Background: Cigarette cravings are one of the most often expressed difficulties related to quitting. The effect of acute exercise on craving and withdrawal symptoms during a pharmacological based smoking cessation intervention is unknown. Methods: Participants included female smokers (n = 178) undertaking the Getting Physical on Cigarettes trial — a 14-week exercise-aided nicotine replacement therapy (NRT, i.e. patch) cessation program. They completed the Shiffman-Jarvik scale immediately before and after the first scheduled exercise session during weeks 5, 11, and 13. The first exercise session (week 5) occurred shortly after participants quit smoking (week 4) and began their 21 mg NRT patch dose. The second and third exercise bout coincided soon after participants stepped down their NRT strength to 14 mg (week 11) and 7 mg (week 13), respectively. Results: Significant reductions in cigarette craving were demonstrated following exercise at all three time points (i.e. week 5, 11, and 13). Significant reductions in psychological and sedation withdrawal symptoms were shown at week 5 and 11, but not at week 13. Significant increases in physical symptoms were found at week 5 and 11, but not week 13. No significant change in appetite was evident at any time point. Conclusions: An acute bout of moderate intensity exercise can alleviate cravings as well as psychological and sedation withdrawal symptoms in quitters during a 14-week exercise-aided NRT smoking cessation program. Promoting exercise among women using NRT is recommended.

Research consistently demonstrates that a bout of moderate exercise alleviates cravings to smoke among abstaining smokers. This pilot study examined the effects of an acute bout of brisk walking on cigarette cravings and smoking topography. Using a within-subject, crossover design, two 10-minute treatment sessions were conducted on separate days by 19 participants (M age = 24.6 years): passive (i.e., sitting) and brisk walking conditions. Participants rated cravings at baseline, midcondition, and at 0-, 10-, and 20-minutes postcondition and objective measures of smoking topography (puff count, puff duration, puff volume, interpuff interval [IPI], time to first puff [TTFP]) were obtained with the first cigarette smoked postcondition. A 2 (condition) × 4 (time) ANCOVA indicated lower desire to smoke (p < .05) during the walking condition than the passive condition. After the brisk walking condition, a series of ANOVAs demonstrated a significantly increased delay to first puff in comparison to the passive condition. Posthoc analyses (controlling for abstinence period) indicated significant lower puff volume and a trend for shorter puff duration following brisk walking in comparison to the passive sitting condition. A greater reduction in cravings was associated with a longer delay to first puff. In addition to reducing cravings, these results suggest that a bout of brisk walking may also change an individual's smoking behaviour.
