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

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, M_age=15.56, SD_age=1.47) recruited from A. B. Lucas Secondary School in London, Ontario. Physical activity …

An Examination Of Psychological Variables Influencing Perceptions Of The Self Among A Sample Of Female Exercise Initiates, Lisa Cooke

Electronic Thesis and Dissertation Repository

The general purpose of this dissertation was to explore the relationship among and within cognitive variables associated with exercise initiation and maintenance in a sample of female exercise initiates.

Manuscript 1 was structured to explore the changes to exercise identity among a population of female exercise initiates (N = 78) grouped into an imagery or control condition. Previous research has found that a strong exercise identity is associated with more frequent exercise (Strachan et al., 2009) and increases over time as a person continues to exercise (Cardinal & Cardinal, 1997). Participants were assessed multiple times (weeks 0, 5, 9, …

Mixed Methods Pilot Study Of Peri-Diagnostic Exercise Behaviour Change Among Women With Suspected Breast Cancer, Amy L. Deckert

Electronic Thesis and Dissertation Repository

Approximately 1 in 9 Canadian women will develop breast cancer in their lifetime (CCS, 2013). Over the past 30 years, population-based screening programs have contributed to decreased mortality rates (CCS, 2013), however the psychosocial sequelae associated with screening for breast cancer cannot be ignored (Holland et al., 2010). Although the majority of women screened will receive a benign diagnosis, the threat of malignancy can induce elevated levels of distress (Andrykowski et al., 2002).

We conducted a mixed methods pilot study to assess the feasibility and acceptability of a 6-week self-managed exercise behaviour change intervention to attenuate distress in women with …
