The influence of adiposity on physiological, perceptual, and affective responses during walking at a self-selected pace.
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.
