Exercise as medicine for depressive symptoms? A systematic review and meta-analysis with meta-regression
Published 2023Reviewer Insight4/21/2026- Exercise vs. antidepressants — not directly compared: This study only compares exercise to no treatment or waitlist controls, not to antidepressant medication. Claiming exercise is as effective as antidepressants based on this paper goes beyond what the evidence shows.
- Indirect comparison is flawed: The study attempts to compare exercise and antidepressant effectiveness using figures from two completely different research studies with different methods — this is like comparing apples to oranges.
- Medication-naive participants only: Studies where participants were already taking antidepressants were excluded, meaning we cannot draw conclusions about how exercise compares to medication for people who might need it.
- What this paper actually supports: Exercise significantly reduces depressive symptoms compared to no treatment, particularly when supervised, higher intensity, and practiced consistently. This makes exercise a well-supported complementary or standalone intervention for depression — but not yet proven equivalent to antidepressants.
- Bottom line: Exercise likely helps with depression, but this study cannot tell us whether it works as well as antidepressants — that question remains unanswered by this research.
