Abstract

Well-being and engagement in the workplace have declined in recent years, although they have a critical role in organisational productivity and retention. While the Job-Demands (JD-R) model emphasizes both job and personal resources as drivers of engagement, there is less research exploring ways in which employees can cultivate their own engagement through modifiable behaviours such as physical activity. This study addresses that gap, through investigating whether physical activity predicts higher job engagement. Additionally we analyse whether strain mediates this relationship, and finally, if physical activity intensity moderates these effects. To test this, a cross-sectional study was conducted, where a survey of 107 employed adults measured physical activity frequency/intensity, job engagement, and strain. Results showed no significant support for a direct positive association between physical activity and engagement and no significant support was found for strain as a mediator and physical activity intensity as a moderator, highlighting the importance of alternative pathways toward engagement. The study’s limited statistical power highlights the need for testing with larger samples. Future research could explore this alongside additional potential mediators, and objective activity measures to clarify these relationships.
