PEBPE Standards
• PEBPE2.d: The learner will be able to integrate health and skill related fitness components into their daily activities.
• PEBPE3.a: The learner will participate in fitness assessments and developmentally appropriate health-related fitness activities.
• PEBPE3.c:The learner will participate regularly in all fitness activities while dressing safely/appropriately, and actively engage in all practice and exercise settings.
• PEBPE6.a:The learner will describe the role physical activity plays, in reducing the risk factor for disease, by maintaining appropriate health-related fitness components.

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
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
Lesson 1:Your Heart, Lungs, and Circulation
• 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
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
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
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
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
Lesson 3:Influences on Cardiac-respiratory
Endurance
Factors Affecting Cardiorespiratory Endurance:
• Age
• Heredity
• Gender
• Body Composition
• Level of Conditioning
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
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
