Exercise Rivals Therapy in Fighting Depression

Exercise as an Alternative to Psychological Therapy

An increasing number of studies suggest that physical activity can reduce symptoms of depression nearly as effectively as psychological therapy, without requiring a medical prescription. A comprehensive review of recent studies indicates that exercise can alleviate depression compared to psychotherapy, offering benefits similar to those of antidepressant medications, although the evidence in this regard is less conclusive. Moderate-intensity physical activity, conducted over multiple sessions, has proven to be the most effective, with few side effects. While it is not a universal solution, exercise can be a powerful and accessible tool for many individuals.

The Impact of Exercise on Mental Health

According to research conducted by scientists at the University of Lancashire, physical exercise led to a moderate reduction in depressive symptoms compared to the absence of treatment. Compared to psychological therapy, exercise provided similar improvements, based on moderate evidence from ten studies, while comparison with antidepressant medications suggested comparable effects, although evidence was limited. Reported side effects were rare, and most participants in exercise programs only experienced minor muscle or joint injuries, while those taking antidepressants reported typical medication-related issues, such as fatigue and gastrointestinal problems.

Which Types of Exercises Are Most Effective?

The review found that light to moderate-intensity activities may be more beneficial than intense workouts. The greatest improvements in depressive symptoms were associated with completing between 13 and 36 exercise sessions. There was no single type of exercise that clearly outperformed others; however, programs combining different types of activity and resistance training proved to be more effective than aerobic exercise. Activities such as yoga, qigong, and stretching were not evaluated in this analysis and remain an area for future research.

Conclusions and Recommendations

While the review added 35 new studies to previous versions from 2008 and 2013, the main conclusions did not significantly change. Many of the included studies were small, often involving fewer than 100 participants. Thus, larger and higher-quality studies are needed to determine the most effective types of exercises, whom they benefit, and whether these benefits are sustained over time.
