Classification of physical activity (ISTAC: CL_SURVEYS_PHYSICAL ACTIVITY)

Physical activity is defined as any body movement produced by skeletal muscles that results in a caloric expenditure for which it must have certain characteristics of intensity, duration and frequency. This classification identifies the physical activity that the person most frequently performs in his daily activity of work, studies, housework or in his free time, and / or the periodicity with which the person performs some physical activity. Physical activity levels are also collected according to the IPAQ (International Physical Activity Questionnaire) instrument that allows us to classify people according to low, moderate and high activity levels.
