Walking, jogging, yoga and strength training found to ease depression

Walking or jogging, yoga and strength training seems to be the most effective exercises to ease depression, either alone or alongside established treatments such as psychotherapy and drugs, suggests an evidence review published by The BMJ.

Even low-intensity activities such as walking or yoga are beneficial, but the results suggest that the more vigorous the activity, the greater the benefits are likely to be.

The authors stress that confidence in many of the findings remains low and more high-quality studies are needed, but they say these forms of exercise "could be considered alongside psychotherapy and drugs as core treatments for depression."

The World Health Organization estimates that more than 300 million people worldwide have depression. Exercise is often recommended alongside psychotherapy and drugs, but guidelines and previous evidence reviews disagree on how to prescribe exercise to treat depression best.

To address this uncertainty, researchers trawled databases looking for randomized trials that compared exercise as a treatment for depression with established treatments (e.g., SSRI antidepressants, ), active controls (e.g., usual care, placebo tablet), or untreated controls.

They found 218 relevant trials involving 14,170 participants with depression for analysis. Each trial was assessed for bias, and the type, intensity, and frequency of each exercise intervention were recorded.

Other potentially influential factors such as participants' sex, age, baseline levels of depression, existing conditions, and differences between groups were also taken into account.

Compared with active controls, large reductions in depression were found for dance and moderate reductions for walking or jogging, yoga, strength training, mixed aerobic exercises, and tai chi or qigong.

Moderate, clinically meaningful effects were also found when exercise was combined with SSRIs or was combined with psychotherapy, suggesting that exercise could provide added benefit alongside these established treatments.

Although walking or jogging were effective for both men and women, strength training was more effective for women, and yoga or qigong was more effective for men. Yoga was also more effective among , while was more effective among younger people.

While light physical activity such as walking and yoga still provided clinically meaningful effects, the benefits were greater for vigorous exercise such as running and interval training.

Exercise appeared equally effective for people with and without other and with different baseline levels of depression. Effects were also similar for individual and group exercise.

The authors acknowledge that the quality of evidence is low, and very few trials monitored participants for one year or more. Many patients may also have physical, psychological, or to participation, they note.

Nevertheless, they suggest a combination of social interaction, mindfulness, and immersion in that may help explain the positive effects.

"Our findings support the inclusion of exercise as part of clinical practice guidelines for depression, particularly vigorous-intensity exercise," they say. "Health systems may want to provide these treatments as alternatives or adjuvants to other established interventions while also attenuating risks to physical health associated with depression."

"Primary care clinicians can now recommend exercise, psychotherapy, or antidepressants as standalone alternatives for adults with mild or moderate depression," explains Juan Ángel Bellón at the University of Malaga in a linked editorial.

He points out that taking regular exercise can be challenging for people with depression and says studies using real world data are needed to evaluate physical activity programs for people with .

He notes that the European Union has recently committed to promoting exercise across member states and urges health services and local and national administrations to "provide enough resources to make individualized and supervised exercise programs accessible to the entire population."
