Cardiovascular Fitness

2. Bellwork
What is meant by cardiovascular (or cardiorespiratory) fitness?
List as many sports as you can think of that require some level of cardiovascular endurance.
Be prepared to share your responses with the rest of the class.

3. Objectives 1. Differentiate between aerobic and anaerobic exercise
2. Explain the benefits of cardiovascular fitness
3. Learn how to conduct a cardiovascular assessment

4. Terminology:
Aerobic – exercise that uses oxygen to produce energy and can be performed for an extended period of time
Anaerobic – exercise that does not use oxygen to produce energy and can only be performed for short periods

teacher poses a question and gives wait time
teacher calls on a student and asks them “pass or play?”
student says “play” if they wish to answer the question or “pass to__________” if they want to pass to a specific classmate
teacher provides feedback

7. The Circulatory System
Purpose: to deliver oxygen and nutrients to the cells of the body and to remove carbon dioxide and other waste products from the cells
Blood moves through arteries, capillaries and veins to transport these substances
The heart serves as the pump to circulate the blood through the circulatory system and the lungs
The gases are exchanged through the alveoli surrounded by capillaries
Training allows the circulatory and respiratory systems to get oxygen and nutrients to cells more efficiently

9. Benefits of Training 1. Decreased resting heart rate
2. Increased blood volume, red blood cells and hemoglobin (binds with oxygen)
3. Decreased recovery time
4. Increased number of capillaries→ more efficient exchange of O2, CO2 and nutrients
5. Decreased respiratory rate
6. Heart muscle becomes stronger → increased stroke volume / more efficient

10. Additional Benefits of Training
7. Reduced incidence of heart disease
8. Reduced amount of fat in the blood (lower LDL and higher HDL)
9. Collateral circulation is developed – more likely to avoid or recover from heart attack
10. Lower blood pressure
11. Reduced emotional stress
12. Control weight
13. Build muscle
14. Improve posture

11. Cardiovascular Assessments
Subject can choose between a 1.5 Mile Run Test or 3.0 Mile Walk Test
Both are easy to administer and interpret
Before administering the test:
1. Determine the length of the testing area (most high school tracks are 400M or ¼ mile)
2. Have a stopwatch available to time the subject
3. Have the subject warm up and stretch before the test
4. Instruct the subject to cover the distance in the shortest time possible
5. Have the subject cool down after the test

12. 1.5 Mile Run
Recommended for subjects who have been exercising regularly (3 or more times/week for 4+ weeks)
Length – 6 laps on a standard track (400 M)
Subject may sprint, jog, or walk, but should complete the assessment in the shortest time possible

13. 3-Mile Walk
Recommended for subjects who have not been exercising regularly
Length = 12 laps on a standard track
Subject must walk the whole time, and should complete the distance in the shortest time possible

14. Interpreting the Test
Use the cardiovascular assessment table to determine the following individuals’ fitness category :
Dale, age 22, completed the 1.5 mile run in 15:52. What is his fitness category?
Kristi, age 17, ran the 1.5 mile test in 13:23. What is her fitness category?
Linda, age 25, completed the 3-mile walk test in 41 minutes. What is her fitness category?

Predict
Write down which test you will participate in Monday, and predict your time for that test. Be prepared to share
15. Predict
teacher groups students
teacher reads a scenario
teacher asks the groups to predict the outcome
teacher has the individual student respond or may have the group designate a scribe to write their group’s response
teacher has groups share while the other groups compare/contrast their responses or teacher collects the writings 15
