  2. 5- Health Related Fitness Areas

  3. Physical Activity Benefits Two Vital Body Systems HEART LUNGS

  4. Cardiovascular (cardiorespiratory Functions • The heart, lungs and blood vessels make up this system (the Cardiorespiratory system) • The heart is the pump and pumps blood around the body. • The lungs oxygenate the blood and remove carbon dioxide • The blood vessels transports oxygenated blood, nutrients and un-oxygenated blood around the body

  5. What does your blood need more of during activity? • Normal resting heart rate is • 55-60 beats per minute • If you don’t get the required amounts of oxygen into your system guess what will happen to your muscles… Breath Fatigue

  6. How hard does your heart have to work? More Active Person • For every heart beat you heart pushes out blood (Stroke Volume) Look at the picture. What conclusion can you come up with between a less active person and a more active person in relation to how hard a heart has to work. Stroke volume Less Active Person

  7. Cholesterol HDL (Happy) Cholesterol • Increased by aerobic exercise, losing weight, not smoking, using canola/avocado/olive oil, cranberry juice, omega-3 (fish), and soluble fibers…eat away the LDL’s (Loser) levels. LDL (LOSER) Cholesterol • These block your arteries and coat them with a plaque like substance that we find on our teeth…YUCK! Atherosclorosis is a disease caused by the build up of plaque in our arteries

  8. Cardiovascular Disease • Atherosclerosis • High Blood Pressure • Heart Attack • Stroke • (Obesity)

  9. Medical Tests for Heart and Lungs • Stress Test • VO2 Max

  10. What is V02 Max and WHY is it being used for our Aerobic Capacity Test?? • A V02 Max test is a test typically administered on a treadmill or cycle in which intensity of exercise is progressively increased. The rate of aerobic metabolism and oxygen uptake increases as intensity of exercise increases up to the point at which the max aerobic capacity is reached.  • Test takes 30 minutes and can only be done with one subject at a time DIFFICULT AND TIME CONSUMING Determine you VO2 max from the calculator below • Mile run = uses age (years), sex (coded 0=F and 1=M), body mass index (BMI inunits of kg×m-2) and Mile Run Time (minutes) for the prediction VO2max = .21 (Age x Sex) - .84 (BMI) - 8.41 (Time) + .34 (Time2) + 108.94 • Pacer = The equation uses the highest speed (km×hr-1) attained on the test, age (y), and the speed x age interaction for the prediction • VO2max =- -3.238 (Max Speed) -3.248 (Age) + 0.1536 (Maximal Speed x Age) + 31.025

  11. What the PFT has given us… • BMI Charts to easily calculate • V02 Max Charts so that we can quickly find out our goals for passing the PFT.

  12. Tests that we use in Physical Education Mile run PACER

  13. Aerobic Activity Anything that lasts • 20-30 CONTINUOUS minutes and raises your heart rate • WITHIN YOUR TARGET HEART RATE RANGE

  14. Active Sport • Any sport that keeps you active (target heart rate range) for 20-30 continuous minutes:

  15. How do you figure your Target Heart Rate for Intensity? • Target Threshold (Bottom #) 220 220 - Age -14 Max Heart Rate 206 X 60% (.60) x60% = Threshold HR 124 You should be working out between these two numbers!!! • Target Ceiling (Top #) 220 220 - Age -14 Max Heart Rate 206 X 90% (.90) x90% = Ceiling HR 185 Target Heart Rate Zone (THRZ) 124-185 - 14 123-184 - 15

  16. Figure My Heart Rate Threshold Ceiling 220 -41 Age 179 x 90% (.9) 161 Ceiling • 220 - 41 Age 179 x 60% (.6) 107 Threshold Target Heart Rate Zone is between 107 - 161

  17. Review What does FITT mean? • Frequency – How often you exercise • Intensity - How hard you work • Time- How long (minutes/hours) will you work out? • Type –What kind of exercise you do?

  18. FITT Formula (what you do)Cardiovascular • F= 3-6 days a week • I= 60% (threshold)-90% (ceiling)THRZ (Target Heart Rate Zone) • T=20-60 continuous minutes • Type= Active (aerobic) Sport

  19. BENEFITS OF A 30-MINUTE WORKOUT GOING ON A WALK, RUN, BIKE, OR SWIM can • Reduce high blood pressure and heart attacks • Builds stronger heart muscle • Clear your arteries of bad cholesterol • Relieve stress • Fight depression • Increase stamina, heart works more efficiently • Help keep off those extra pounds.  • Live longer than people who do not.
