Background:

• Major Depressive Disorder (MDD) is a prevalent mental health condition.
• Pharmacotherapy is a common treatment for MDD, but adjunct therapies are needed.
• Exercise interventions show promise in managing depressive symptoms.

Purpose of the Study:

• To evaluate the effectiveness of an affect-adjusted, supervised, multimodal, online, and home-based exercise group protocol as an adjunct therapy to antidepressants.
• To assess the impact of the exercise intervention on depressive symptoms, cardiorespiratory fitness, and antidepressant side effects in adults with MDD.

Main Methods:

• A 12-week randomized controlled trial involving 59 adults diagnosed with MDD.
• Participants were assigned to either an exercise group (EG; exercise + pharmacotherapy) or a control group (CG; pharmacotherapy only).
• The exercise intervention was adjusted based on perceived effort, pleasure, and enjoyment.

Main Results:

• The EG demonstrated a significant increase in cardiorespiratory fitness (CRF), unlike the CG.
• Both groups showed decreased depressive symptoms, but the EG had significantly lower scores at all time points.
• The EG exhibited higher remission rates (42.3% at t1, 72.7% at t2) compared to the CG (27.2% at t1, 48.1% at t2), with sustained effects at follow-up.
• The EG experienced more side effects from antidepressant medication than the CG.

Conclusions:

• Complementing usual care for MDD with this specific exercise protocol leads to superior clinical outcomes.
• The findings support the integration of this affect-adjusted exercise intervention into the clinical management of depression.
• Further research may explore optimizing exercise parameters to mitigate medication side effects.
