What is physical activity?

WHO defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure -- including activities undertaken while working， playing， carrying out household chores， travelling， and engaging in recreational pursuits.

The term \"physical activity\" should not be confused with \"exercise\"， which is a subcategory of physical activity that is planned， structured， repetitive， and aims to improve or maintain one or more components of physical fitness. Both， moderate and vigorous intensity physical activity brings health benefits.

The intensity of different forms of physical activity varies between people. In order to be beneficial for cardiorespiratory health， all activity should be performed in bouts of at least 10 minutes duration. WHO recommends:

? for children and adolescents: 60 minutes of moderate to vigorous intensity activity per day;

? for adults (18+): 150 minutes of moderate-intensity activity per week.
