Document Summary

Study: effects of exercise training on older patients with major depression. Extent to which exercise training may reduce depressive symptoms in older patients with major depressive disorder (mdd) has not been systematically evaluated. To assess effectiveness of an aerobic exercise program compared to standard antidepressants. Stepwise reduction effect over time: pooled standardize mean difference (smd) Demystifying the shrinkage phenomenon: applying the following rule to the data: only examine studies where exercise is compared to a non-exercise control pooled smd is raised form-0. 62 to -0. 90 (increase smd) Depression is associated with low efficacious beliefs: low confidence in ability to achieve valued outcomes, low confidence in ability to regulate negative cognition, low confidence in ability to cope. Implications in reduction in hippocampal volume and high cortisol secretion. If exercise is an efficacious treatment, it may do the same thing: exercise has been shown to improve episodic memory in healthy young adults. In those with depression cortisol secretion normalized with successful treatment.
