Recent research has shown that 10 min of moderate intensity exercise reduce smoking withdrawal symptoms and desire to smoke in acutely abstinent smokers. The aim of the current study was to determine whether the reductions are related to participant expectation of these effects.
Forty-five sedentary participants who had smoked ten or more cigarettes per day for at least 3 years reported their expectation of the effects of exercise on smoking withdrawal symptoms. Approximately 1 month later, participants were randomly assigned to one of three groups after 11-15 h of overnight smoking abstinence. Each group read either a positive, negative or neutral statement concerning exercise effects on smoking withdrawal symptoms. They rated their expectation again and then completed 10 min of moderate intensity exercise on a stationary bicycle ergometer. Using standardised scales, participants rated smoking withdrawal symptoms and desire to smoke at 10, 5 and 0 min before exercise, then at 5 and 10 min during exercise and 15 and 20 min post-exercise.
Expectation of exercise effects on withdrawal were manipulated in the predicted directions. No significant group main effects were found for any symptom. Significant reductions in symptoms and desire to smoke occurred during and after exercise regardless of participant expectation.
Ten minutes of moderate intensity exercise can lead to reductions in desire to smoke and smoking withdrawal symptoms, which are not due to the participant's expectation of exercise effects. These findings support the use of short periods of exercise as an aid to smoking cessation.
近期研究表明，10分钟的中等强度运动可减轻近期戒烟者的吸烟戒断症状及吸烟欲望。本研究旨在确定这些减轻效果是否与参与者对这些影响的预期有关。
45名久坐不动的参与者，他们每天吸烟10支或更多，且至少持续了3年，报告了他们对运动对吸烟戒断症状影响的预期。大约1个月后，在经过11 - 15小时的夜间戒烟后，参与者被随机分为三组。每组阅读一份关于运动对吸烟戒断症状影响的积极、消极或中性陈述。他们再次对预期进行评分，然后在固定自行车测力计上完成10分钟的中等强度运动。使用标准化量表，参与者在运动前10分钟、5分钟和0分钟，运动期间5分钟和10分钟，以及运动后15分钟和20分钟对吸烟戒断症状和吸烟欲望进行评分。
对运动对戒断影响的预期按预测方向进行了操控。未发现任何症状有显著的组间主效应。无论参与者的预期如何，运动期间及运动后症状和吸烟欲望均显著降低。
10分钟的中等强度运动可导致吸烟欲望和吸烟戒断症状降低，这并非由于参与者对运动效果的预期。这些发现支持将短时间运动作为戒烟辅助手段。
