World Health Organization 2020 guidelines on physical activity and sedentary behaviour

These 2020 WHO guidelines update previous WHO recommendations released in 2010. They reaffirm messages that some physical activity is better than none, that more physical activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours. These guidelines highlight the importance of regularly undertaking both aerobic and muscle strengthening activities and for the first time, there are specific recommendations for specific populations including for pregnant and postpartum women and people living with chronic conditions or disability. These guidelines should be used to inform national health policies aligned with the <i>WHO Global Action Plan on Physical Activity 2018-2030</i> and to strengthen surveillance systems that track progress towards national and global targets.
