Cardiorespiratory Ftness fall 2011

  1. 1. VALERIE BURGE-HALL TNCC HEALTH 116 Photo By: Mykl Roventine Creative Commons Attribution Cardiorespiratory Fitness
  2. 2. Cardio Respiratory System: The Basics <ul><li>The system that circulates blood throughout </li></ul><ul><li>the body; consists of: </li></ul><ul><li>Heart: pumps deoxygenated blood into the lungs (right/pulmonary) and delivers oxygen rich blood to the rest of the body (left/systemic) </li></ul><ul><li>Blood Vessels: veins carry blood to the hears; arteries carry blood away from the heart; capillaries (tiny veins) deliver oxygen rich blood to the tissues. </li></ul><ul><li>Lungs (respiratory system): supplies oxygen to the body and removes carbon dioxide </li></ul>
  3. 3. Activity Function and Energy Production <ul><li>Function of the cardiorespiratory system: </li></ul><ul><li>At rest: heart beats 50-90 beats per minute; 12-20 breaths per minute </li></ul><ul><li>During exercise: heart rate increases to 170-210 beats per minute; increase stroke volume and cardiac output of heart; blood flows to muscles; 40-60 breathes per minute </li></ul>
  4. 4. Blood Pressure <ul><li>A measure of the force exerted against the walls of </li></ul><ul><li>the vessels by the blood flowing through them. </li></ul><ul><li>Systolic Blood </li></ul><ul><li>Pressure </li></ul><ul><li>Highest blood pressure when the heart contracts. </li></ul><ul><li>Diastolic Blood </li></ul><ul><li>Pressure </li></ul><ul><li>Lowest blood pressure between contractions of the heart. </li></ul><ul><li>What is considered normal for most Americans? </li></ul>
  5. 5. <ul><li>Improved functioning </li></ul><ul><li>Improved metabolism </li></ul><ul><li>Reduced Risk of Chronic Disease </li></ul><ul><li>Control of Body Fat </li></ul><ul><li>Improved Immune Functioning </li></ul><ul><li>Improved Emotional Well-being </li></ul>Benefits of Cardiorespiratory Exercise
  6. 6. Assessing Cardiorespiratory Fitness <ul><li>These are simple tests that can be used to test your maximal oxygen consumption during activity: </li></ul><ul><li>1-mile walk test: based on amount of time it takes to complete a brisk 1-mile walk and your heart rate at the end; fast time and low heart rate indicate a high level of cardiorespiratory endurance </li></ul><ul><li>3 minute step test: based on the rate at which your pulse returns to normal after intense activity; the faster it returns to normal, the higher your cardiorespiratory endurance </li></ul><ul><li>1.5 mile run-walk test: based on amount of time it takes to complete; the faster the speed, the better your oxygen consumption </li></ul>
  7. 7. Get Up and Get Moving <ul><li>Homework: </li></ul><ul><li>Choose one of the techniques for assessing cardiorespitory fitness? </li></ul><ul><li>Use pages 80 to 82 in your book to get directions and to record your results. </li></ul>
