Chapter 7 (Unit 1) Cardiorespiratory Endurance Name: _____________________________ Date: ______________ Period _____ Define Cardiorespiratory Endurance: The ability of the body to work continuously for extended periods of time What are the benefits of Cardiorespiratory? __Increased energy_______________________________________________ __Less stress in their lives_________________________________________ __Look and feel better____________________________________________ Aerobic vs. Anaerobic Aerobic – continuous activity that requires large amounts of oxygen Aerobic means “with oxygen” Aerobic strengthens the heart, organs, and lungs Type of aerobic exercises: rowing, running, swimming, cross-country skiing, etc. Define Maximal Oxygen Consumption (VO2max): the largest amount of oxygen your body is able to process during strenuous aerobic exercise. Anaerobic – activity that requires high levels of energy and is done for only a few seconds or minutes at a high level of intensity. Anaerobic means “without oxygen” Anaerobic strengthens higher levels of muscular strength, muscular endurance, and flexibility. Type of anaerobic exercises: sprinting, fast break, and stretching. The Circulatory and Respiratory System consist of: Consist of the heart, lungs, blood and blood vessels. Lists the Parts for the following: The Heart Hemoglobin – an iron rich compound in the blood that helps carry the oxygen Stroke Volume – the amount of blood pumped per beat of the heart The heart beats an average of __72________ times per minute. The Blood Vessels Arteries – vessels that carry blood (oxygenated )from the heart to the major extremities – such as the arms, legs and head Capillaries – delivers oxygen and other nutrients to individual cells Veins – deliver the blood back to the heart (deoxygenated blood) Name three functions of the Respiratory System: 1. _The body system that exchanges gases between your body and the environment.__ 2. __The principal organ = LUNGS_ 3. _The lungs exchange oxygen and carbon dioxide, this is called respiration.__ Label the Heart Diagram - You will need a red and a blue marker to complete the Heart Diagram - Trace the pathway of the circulatory system in the Heart See Heart Diagram for this section List the problems of your Heart & Lungs: Lifestyle Diseases – disease that are result of certain lifestyle choices. List the choices: _Inactivity (sedentary) __ _Being overweight______ _Smoking and using other forms of tobacco___ _Eating foods high in fat & cholesterol___ Cardiovascular disease (CVD) – medical disorder that affects the heart or blood vessels Atherosclerosis – a condition in which a fatty deposit called “Plaque” builds up inside arteries, restricting or cutting off blood flow List the major concerns: _Heart Attacks__ _Sudden Cardiac Death__ _Stokes – brain is cut off of oxygen__ _Peripheral Vascular Disease__ _Hypertension - which means High Blood Pressure__ _Emphysema – disease of the lungs__ List three ways to care for your Heart and Lungs: 1. _Take care of the Circulatory & Respiratory System__ 2. _Change your lifestyle behaviors__ 3. _Have your blood pressure checked__ Define Blood Pressure – The force of the blood in the main arteries Normal blood pressure “120/80” Systolic Pressure – top number measures the greatest pressure point Diastolic Pressure – bottom number measures lowest point, heart relaxes Make the Most of What You Have _Start while you are young__ _Stay active__ _Pay attention to fitness factors you can control _ _Make your body work for you, rather than against you__
