Previous meta‐analyses investigating the effect of exercise on depression have included trials where the control condition has been categorized as placebo despite the fact that this particular placebo intervention (e.g., meditation, relaxation) has been recognized as having an antidepressant effect.

Exercise for depression in older adults: a meta-analysis of randomized controlled trials adjusting for publication bias.
TLDR
adjusting for publication bias increased the beneficial effects of exercise in three subgroup analysis, suggesting that previous meta-analyses have underestimated the benefits of exercise due to publication bias.
Challenges Establishing the Efficacy of Exercise as an Antidepressant Treatment: A Systematic Review and Meta-Analysis of Control Group Responses in Exercise Randomised Controlled Trials
TLDR
A systematic review and meta-analysis investigating CGRs and predictors in control groups of exercise RCTs among adults with depression found a large CGR of improved depressive symptoms was evident across all studies.
Exercise for depression in older adults: a meta-analysis of randomized controlled trials adjusting for publication bias
TLDR
It is advocated that exercise be considered as a routine component of the management of depression in older adults, suggesting that previous meta-analyses have underestimated the benefits of exercise due to publication bias.
Systematic review and meta-analysis of the effects of exercise on depression in adolescents
TLDR
Physical exercise has a positive effect on the improvement of depression in adolescents and is a better choice for adolescents with depression and depressive symptoms.
Quantifying the Placebo Effect in Psychological Outcomes of Exercise Training: A Meta-Analysis of Randomized Trials
TLDR
A small body of research suggests both that (1) the placebo effect is approximately half of the observed psychological benefits of exercise training and (2) there is an urgent need for creative research specifically aimed at better understanding the role of the Placebo effect in the mental health consequences of exerciseTraining.
Moderating Effects of Exercise Duration and Intensity in Neuromuscular vs. Endurance Exercise Interventions for the Treatment of Depression: A Meta-Analytical Review
TLDR
Interestingly, exercise duration in endurance trials and exercise intensity in neuromuscular trials had a significantly moderating effect on exercise in depression, which might be used on Exercise in depression to increase efficacy.
Exercise as a treatment for clinical depression in adults and progressing the physiotherapists role: A systematic review and meta-analysis
TLDR
The results of the meta-analysis reveal that exercise as a sole treatment and as an add-on is significantly effective in reducing depressive symptoms, and support the use of moderate intensity aerobic exercise for three sessions per week.

TLDR
Examination of the antidepressant influence of an 8-week-long aerobic exercise intervention in which two training parameters were manipulated showed lower depression scores than those in the low-frequency (control) group at 4 weeks and 8 weeks, but alleviation in depressive symptoms was not found to be greater in those participants who received a group-based intervention.
