          Abstract

          ABSTRACT 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.

          RESUMEN La investigación indica que la actividad física se asocia con una menor percepción de estrés y agotamiento emocional. La literatura reciente muestra que la actividad física aeróbica habitual de intensidad vigorosa (AFV) puede tener efectos provechosos que pueden ir bastante más allá que los de la actividad física aeróbica habitual de intensidad moderada (AFM). No obstante, hay pocos estudios que investiguen los papeles enfrentados de la AFV y la AFM en condiciones de trabajo adversas. A partir de los datos de un estudio online realizado con 847 empleados pusimos a prueba si la AFV y la AFM tienen relación con síntomas menores de agotamiento emocional y si modulan la relación de las exigencias del puesto de trabajo y el agotamiento laboral. Los resultados señalan un efecto principal negativo entre la AFM y el agotamiento emocional, pero ninguno entre este y la AFV. Sin embargo, los resultados indican que la AFV modera la relación nociva de las exigencias elevadas del puesto de trabajo con el agotamiento emocional. Los hallazgos indican que los empleados pueden sacar provecho de la AFM con independencia del nivel de exigencia del puesto mientras que la AFV puede además ayudar a manejar un elevado nivel de exigencia.

            Job demands–resources theory: Taking stock and looking forward.

            The job demands-resources (JD-R) model was introduced in the international literature 15 years ago (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). The model has been applied in thousands of organizations and has inspired hundreds of empirical articles, including 1 of the most downloaded articles of the Journal of Occupational Health Psychology (Bakker, Demerouti, & Euwema, 2005). This article provides evidence for the buffering role of various job resources on the impact of various job demands on burnout. In the present article, we look back on the first 10 years of the JD-R model (2001-2010), and discuss how the model matured into JD-R theory (2011-2016). Moreover, we look at the future of the theory and outline which new issues in JD-R theory are worthwhile of investigation. We also discuss practical applications. It is our hope that JD-R theory will continue to inspire researchers and practitioners who want to promote employee well-being and effective organizational functioning. (PsycINFO Database Record

              A neurotrophic model for stress-related mood disorders.

              There is a growing body of evidence demonstrating that stress decreases the expression of brain-derived neurotrophic factor (BDNF) in limbic structures that control mood and that antidepressant treatment reverses or blocks the effects of stress. Decreased levels of BDNF, as well as other neurotrophic factors, could contribute to the atrophy of certain limbic structures, including the hippocampus and prefrontal cortex that has been observed in depressed subjects. Conversely, the neurotrophic actions of antidepressants could reverse neuronal atrophy and cell loss and thereby contribute to the therapeutic actions of these treatments. This review provides a critical examination of the neurotrophic hypothesis of depression that has evolved from this work, including analysis of preclinical cellular (adult neurogenesis) and behavioral models of depression and antidepressant actions, as well as clinical neuroimaging and postmortem studies. Although there are some limitations, the results of these studies are consistent with the hypothesis that decreased expression of BDNF and possibly other growth factors contributes to depression and that upregulation of BDNF plays a role in the actions of antidepressant treatment.
