• What evidence is there to support the assertion that exercise can be useful in the treatment of depression?
• What is known from the cross-sectional and prospective studies regarding the association between (lack of) activity and depression?

If one was to prescribe exercise to an individual suffering from depression, what would the prescription entail (i.e., type, frequency, intensity, duration)?

• Several recent studies examining the effects of exercise on depression have shown that exercise does not alleviate depressive symptoms better than pharmacological (i.e., drug) treatments. As an exercise scientist, how would you use this evidence to convince others that exercise is worth the effort for the depressed individual?
