Assessing Clinical and Cognitive Outcomes in Depressed Youth Following Chronic Cardiovascular Exercise
Bibliographic record
Abstract
Cardiovascular exercise is an empirically supported treatment for major depressive disorder (MDD); however, its effect on cognitive functioning is understudied. We examined how cardiovascular exercise influenced cognitive functioning in healthy youth and youth with MDD aged 16-24 (N = 51). We also assessed how twelve weeks of aerobic exercise intervention influenced cognitive functioning and depressive symptoms in youth with MDD. The Beck Depression Inventory (BDI) was used to measure depressive symptoms and the NIH Cognition Toolbox was used to calculate fluid and crystallized cognition composite scores. We expected increased cognitive functioning to correlate with larger decreases in MDD symptoms. We found no significant differences in baseline cognition scores between healthy and depressed youth. There were no significant differences between changes in VO2 max (an index of cardiovascular fitness) and depressive symptoms or cognition scores in depressed youth. We found a trend for an improvement in cognition scores after exercise intervention, suggesting that consistent cardiovascular exercise could enhance cognition. This study advances our understanding of aerobic exercise as a treatment modality for youth with MDD and the importance of alternative therapeutic interventions in depression.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
