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.
