Study Notes
Definition of Physical Activity
- The most widely accepted definition of physical activity was published by Caspersen et al. in 1985.
- According to this definition, physical activity is "any bodily movement produced by skeletal muscles that results in energy expenditure".
- This definition frames physical activity as a specific mechanistic act, focusing on the role of skeletal muscles and energy expenditure.
Characteristics of the Definition
- The focus on skeletal muscles emphasizes the physical aspect of the activity.
- The emphasis on energy expenditure highlights the physiological impact of physical activity.
