Research conducted at the University of Colorado, Boulder, implies that humans who are forced to exercise, including those who feel like they have to exercise for health reasons, may still get benefits in terms of reducing anxiety and depression. The study was based on a lab experiment using rats. During a six-week period, some rats remained sedentary, while others exercised by running on a wheel, either forced or when they chose to. All were then exposed to stressful situations. Regardless of whether the rats chose to run or were forced to run, they were protected against stress and anxiety reactions when compared to the sedentary rats.
