Abstract

This thesis examines several of the propositions of Self-Determination Theory (SDT; Deci & Ryan, 1985) in the exercise domain. Utilising cross-sectional, longitudinal and experimental methodologies, the studies incorporated examine SDT’s potential to explain adaptive and maladaptive exercise engagement, cognitive and affective responses to group exercise across divergent ethnic groups, and adherence to an exercise on prescription scheme among obese patients attempting to facilitate weight loss. Moreover, this thesis examines the effects of an intervention aiming to train an exercise instructor to teach in accordance with SDT’s theoretical tenets. Collectively, the findings substantiate the applicability of SDT within the exercise domain. Although the importance of different SDT constructs vary in accordance with the outcome variable and type of exerciser being considered, in general, the socio-contextual facets proposed by SDT to foster psychological need satisfaction are supported in the exercise setting. Moreover, the socio-contextual factors and the psychological needs are shown to facilitate autonomous regulatory styles. The social-contextual variables, psychological needs, and autonomous forms of motivation also engender advantageous exercise-related behavioural, cognitive and affective responses to exercise, in addition to the promotion of indices of global well-being. Further, this research demonstrates that the socio-contextual characteristics advanced by SDT are amenable to manipulation, and reveals the potential utility of SDT to shape behavioural interventions targeting the promotion of physically active lifestyles and adaptive exercise experiences.
