Although an inverse correlation between physical activity and depression among adolescents has been found in research, this relation has seldom been examined prospectively. Thus, we tested whether physical activity reduces risk for future escalations in depression and whether depression decreases likelihood of future change in physical activity.
Data from a longitudinal study involving annual assessments of 496 adolescent girls (mean age = 13 years, SD = 0.73) followed over a 6-year period were analyzed to address these questions.
Using analyses that controlled for several covariates, we found that physical activity significantly reduced risk for future increases in depressive symptoms and risk for onset of major-minor depression. Further, depressive symptoms and major-minor depression significantly reduced future physical activity. However, predictive effects were modest for both.
Results support a bidirectional relation between exercise and depression and imply that interventions that increase physical activity may reduce risk for depression among this high-risk population.

    • "Additionally, in most of these studies the relevant variable depression was inconsistently considered. Although depressive symptoms is frequent in AN [23] and its inverse link to PA has been documented [4] [32] [53], previous studies have not taken it into account. The present study attempts to overcome some of the aforementioned methodological gaps by using an objective instrument to examine various types of PA with a continuous measure approach, in a partial Day Hospital treatment, which is less restrictive in terms of PA and is a more realistic setting, and after considering those factors that may be influencing both PA and treatment outcome (such as depression symptoms). "

    • "Low physical activity and cardiovascular fitness predict depressive disorder (Aberg et al., 2012; Mikkelsen et al., 2010). Longitudinal studies suggest that the relationship between physical activity and depression is bidirectional (Azevedo Da Silva et al., 2012; Jerstad et al., 2010). Meta-analyses show that physical exercise used as a therapeutic intervention may have moderate size effects on depressive symptoms (Cooney et al., 2013). "

    ABSTRACT: Major depressive disorder (MDD) is associated with decreased physical activity and increased rates of the metabolic syndrome (MetS), a risk factor for the development of type 2 diabetes and cardiovascular disorders. Exercise training has been shown to improve cardiorespiratory fitness and metabolic syndrome factors. Therefore, our study aimed at examining whether patients receiving an exercise program as an adjunct to inpatient treatment will benefit in terms of physiological and psychological factors. Fourty-two inpatients with moderate to severe depression were included. Twenty-two patients were randomized to additional 3x weekly exercise training (EXERCISE) and compared to treatment as usual (TAU). Exercise capacity was assessed as peak oxygen uptake (VO2peak), ventilatory anaerobic threshold (VAT) and workload expressed as Watts (W). Metabolic syndrome was defined according to NCEP ATPIII panel criteria. After 6 weeks of treatment, cardiorespiratory fitness (VO2peak, VAT, Watt), waist circumference and HDL cholesterol were significantly improved in EXERCISE participants. Treatment response expressed as ≥50% MADRS reduction was more frequent in the EXERCISE group. Adjunctive exercise training in depressed inpatients improves physical fitness, MetS factors, and psychological outcome. Given the association of depression with cardiometablic disorders, exercise training is recommended as an adjunct to standard antidepressant treatment. Copyright © 2015 Elsevier B.V.

    • "Further, depression symptoms often include motor delay and low energy, both of which may affect the ability to engage in PA (Jerstad et al., 2010). There has been indirect evidence from longitudinal studies to support these associations (Brunet et al., 2013; Jerstad et al., 2010). Little is known about mechanisms that may underpin the association between depression and PA. "

    ABSTRACT: Objective: To test if motivational regulations (i.e., amotivation, external, introjected, identified, and intrinsic) mediate the association between depression symptoms and moderate-to-vigorous physical activity (MVPA) in young adults. Method: A total of 319 young adults from Montreal, Quebec participating in the Nicotine Dependence in Teens (NDIT) study provided self-report data on depression symptoms at age 20 (SD=0.7 years) and motivational regulations at age 24 (SD=0.7 years). MVPA was assessed using a self-report questionnaire at age 20 (i.e., at the same time motivation was measured) and using accelerometers one month later. Multiple mediation analysis with bootstrapping was employed to analyze the data. Results: Controlling for age, sex and self-reported MVPA at age 20 years; introjected regulation was a significant mediator of the association between depression symptoms and MVPA (R(2) adj=0.12; point estimate=-0.0011; BCa CI=-0.15 to -0.01). Conclusion: Depression symptoms may undermine controlling forms of motivation, resulting in decreased MVPA. Intervention strategies may be needed to address depression symptoms in young adults to promote sustained MVPA.
