Document Summary
Fitness: the ability to perform routine physical activity without undue fatigue. Overload principle: adaptation to stress during exercise (the more you do, the more you are capable of doing) Determines how long you can continue a task: increases stroke volume, increases aerobic capacity or vo2 max: maximum amount of oxygen that can be consumed with tissue during exercise. Increased by aerobic exercise: increased heart rate, increased use of oxygen. Regular aerobic exercise: decreases resting heart rate. Increased by repeatedly using muscles to move against a resting force resistance or strength training. Also improve bone density prevents osteoporosis. Range of motion: stretching of ligaments and muscles, improves with regular movement. Fitness higher proportion of lean body mass. Regular exercise increases muscle mass increases resting energy metabolism (ree) Cardiovascular health: lower blood pressure, increase in blood levels of hdl cholesterol ( good" cholesterol) Diabetes prevention and management: exercise increases insulin sensitivity.
