Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus
Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus
Electronic Thesis and Dissertation Repository
Cigarette smoking is a leading agent for premature morbidity and mortality among the global community. Most individuals surrender to tobacco use disorder due to the inability to cope with cravings and withdrawal symptoms. Exercise appears to provide acute relief. Currently, it is unclear how exercise attenuates these reductions. Furthermore, the available evidence has focused on acute outcomes besides smoking behaviour and is limited to simulated quit attempts. Three experimental studies were designed to address these outstanding issues. Not surprisingly, a bout of moderate intensity exercise was found in study 1 (chapter 2) to reduce cravings associated with a temporary period …
The Use Of Exercise Self-Talk By Female Adolescents, Sadie Puddister
The Use Of Exercise Self-Talk By Female Adolescents, Sadie Puddister
Electronic Thesis and Dissertation Repository
Already below recommended levels, physical activity participation in female youth is known to decline throughout adolescence. Self-talk, a form of self-regulation has been demonstrated to influence behaviour in both sport and exercise settings. The purpose of the present research was to explore the exercise related self-talk of teen girls (aged 14-18) with the intent of uncovering reoccurring themes and attributes in the self-talk of both low frequency exercisers (LFEs) and high frequency exercisers (HFEs). Participants were teen girls (N=28, Mage=15.56, SDage=1.47) recruited from A. B. Lucas Secondary School in London, Ontario. Physical activity …

Stress associated psychiatric disorders such as depression, anxiety, and post-traumatic stress disorder affect a large proportion of the population. Reductions in the complexity of neuronal morphology and reduced neurogenesis are commonly observed outcomes following stress exposure in rodent models and may represent a mechanism for the reduced brain volume in stress sensitive regions such as the hippocampus observed in individuals diagnosed with stress associated disorders. Multiple lines of evidence suggest that glycogen synthase kinase (GSK)-B may play a role in the neurodegenerative phenotype observed following stress exposure. GSK3B is atypical in that it is inhibited by phosphorylation. This inhibitory phosphorylation …
Exercise Motivations Of Older Adults, Laura J. Attaway
Exercise Motivations Of Older Adults, Laura J. Attaway
All Master's Theses
This study examined and compared activity levels and motives in 103 older (over 50 years of age) competitive athletes (CA) and non-competitive fitness exercisers (NCF). The findings indicate that the CA group was significantly higher in the motives of enjoyment, competition, and social recognition. Ranking of the strength of the motivation factors for each group indicated that enjoyment was the strongest motivating factor for both groups, health ranked high for both groups, and social recognition ranked lowest in both groups. Findings related to rankings were not tested for significance, so are more tentative.
