对于超重/肥胖的个体，内化体重偏差（IWB）与低体力活动（PA）有关。本研究使用基于实验室的范例来检验IWB调节PA期间心率（HR）与感知的劳累和情感之间的关联的假设。超重/肥胖的参与者完成了30分钟有监督的中等强度跑步机行走（年龄预测最大HR的65%-75%）。在基线时评估体重指数（BMI）和体重偏倚内化量表。每分钟监测一次HR;每5分钟评估一次自感劳累和情感。采用线性混合模型，时间和参与者的随机效应。样本（n = 59; 79.7%女性，91.5%白色）的平均BMI = 32.1 kg/m2（SD：3.3），年龄= 47.1（SD：10.3）岁。IWB对感知的消耗有主要影响（IWB越大，运动期间感知的消耗越大; p < 0.001）。IWB和HR在情感上存在交互作用（B =-0.01，p < 0.01）。对于高IWB的个体，HR升高与运动期间的负性情感反应相关。对于低IWB的个体，HR升高与PA期间积极影响的增加相关。研究结果表明，在较高的体重的个人，IWB与报告较高的感知消耗在30分钟的中等强度PA。IWB调节运动期间HR增加与情感之间的关系。在报告IWB的超重/肥胖个体中，PA的初始体验可能更难，更不愉快，对PA的采用具有持久的影响。
For individuals with overweight/obesity, internalized weight bias (IWB) is linked to low physical activity (PA). This study used a laboratory‐based paradigm to test the hypothesis that IWB moderates the association between heart rate (HR) and perceived exertion and affect during PA. Participants with overweight/obesity completed 30‐min of supervised moderate‐intensity treadmill walking (65%–75% of age‐predicted maximal HR). Body Mass Index (BMI) and Weight Bias Internalization Scale were assessed at baseline. HR was monitored every minute; perceived exertion and affect were assessed every 5 min. Linear mixed models were employed with random effects of time and participant. The sample (n = 59; 79.7% female, 91.5% white) had an average BMI = 32.1 kg/m2 (SD: 3.3), and age = 47.1 (SD: 10.3) years. There was a main effect of IWB on perceived exertion (greater IWB was associated with greater perceived exertion during exercise; p < 0.001). There was an interaction of IWB and HR on affect (B = −0.01, p < 0.01). For individuals with high IWB, HR elevations were associated with a negative affective response during exercise. For individuals with low IWB, HR elevations were associated with increased positive affect during PA. Findings indicate that among individuals of higher body weight, IWB is associated with reporting higher perceived exertion during 30 min of moderate intensity PA. IWB moderated the relationship between increasing HR during exercise and affect. Among individuals with overweight/obesity who report IWB, the initial experience of PA may be harder and more unpleasant, with lasting implications for the adoption of PA.
