The aim of this study was to compare acute affective responses at exercise intensities based on the ventilatory threshold between normal weight, overweight, and obese women. 66 sedentary women (22 in each Body Mass Index group) performed a maximal graded treadmill test to measure their maximal oxygen uptake and ventilatory thresholds. Affective valence was compared at intensities spanning the ventilatory threshold (below, at, and above threshold). Affective valence below ventilatory threshold did not differ among the Body Mass Index groups. The obese group had a lower affective response at ventilatory threshold and above ventilatory threshold than the normal weight and overweight groups; the latter two groups did not differ. The obese group had a lower affective response than the normal and overweight groups, which corresponds to a less pleasant experience. Exercise prescriptions for obese subjects targeting intensities below ventilatory threshold can provide a more pleasant experience and may facilitate exercise adherence.
本研究旨在比较基于通气阈的正常体重、超重和肥胖女性在不同运动强度下的急性情感反应。66 名久坐不动的女性（每个体重指数组 22 名）进行了最大递增跑步机测试，以测量她们的最大摄氧量和通气阈。在跨越通气阈（阈下、阈中和阈上）的强度上比较了情感效价。在通气阈以下，体重指数组之间的情感效价没有差异。肥胖组在通气阈和通气阈以上的情感反应低于正常体重组和超重组；后两组之间没有差异。肥胖组的情感反应低于正常体重组和超重组，这表明体验不那么愉快。针对通气阈以下强度的肥胖受试者的运动处方可以提供更愉快的体验，并可能促进运动坚持。
