The present study examines the possibility that the reduced activity commonly found in obese individuals could stem from a reduced physiological responsiveness to exercise. Responses to bicycle ergometer exercise (300 kpm/min) of four obese and four normal weight women were observed in a metabolic ward. This resulted in decreases in exercise heart rate and oxygen consumption, indicating an improvement in mechanical efficiency and suggesting an increase in physical working capacity. It also resulted in some decreases of resting oral temperature. The differences in the response to exercise between the obese and the normal weight groups were small and not statistically significant. The normal weight subjects showed a trend for greater decreases in heart rate and O2 consumption during exercise, while in the obese resting oral temperature tended to be more reduced. The results suggest that obesity in our subjects was not related to a deranged physiological response to physical activity.
本研究探讨了肥胖个体中常见的活动减少可能源于对运动的生理反应性降低这一可能性。在代谢病房观察了四名肥胖女性和四名正常体重女性对自行车测力计运动（300千帕米/分钟）的反应。这导致运动心率和耗氧量降低，表明机械效率提高，提示体力工作能力增加。同时也导致静息口腔温度有所下降。肥胖组和正常体重组对运动的反应差异较小，且无统计学意义。正常体重受试者在运动期间心率和耗氧量下降幅度更大，而肥胖者静息口腔温度下降幅度往往更大。结果表明，我们研究中的肥胖与对身体活动的生理反应紊乱无关。
