有证据表明，锻炼/减肥电视对锻炼的明确态度有负面影响。然而，目前还不清楚这是特定于观看剧烈运动或超重/肥胖状态的观看锻炼者。此外，暴露于运动提示可以诱导人们吃得更多，反映了对运动提示而不是实际运动的补偿性饮食。在这项研究中，我们研究了超重/肥胖与正常体重锻炼者对饮食（卡路里消耗）和锻炼态度的相对影响。102名大学生被随机观看：1）超重/肥胖个体参与剧烈运动; 2）正常体重个体参与剧烈运动;或3）与各种体重状态的参与者的无运动视频（对照条件）。参与者随后完成了一项评估卡路里消耗的味觉测试;一项计算机化的内隐运动态度任务;以及一份明确的运动态度问卷。具有较高BMI的参与者和那些观察正常体重锻炼者（与超重/肥胖锻炼者相比）的参与者吃得更多。BMI和视频之间的相互作用或对运动的外显或内隐态度没有显着影响。这项研究扩展了观察剧烈运动对饮食行为的影响的发现。如果在自然条件下复制，研究结果对健康促进举措和影响暴饮暴食的电视节目有影响。
Evidence exists for a negative influence of exercise/weight-loss television on explicit attitudes towards exercise. However, it is unclear if this is specific to viewing intense exercise or the overweight/obese status of the viewed exercisers. Additionally, exposure to exercise cues can induce people to eat more, reflecting compensatory eating in response to exercise cues rather than actual exercise. In this study, we examined the relative influence of viewing overweight/obese versus normal weight exercisers on eating (calories consumed) and attitudes towards exercise. 102 college students were randomized to view: 1) overweight/obese individuals engaging in vigorous exercise; 2) normal weight individuals engaging in vigorous exercise; or 3) no-exercise video with participants of various weight statuses (control condition). Participants subsequently completed a taste test assessing calories consumed; a computerized, implicit attitudes-towards-exercise task; and an explicit attitudes-towards-exercise questionnaire. Participants with higher BMIs and those viewing normal weight exercisers (vs. overweight/obese exercisers) ate significantly more. No significant effects were found for the interaction between BMI and video or for explicit or implicit attitudes towards exercise. This study extends findings of the impact of viewing vigorous exercise to eating behaviors. If replicated under naturalistic conditions, findings have implications for health promotion initiatives and television programming impacting overeating.
