A theoretical investigation of the development of physical activity habits in retirement

Objectives. This study examined the impact of retirement on physical activity (PA) patterns. More specifically, the process of initiating and maintaining behaviour changes in PA were explored using a self-determination theory perspective. Design. Semi-structured interviews were conducted to explore the formation of lifestyle habits post-retirement, and the role of PA within these. Interviews were analysed using thematic analysis and an informal comparison made between physically active and inactive retired adults. Methods. A total of 11 participants (7 female, 4 male; 6 physically active, 5 physically inactive) were recruited from churches and a local newspaper advertisement in South West England. On average, participants (M age 62.91 years; SD 2.3) had been retired 2 years and 8 months (SD 20.03). Results. Three main themes emerged from the interviews specific to retired adults; social factors, lifelong tendencies, and sense of purpose. All retired adults searched for purpose in their lives, and for physically active adults having an exercise schedule contributed to this on a daily basis. PA also represented a source of personal challenge, whereas physically inactive retirees sought meaning and challenge from non-exercise domains. All participants were acutely aware of their mortality, but active participants felt that PA would increase their chances of enjoying a healthy retirement, rather than accepting a decline in physical function. Conclusions. The results highlighted how global aspirations for life after retirement can influence one's post-retirement lifestyle. The implications for future research and potential health promotion approaches are discussed.
