Study Notes
Energy Expenditure and METs
- One MET (Metabolic Equivalent of Task) represents the energy cost of sitting quietly, equivalent to an oxygen uptake of 3.5 ml/kg/min.
- A MET of 2 represents an energy expenditure that is twice the resting energy expenditure, equivalent to an oxygen uptake of 7 ml/kg/min.
Exercise and Physical Activity
- Exercise is a type of physical activity that is planned, structured, and repetitive, with the goal of improving or maintaining physical fitness.
- Physical activity is a broader term that includes all bodily movements, regardless of their purpose or intensity.
Types of Physical Activity
- The primary factor that distinguishes varying types of physical activity is its intensity, which is often measured in METs.
Physical Fitness
- The main purpose of physical fitness is to improve overall health and well-being by developing the ability to perform daily tasks with vigor and efficiency.
