**4. Physical activity guidelines for mental health conditions**

The most recent physical activity guidelines from World Health Organization, in 2020, highlight the positive effects of physical activity on mental health, specifically reducing symptoms of anxiety and depression [33]. These recommendation covers subgroups, such as children and adolescents, adults, older adults, pregnant and postpartum women, adults and older adults with chronic conditions, children and adolescent, and adults living with disability, but did not include a specific recommendation to common mental illness, such as anxiety and depression.

The global recommendations suggest that adults should participate in at least 150–300 min of moderate-intensity aerobic physical activity or at least 75–150 min of vigorous-intensity aerobic physical activity per week and for additional health benefits on at least 2 days a week of muscle-strengthening activities at the moderate or greater intensity that involver all major muscle groups [33].
