Which of the following describes physical activity?

Physical activity is best defined as any movement produced by skeletal muscle that results in energy expenditure. This broad definition encompasses a wide variety of activities, including everyday actions like walking, gardening, and playing with children, alongside more structured forms of exercise. The key aspect of this definition is the emphasis on movement and energy use, which highlights the importance of incorporating physical activity into daily life for overall health and well-being.

While structured team sports and planned exercise routines are forms of physical activity, they represent only a subset of all possible movements that qualify as physical activity. Meditation sessions and theoretical exercises do not involve physical movement of the skeletal muscles and therefore do not meet the criteria for physical activity as defined in this context.
