FODOR, Daniel P et al. Intensity matters: the role of physical activity in the job demands-resources model. Rev. psicol. trab. organ. [online]. 2020, vol.36, n.3, pp.223-229.  Epub 11-Ene-2021. ISSN 2174-0534.  https://dx.doi.org/10.5093/jwop2020a21.

Research indicates that physical activity is associated with lower perceived job stress and burnout. Recent literature shows that regular vigorous-intensity aerobic physical activity (VPA) may have beneficial effects going well beyond those of regular moderate-intensity aerobic physical activity (MPA). However, research investigating the competing roles of VPA and MPA in the context of deleterious job conditions is scarce. Using data from an online-study with 847 employees, we tested if VPA and MPA relate to lower symptoms of burnout and whether they moderate the relationship of job demands and burnout. Results point towards a negative main effect between MPA and burnout whereas no main effect has been found between VPA and burnout. However, results indicate that VPA moderates the deleterious relationship of high job demands and burnout. Findings suggest that employees may benefit from MPA independently from level of job demand whereas VPA may additionally help coping with high job demands.
