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.
