2.  Look at your Activity Log Handout (homework) › How many of you were physically active?  What are some of the things you did? (Make list on board)  How many hours did you spend sleeping, watching TV or a movie, working, or playing on your computer or phone?  Did any of these activities make you breath harder?  Did your muscles work?  Did you stretch before hand?

3.  Physical Fitness – The ability of the body to function at its best.  Helps a person meet the demands of daily life and have energy  Less tired and handle stress better *** Discussion: Look back at the definitions you wrote down during bell ringer. How do they compare?

4.  Cardiorespiratory (Aerobic) Fitness › How well the heart and lungs supply oxygen to the body so the muscles can work.  Cardio – heart, Respiratory – lungs  Examples of these activities are: › Power walking, swimming, dancing…  Help prevent heart disease, stroke, and diabetes.  Lower blood pressure and cholesterol.  Lose or maintain weight and reduce stress.

5.  Muscular Strength › 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: › Sprinting, climbing, push-ups….

6.  Muscular Endurance › How well the muscle can keep performing work or doing an activity.  The key is to doing an activity long enough to get the physical benefits.  Examples of these activities are: Running, rolling a wheelchair, swimming…

7.  Flexibility › Ability of joints to move through a full range of motion  Makes it less likely that muscles will be injured during physical activity.  Increases blood flow and improves posture by preventing muscles from getting tight.  Relieve stress  Examples of these activities are: › Dance, yoga, stretching, martial arts…

8.  Frequency- how often you do the activity  Intensity- how hard your body works  Time – how long you do the activity each time.

9.  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 15 or 6 seconds › For 6 seconds – add 0 to the number  Target Heart Rate › 120-160 bpm  Max Heart Rate › 220-age

10.  Find Pulse  Jog in Place for 1 minute  How many of you were at your target heart rate after jogging in place for a minute?  How many of you do physical activity that puts your heart within this target heart rate range at least 3 times a week?  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.

11.  Squeeze fist as tight as you can › Slowly curl fist toward your shoulder, bending your elbow. Feel muscles and contractions.  Muscular strength is increased through activities that require the muscles to do more and more work over time ( overload ).  Aerobic (cardiorespiratory) activities – use O2 to burn carbs and fats  Anaerobic (strength) activities- build muscle and burn carbs without O2. Short periods of time.

12.  What are some activities that would build muscular strength?  Now make the same fist and complete the exercise 10 times quickly. How does it feel now?

13.  Endurance is often the key to success in sports.  Training builds endurance by increasing the capillaries or small blood vessels in the muscles so they can receive more blood and oxygen during exercise. › More O2 = work longer  Slowing increasing FIT improves muscular endurance.

14.  Stand up and try to touch your toes… › Feel your muscles and joints as you do this  Flexibility depends on how elastic the muscles and connective tissues (tendons and ligaments) are  More flexible - the less likely to be injured  Help to maintain the range of motion when people train for strength and endurance.

15.  Explore benefits of physical activity (TE pg.79-81)  Teacher – label three columns on the board physical, mental/emotional, and social.  How does being physically active help keep your body healthy?  What physical health advantages would someone who does regular physical activity have over someone who was inactive?

16.  Teens who participate in regular physical activity: › Have a stronger heart and lungs (better cardiorespiratory fitness) › Have stronger muscles and more endurance › Are more flexible and less likely to be injured during activity › Have less body fat and more likely to be a healthy weight › Have more energy › Sleep better › Have a better chance of a healthy adult life

17.  Teens want to look good and feel good  Regular physical activity helps you have more energy and handle stress better  Reduces mood swings and depression  Physical activity can help your grades by improving your memory and concentration  Increase confidence and feel good about yourself  Build friendships and meet social needs through team activities  Fun way to connect and share with family/friends

18.  Log into socrative.com › Room: DHJHEALTH  Suppose a friend asked you, “What’s so bad about being inactive?” › Explain how an inactive lifestyle contributes to chronic disease and give a specific example.
