My research will use a mixed methods approach to explore women’s experiences and health care professionals’ experiences of physical activity throughout pregnancy and motherhood. These experiences will involve different cultural perspectives and how support (or a lack of) is provided for these women. Psychological and sociological theoretical frameworks will be applied to support my research, including the self-determination meta-theory (Ryan and Deci, 2000), psychological empowerment (e.,g Zimmerman, 1995), and theories of fear (judgement, harm). This research will be a foundation for future interventions, knowledge exchange event, podcasts and mainstream dissemination, to improve culturally diverse mothers’ wellbeing and identify appropriate physical activity for their needs, health, culture and lifestyle.
