The aim of this study was to investigate the influence of adiposity (% body fat) on physiological, perceptual, and affective responses during walking. 45 women were divided into low, medium, and high tertiles according to % body fat. Each participant completed a maximal exercise test and a 20-min. bout of walking at a self-selected pace. The preferred walking speed was similar among groups, whereas %VO2 max was greater in the high tertile group compared with the other two groups. Nevertheless, perceptual and affective responses were similar between the groups. These findings suggest that physiological responses relative to maximal capacity, but not perceptual and affective responses, of sedentary women are influenced by adiposity during walking at a self-selected pace. However, when the physiological responses are relative to ventilatory threshold, there are no differences between individuals with different levels of adiposity.
本研究的目的是调查肥胖程度（体脂百分比）对步行过程中的生理、感知和情感反应的影响。45名女性根据体脂百分比被分为低、中、高三分位数组。每位参与者都完成了一次最大运动测试以及一次以自选速度进行的20分钟步行。各组之间的首选步行速度相似，而高三分位数组的最大摄氧量百分比高于其他两组。然而，各组之间的感知和情感反应相似。这些发现表明，久坐不动的女性在以自选速度步行时，相对于最大能力的生理反应会受到肥胖程度的影响，但感知和情感反应不受影响。然而，当生理反应相对于通气阈值时，不同肥胖程度的个体之间没有差异。
