Exploring motivation for exercise and its relationship with health-related quality of life in adults aged 70 years and older

Abstract

ABSTRACTThe health benefits of regular exercise participation have been widely acknowledged. Drawing upon self-determination theory, the purpose of our study was to identify the motivational profiles for exercise among older adults aged 70 years and older who regularly participated in sporting programmes, and to relate the motivational profiles to health-related quality of life measures (HRQoL). A random sample of 100 older adults (mean age = 75.34 years, standard deviation = 4.89; 57 women and 43 men) belonging to French sports clubs was recruited for the aim of the study. Participants completed a survey including measures of motivation and health-related quality of life, and socio-demographic and health variables. Cluster analyses revealed two distinct motivational profiles among participants: ‘highly self-determined’ (high levels of self-determined motivation and introjected regulation as well as low levels of external regulation and amotivation), and ‘moderately introjected’ (low levels of self-determined motivation, moderate level of introjected regulation and low levels of external regulation and amotivation). Multivariate analysis of covariance (MANCOVA) results revealed that the most self-determined group reported significantly higher values in four domains of HRQoL, namely role limitations due to physical health, bodily pain, social functioning and role limitations due to emotional health (p = 0.01). These data suggest the importance of taking into account the motivational perspective and considering exercise maintenance among older adults as an important public health challenge.
