研究了健康志愿者在吸烟前后对不同持续时间运动计划的热反应。还测量了肺摄氧量（V02）、动静脉氧差（AVD）和心率（HR）。结果发现，吸烟后运动引起的体温升高显著增加。这种效应与V02增加所反映的产热增加同时出现（可能部分是由其引起的）。在短期运动中，AVD加速上升可能表明总血流量向心性重新分布，通过减少皮肤血流量对热反应有贡献。在长期运动中，吸烟会导致心输出量和心率增加，而每搏输出量减少。
