Purpose: To investigate the associations of physical performance with positive and negative dimensions of mental well-being in middle-aged women and explore the role of physical activity (PA) in these associations.
Methods: Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n=909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule Short Form and the Satisfaction with Life Scale) and PA were self-reported. Associations between variables were analysed using multivariate linear regression modelling adjusted for body height, fat mass %, menopausal status and symptoms, marital status, parity, employment status, self-reported mental disorders, and use of psycholeptics and psychoanaleptics. PA was then entered into a separate model to explore its role in the associations.
Results: In the adjusted models, significant positive associations of six-minute walking distance with positive affectivity (B=0.12, p=0.002) and life satisfaction (B=0.15, p=0.033) were observed. No significant associations were observed between physical performance and depressive symptoms or negative affectivity. PA was positively associated with positive affectivity and life satisfaction and negatively with depressive symptoms across all the physical performance variables.
Conclusion: The results point to the benefits of physical activity for mental well-being. However, in addition to PA, of the physical performance measures, the aerobic component of physical performance is especially beneficial for positive mental well-being in middle-aged women.
