According to a new study conducted by Simon Bacon, Ph.D., people with depression may take longer to recover after strenuous exercise. The study looked at the stress test results of 900 patients who may have heart disease or who have a family history of heart disease. Before entering the study, participants were given a psychiatric evaluation. The study found that those with depression took longer to relax after strenuous exercise. Dr. Bacon is an assistant professor of exercise science at Concordia University, Montreal.
