Essential Question

• What are ways that I can improve my cardiorespiratory endurance on a daily basis?

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

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.

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


• 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


• Cardiorespiratory Endurance: ability of the body to work continuously for extended periods of time

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


• 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


• 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


Changeable Risk Factors:

• Avoiding tobacco

• Maintaining a healthy weight

• Eating right

• Having regular medical checkups

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


Endurance

Factors Affecting Cardiorespiratory Endurance:

• Age

• Heredity

• Gender

• Body Composition

• Level of Conditioning


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

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
