基本原理
戒烟期间，对吸烟相关线索的注意力偏差会增加，并且可以预测戒烟后的复发。研究发现，运动可以减少暂时戒烟期间对香烟的渴望和吸烟的欲望，并减弱对吸烟信号的反应而增加的渴望。
目标
评估运动对暂时戒烟期间吸烟相关线索的注意力偏差的急性影响。
方法
在随机交叉设计中，经常吸烟者 (n = 20) 在不同的日子进行 15 分钟的锻炼（中等强度的固定自行车）或在戒除 15 小时尼古丁后进行被动静坐。在基线和治疗后测量注意力偏差。使用 Eyelink II 眼动追踪系统被动观看一系列配对吸烟图像和中性图像期间，评估停留时间百分比和初始注视方向。在基线、治疗中期和治疗后以及眼动追踪任务后记录自我报告的吸烟欲望。
结果
吸烟欲望存在显着的条件 x 时间交互作用，F((1,18)) = 10.67，P = 0.004，eta(2) = 0.36，在运动条件下治疗中期和治疗后吸烟欲望显着降低。与被动控制相比，运动条件下对吸烟图像的停留时间百分比和初始注视方向也显着减少。
结论
研究结果支持了之前的研究，即剧烈运动会降低吸烟的欲望。这是第一项表明运动似乎也会影响对香烟的显着性和注意力偏差的研究。
RATIONALE
Attentional bias towards smoking-related cues is increased during abstinence and can predict relapse after quitting. Exercise has been found to reduce cigarette cravings and desire to smoke during temporary abstinence and attenuate increased cravings in response to smoking cues.
OBJECTIVE
To assess the acute effects of exercise on attentional bias to smoking-related cues during temporary abstinence from smoking.
METHOD
In a randomized cross-over design, on separate days regular smokers (n = 20) undertook 15 minutes of exercise (moderate intensity stationary cycling) or passive seating following 15 hours of nicotine abstinence. Attentional bias was measured at baseline and post-treatment. The percentage of dwell time and direction of initial fixation was assessed during the passive viewing of a series of paired smoking and neutral images using an Eyelink II eye-tracking system. Self-reported desire to smoke was recorded at baseline, mid- and post-treatment and post-eye-tracking task.
RESULTS
There was a significant condition x time interaction for desire to smoke, F((1,18)) = 10.67, P = 0.004, eta(2) = 0.36, with significantly lower desire to smoke at mid- and post-treatment following the exercise condition. The percentage of dwell time and direction of initial fixations towards smoking images were also reduced significantly following the exercise condition compared with the passive control.
CONCLUSION
Findings support previous research that acute exercise reduces desire to smoke. This is the first study to show that exercise appears to also influence the salience and attentional biases towards cigarettes.
