How does the WHO define physical activity?

The World Health Organization (WHO) defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure. This definition encompasses a wide range of activities, from structured exercise programs and sports to everyday tasks like walking, gardening, or even cleaning. By focusing on the engagement of skeletal muscles and the consequent energy use, the definition recognizes various forms of movement that contribute to overall health, regardless of whether they are part of a formal exercise regimen.

This broad perspective encourages more people to understand that many daily activities can be considered physical activity, making it more accessible and relevant to all individuals. It highlights the importance of incorporating movement into daily life rather than restricting the concept to structured workouts or recreational activities.
