In patients with mood disorders, what is a key consideration when prescribing exercise?

• A. Exercise should be avoided due to risk of mood worsening.
• B. Aerobic and resistance exercise can improve depressive symptoms; monitor adherence.
• C. Only flexibility training is beneficial.
• D. Exercise has no impact on mood.

Answer: (B)

Regular physical activity can help mood disorders, and the important point is that both aerobic and resistance training can reduce depressive symptoms, with the real benefit tied to staying adherent to the program. Exercise brings mood improvements through several pathways—better sleep, increased energy, and changes in brain signaling like higher BDNF—so consistent participation drives meaningful change. When prescribing, tailor the plan to the person’s preferences and fitness level, start gradually, and use a sustainable progression. Actively monitor adherence and mood symptoms over time, adjusting frequency, intensity, and type as needed to keep the person engaged and safe. This approach reflects the evidence that exercise helps mood and that sticking with it matters, rather than suggesting exercise is harmful, limited to only flexibility training, or has no mood impact.
