Exercising
5 types of exercise:
1- Isometric: involves contracting muscles against an immovable object.
2- Isotonic: contraction of muscles and moving of the joints.
3- Isokinetic: involves exerting effort to move muscles and joints against a variable
amount of resistance.
4- Anaerobic: short intensive bursts of energy but no increased amount of oxygen.
5- Aerobic: any exercise that requires dramatically increasing oxygen consumption
over an extended period of time.
Reasons for Exercising:
Physical Fitness
• Muscle strength and endurance
• Flexibility
• Aerobic fitness
Weight control
Physical health and cardiovascular health:
• Accumulating evidence suggests that physical activity reduces the incidence
of coronary heart disease. Early research has had many flaws and tended to
include only men. More recent research confirms a strong association
between a regime of moderate physical activity and cardiovascular health,
including heart disease and stroke. It can also raise HDL, thereby improving
the ratio of total cholesterol to high-density lipoprotein.
Other Health Benefits of Physical Activity:
Protection against cancer
Prevention of bone density loss
Control of diabetes
Psychological benefits

1- isometric: involves contracting muscles against an immovable object. 2- isotonic: contraction of muscles and moving of the joints. 3- isokinetic: involves exerting effort to move muscles and joints against a variable amount of resistance. 4- anaerobic: short intensive bursts of energy but no increased amount of oxygen. 5- aerobic: any exercise that requires dramatically increasing oxygen consumption over an extended period of time. Physical fitness: muscle strength and endurance, flexibility, aerobic fitness. Physical health and cardiovascular health: accumulating evidence suggests that physical activity reduces the incidence of coronary heart disease. Early research has had many flaws and tended to include only men. More recent research confirms a strong association between a regime of moderate physical activity and cardiovascular health, including heart disease and stroke. It can also raise hdl, thereby improving the ratio of total cholesterol to high-density lipoprotein. Reducing exercise injuries: in the us 67% of adults do not comply to a regular exercise schedule.
