Physical Activity

1. Physical Activity

2. Physical Activity- • Any form of movement that causes your body to use energy A.) Physical Fitness- ability to carry out task easily and have enough left to respond to an unexpected demand

3. Physical Benefits • Cardiovascular System • Respiratory System • Nervous System

4. Risk of Being Physical Inactive • A.) Type 2 diabetes • B.) Osteoporosis- when the bones become porous and fragile

5. Weight Control • A.) Metabolism- process by which your body gets energy from food

6. Elements of Fitness • A.) Cardio respiratory- ability of the heart, lungs, and blood vessels to send fuel and oxygen to the body • B.) Muscular Strength- amount of force a muscle can exert • C.) Muscular Endurance- ability of the muscle to perform a physical task over a period of time without being fatigued

7. Cont. • D.) Flexibility- ability to move a body part through a full range of motion • E.) Body Composition- ratio of body fat to lean body tissue • F.) Exercise- a planned physical activity

8. Improving Fitness • A.) Aerobic Exercise- activity that uses large muscle groups • B.) Anaerobic Exercise- intense short burst of activity • C.) Isometric Exercise- activity that uses muscle tension to improve muscular strength with little or no movement(push against a wall)

9. Cont. • D.) Isotonic Exercise- activity that combines muscle contraction and repeated movement( push ups and pull ups) • E.) Isokinetic Exercise- activity in which a resistance is moved through an entire range of motion (using a stationary bike, treadmill)

10. Basic of Physical Activity • A.) Overload- working the body harder than normal • B.) Progression- the gradual increase to overload • C.) Workout- the part of an exercise program when the activity is performed

11. F.I.T.T • A.) Warm up- preparing the muscles for work • B.) Frequency- how often you do the workout • C.) Intensity- how hard you work • D.) Time- how much time you devote • E.) Type- which activity you select • F.) Cool Down- activity that prepares the muscles to return to a resting state

12. Weather Related Risk • A.) Hot Weather 1.) Overexertion- over working the body 2.) Heat Cramp- muscle spasms that result from loss of salt and water through sweat 3.) Heat Stroke- when the body loses its ability to rid itself of heat through sweat B.) Cold Weather 1.) Frostbite- condition that results when body tissue becomes frozen

13. Cont. 2.) Hypothermia- when body temperature becomes dangerously low

14. Minor Injuries • Muscle Cramp- spasms or sudden tightening of the muscle • Strain- condition resulting from damaging a muscle or tendon • Sprain- injury to a ligament surrounding a joint

15. Major Injuries • Fractures- break in the bone • Dislocations- when a bone is forced out of the joint • Tendonitis- when tendons and fibers are stretched or torn. • Concussions- a blow to the head that causes swelling to the brain.

16. Target heart rate • Heart rate that you reach when working out A.) Resting heart rate- the number of time your heart beats when you are not active.
