Effects of an acute maximal exercise bout on serum insulin-like growth factor-1 in adults with MDD.

Exercise has acute, positive effects on mood and can lead to antidepressant effects over time when repeated regularly. The mechanisms underlying the antidepressant effects of exercise training are not well known, limiting the prescription of exercise training for depression. Serum Insulin-Like Growth Factor-1 (IGF-1) appears dysregulated in those with Major Depressive Disorder (MDD), suggesting MDD could inhibit or alter the IGF-1 response to exercise.

Effect of acute and long-term exercise on leptin levels in depressed outpatients.

Background: Depression is a leading cause of disability worldwide and a significant contributor to the global burden of disease. Altered leptin levels are known to be associated with depressive symptoms, however discrepancies in the results of increased or decreased levels exist. Due to various limitations associated with commonly used antidepressant drugs, alternatives such as exercise therapy are gaining more importance.

Physical fitness is associated with neural activity during working memory performance in major depressive disorder.

Background: Deficits in cognition like working memory (WM) are highly prevalent symptoms related to major depressive disorder (MDD). Neuroimaging studies have described frontoparietal abnormalities in patients with MDD as a basis for these deficits. Based on research in healthy adults, it is hypothesized that increased physical fitness might be a protective factor for these deficits in MDD.

Validating the German Short Basic Psychological Need Satisfaction and Frustration Scale in Individuals with Depression.

Satisfaction and frustration of the needs for autonomy, competence, and relatedness, as assessed with the 24-item Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS), have been found to be crucial indicators of individuals' psychological health. To increase the usability of this scale within a clinical and health services research context, we aimed to validate a German short version (12 items) of this scale in individuals with depression including the examination of the relations from need frustration and need satisfaction to ill-being and quality of life (QOL). This cross-sectional study involved 344 adults diagnosed with depression (M (SD) = 47.
