Research has shown that acute exercise reduces urges for chocolate in normal weight people. This study aimed to examine the effects of an acute exercise bout on urges to consume sugary snacks, affect as well as 'psychological and physiological responses' to stress and a 'sugary snack cue', in overweight individuals. Following 3 days of chocolate-abstinence, 47 overweight, sugary snack consumers were assessed, in 2 randomly ordered conditions, in a within-subject design: 15-min brisk walk or passive control. Following each, participants completed 2 tasks: Stroop color-word interference task, and handling sugary snacks. Urges for sugary snacks, affective activation and valence were assessed. ANOVAs revealed significant condition x time interaction effects for: urges to consume sugary snacks, affective valence and activation. Obtained data show that exercise reduces urges for sugary snacks and attenuates urges in response to the stress situation and the cue in overweight people.
研究表明，急性运动可降低正常体重人群对巧克力的渴望。本研究旨在探讨一次急性运动对超重个体食用含糖零食的渴望、情绪以及对压力和“含糖零食提示”的“心理和生理反应”的影响。在3天不食用巧克力之后，对47名超重的含糖零食消费者进行评估，采用受试者内设计，在两种随机排序的条件下进行：15分钟的快走或被动对照。每次之后，参与者完成两项任务：斯特鲁普颜色-文字干扰任务和处理含糖零食。评估对含糖零食的渴望、情感激活和效价。方差分析显示，在以下方面存在显著的条件×时间交互效应：食用含糖零食的渴望、情感效价和激活。所得数据表明，运动可降低超重人群对含糖零食的渴望，并减轻对压力情境和提示的渴望。
