The Acute Effects Of Nicotine And Exercise On Working Memory In Smokers, Matthew Fagan

Electronic Thesis and Dissertation Repository

Background: In a non-smoking population exercise and nicotine have been shown to increase cognition (Guirguis, 2016). In non-deprived smoking model it is unknown if the exercise will provide the same benefit seen in non-smokers.

Methods: A randomized counterbalanced crossover study design was utilized. The primary outcome was working memory accuracy and reaction time measured by n-back assessments (i.e., 3-back).

Results: A repeated measure ANOVA revealed a significant treatment effect for accuracy on the 3-back [F (24) = 8.118, p=.002, n²=.404]. Post-hoc paired sample t-tests uncovered a significant improvement in accuracy from baseline and the …

The Effect Of Exercise On Cravings And Ad Libitum Smoking Following Concurrent Stressors, Angela J. Fong

Electronic Thesis and Dissertation Repository

Quitting smoking itself is a stressor; it is likely that other stressors occur concurrently and deplete self-regulatory resources. Failure to cope leads to smoking relapse. Exercise has been shown to attenuate cravings and withdrawal symptoms in previous research and has yet to be examined following concurrent stressors. This study examined the effect of an acute bout of moderate intensity exercise on psychological withdrawal symptoms (PWS), cravings and ad lib smoking after concurrent stressors (i.e., temporary abstinence and depletion). Twenty-five smokers were randomized into exercise or passive conditions. Results showed PWS were significantly exacerbated after temporary abstinence and again after depletion …

The Effect Of An Acute Bout Of Exercise On Smoking Topography, Terri L. Schneider

Electronic Thesis and Dissertation Repository

This pilot study aimed to examine the effect of an acute bout of exercise on smoking behavior (topography) subsequent to a temporary period of smoking abstinence. Forty-three adult smokers (female = 34, M_age = 43.14), who had been smoking for an average of 23.90 years, were randomized to either an exercise (n = 21) or passive sitting group. Thirty-one smokers completed the study. The primary outcome variables included: puff count, puff volume, puff duration, inter-puff interval (IPI), and total cigarette duration. The effect of exercise on smoking topography was non-significant. Overall, the effectiveness of exercise as an additional …
