4. Essential Question
What are ways that I can improve my cardiorespiratory endurance on a daily basis?

5. Lesson 1: Your Heart, Lungs, and Circulation
Aerobic activity: continuous activity that requires large amounts of oxygen( aerobic means “with oxygen.”)
Examples: rowing, step aerobics because these activities strengthen the heart

6. Lesson 1: Your Heart, Lungs, and Circulation
Circulatory System: consists of the heart, blood, and blood vessels
Heart: main organ of the circulatory system
Right side of heart pumps blood to the lungs and the left side pumps oxygen-rich blood to rest of body
Hemoglobin: iron rich compound in the blood that helps carry the oxygen throughout the body
Stroke Volume: amount of blood pumped per beat of the heart.

7. Lesson 1: Your Heart, Lungs, and Circulation
Circulatory System:
Blood Vessels: blood is carried to and from the heart
Arteries: vessels that carry blood from the heart to the major extremities (arms, legs, and heart)
Capillaries: smaller blood vessels, deliver oxygen and other nutrients to individual cells
Veins: deliver the blood back to the heart

8. Lesson 1: Your Heart, Lungs, and Circulation
Respiratory System: body system that exchanges gases between your body and the environment
Diaphragm: muscle found between the chest cavity and abdomen; when you inhale, the diaphragm contracts and moves downward (chest cavity enlarges, allowing air into the lungs) and when you exhale, the opposite motion occurs

9. Lesson 1: Your Heart, Lungs, and Circulation
Cardiorespiratory Endurance: ability of the body to work continuously for extended periods of time

10. Lesson 2: Problems and Care of Your Heart and Lungs
Lifestyle Diseases: diseases that are the result of certain lifestyle choices
Examples: drinking alcohol, smoking, poor eating habits, sedentary

11. Lesson 2: Problems and Care of Your Heart and Lungs
Cardiovascular Disease (CVD): medical disorder that affects the heart or blood vessels
CVD is the leading cause of death in the United States; taking 950,000 lives a year
Atherosclerosis: condition in which a fatty deposit called plaque builds up inside arteries, restricting or cutting off blood flow

12. Lesson 2: Problems and Care of Your Heart and Lungs
Stroke: blood flow to a person’s brain is interrupted or cut off entirely by the blockage of an artery
Peripheral Vascular Disease: a CVD that occurs mainly in the legs, and less frequently in the arms
Hypertension: risk factor in heart attack, stroke, and heart failure
Emphysema: disease in which the small airways of the lungs lose their normal elasticity, making them less efficient in helping to move air in and out of the lungs

13. Lesson 2: Problems and Care of Your Heart and Lungs
Changeable Risk Factors:
Avoiding tobacco
Maintaining a healthy weight
Eating right
Having regular medical checkups

14. Lesson 3: Influences on Cardiac-respiratory Endurance
Maximal Oxygen Consumption (VO2 Max): largest amount of oxygen your body is able to process during strenuous aerobic exercise
VO2 Max: measures the amount of oxygen in millimeters per kilogram of body weight per minute

15. Lesson 3: Influences on Cardiac-respiratory Endurance
Factors Affecting Cardiorespiratory Endurance:
Age
Heredity
Gender
Body Composition
Level of Conditioning

16. Lesson 3: Influences on Cardiac-respiratory Endurance
Slow-twitch muscle fibers: muscle fibers that contract at a slow rate, allowing for greater muscle endurance
Fast-twitch muscle fiber: muscle fibers that contract rapidly, allowing for greater muscle strength

17. Lesson 4: Aerobic vs. Anaerobic Physical Activities
Anaerobic Activity: activity that requires high levels of energy and is done for only a few seconds or minutes at a high level of intensity
Anaerobic Fitness: higher levels of muscular strength, muscular endurance, and flexibility
Interval Training: programs in which high-intensity physical activities alternate with low-intensity recovery bouts for several minutes at a time
