Document Summary
The three primary levels of physical activity. Physical fitness - highest level we want to achieve. Physical activity and exercise are necessary. Form of physical activity that is organized and structured. Standard metabolic equation that gives estimate of energy or oxygen that our body uses to be physically active. Often measured in met levels (metabolic equivalents) 1 met = 3. 5 ml o2 per kilogram of bodyweight per minute. If 2 met double 3. 5. The more potential energy = met level will increase. Mets are grouped into three activity categories: (based off met levels) Moderate - - 3- 6 mets. The five health- related components of fitness. Lower risk for chronic disease and optimize health. Deal with efficiency of cardiovascular and respiratory system. Provide oxygen to working muscles during exercise. Ability of muscles to generate and exert force. Ability of muscles to contract repeatedly over time. Ability to move joint through full range of motion.
