5. Components of Fitness
Summarize under “Cardiorespiratory Fitness” pg 57
How well the heart and lungs supply oxygen to the body so the muscles can work.
Cardio – heart
Respiratory – lungs
Also called aerobic fitness or aerobic capacity
Examples of these activities are?
Power walking, swimming, dancing…

6. Components of Fitness Summarize under “Muscular Strength” pg 57
Amount of force muscles can exert when they contract.
Helps move the body more efficiently
Support and protect joints and internal organs
Examples of these activities are?
Weight lifting, climbing, push-ups….

7. Components of Fitness Summarize under “Muscular Endurance” pg 57
How well the muscle can keep performing work or doing an activity.
The key to doing an activity long enough to get the physical benefits
Examples of these activities are?

8. Components of Fitness Summarize under “Flexibility” pg 58

Makes it less likely that muscles will be injured during physical activity.
Increases blood flow
Improves posture by preventing muscles from getting tight.
Relieve stress
Examples of these activities are?
Dance, yoga, stretching, martial arts…

9. Cardiorespiratory Fitness
Built by doing physical activities that challenge the heart and lungs.
Aerobic activities
Breathe harder and heart beats faster
Move your large muscle groups (arms and legs)
Help prevent heart disease, stroke, and diabetes.
Lower blood pressure and cholesterol
Lose or maintain weight and reduce stress

10. Building Aerobic Fitness: F.I.T.
Frequency- how often you do the activity
Intensity- how hard your body works (Heart rate)
Time – duration; how long you do the activity each time

11. Find your heart rate following the steps below: pg 58
Feel for your pulse under the angle of the jaw using your index and middle finger. Do not use your thumb. Use very light pressure.
Count your pulse for 6 seconds
For 6 seconds – multiply by 10 (rate per minute)
Then find your Target Heart Rate: Formula (60%-80% of max Heart rate)
220 – (your age) x .6 = low end of range
220 – (your age) x .8 = high end of range

12. Cardiorespiratory Fitness Continue.
Frequency and Intensity contribute to aerobic fitness
To gain health benefits:
Aerobic activities at least 3 times a week for at least 30 minutes each time.
