以前有报道称，超重和肥胖的人认为运动比他们的瘦同伴更困难，这种差异可能不仅仅归因于生理差异。因此，我们测试的假设，在运动过程中的运动难度的感知，独立于同时测量的生理指标的努力，预测体重反弹，完成减肥计划后的个体差异。113名先前完成减肥计划以达到正常体重（BMI <25）的超重女性接受了次最大有氧运动任务，同时记录了生理和感知消耗（RPE）的测量结果。在随后的1年自由生活期后评估体重增加。干预后1年的平均体重恢复为5.46 ± 3.95 kg。在回归模型中，RPE（β = 0.21，P = 0.01），而不是生理运动（β = 0.02，P = 0.81）与绝经前妇女体重减轻后1年的体重恢复呈正相关，与测量的混杂变量无关。RPE和体重恢复之间的关联表明，运动难度的感知是减肥干预后体重恢复的重要预测因素。
It has been previously reported that overweight and obese individuals perceive exercise as more difficult than their lean counterparts, and this difference may not be solely attributed to physiological differences. Therefore, we tested the hypothesis that individual differences in the perception of exercise difficulty during exercise, independent of concurrently measured physiological markers of exertion, are predictive of weight regain, after completion of a weight loss program. One-hundred and thirteen formerly overweight women who had previously completed a weight loss program to achieve a normal body weight (BMI <25) underwent a sub-maximal aerobic exercise task while measures of physiological and perceived exertion (RPE) were recorded. Weight gain was assessed following a subsequent 1-year free-living period. Average weight regain 1 year following the intervention was 5.46 ± 3.95 kg. In regression modeling, RPE (β = 0.21, P = 0.01), but not physiological exertion (β = 0.02, P = 0.81) was positively associated with 1-year weight regain following weight loss in premenopausal women, independent of measured confounding variables. The association between RPE and weight regain suggests that perception of exercise difficulty is an important predictor of weight regain following a weight loss intervention.
