2Cardiovascular Fitness Objectives
- Todays Objectives
- Describe the benefits of cardiovascular fitness
to health and wellness. - Explain the relationship between physical
activity and good cardiovascular fitness. - Describe and demonstrate some methods you can use
to assess your cardiovascular fitness. - Determine how much cardiovascular fitness is
enough.
3Cardiovascular Fitness Fact One
- Cardiovascular fitness considered is the most
important fitness component because - A high level of fitness means that you have a
healthy cardiovascular system. - Cardiovascular disease is the leading cause of
death in the United States.
4Cardiovascular Fitness Fact two
- The components of the cardiovascular and
respiratory systems are - The heart, lungs, and blood vessels make up these
systems (the cardiorespiratory system). - The heart transports blood (carrying oxygen and
nutrients) around the body. - The lungs oxygenate the blood and remove carbon
dioxide.
5Cardiovascular Fitness Fact three
- Good cardio-respiratory fitness benefit each of
the following - The heart benefits by being able to pump more
blood per beat. - The lungs are able to increase the amount of
oxygen that diffuses into the blood.
6Cardiovascular Fitness Fact three cont.
- The blood can carry more oxygen to the working
muscles. - The cells adapt by being able to extract and use
more oxygen.
7Cardiovascular Fitness Fact four
- Several types of activities are likely to improve
aerobic fitness. Examples are - Aerobic activities (jogging, swimming, biking,
hiking) of a sufficient intensity and duration. - An exercise session of 20 minutes or more, at a
heart rate in the target zone, will improve
aerobic fitness.
8Cardiovascular Fitness Fact five
- The cardiovascular system benefits due to
exercise because - the stress of exercise causes adaptations
(changes) to the cardiovascular system. - the body adapts to the stress of exercise by
becoming stronger and more efficient.
9Tools to Measure Cardiovascular Fitness
- Resting Heart Rate
- Your resting heart rate is how many times your
heart beats in 1 minute while you are resting. - Resting heart rates for teenagers may range
between 60 and 90 beats per minute.
10Cardiovascular Fitness Fact Six
- Parts of the Cardiovascular system
- Heart
- Pumps blood to the body
- Arteries
- The arteries transport blood to the muscles and
organs. - The process of fatty deposits building up on the
walls of the arteries is known as
atherosclerosis.
11Cardiovascular Fitness Fact Six Cont.
- Types of cholesterol
- LDL cholesterol
- (this cholesterol damages arteries)
- HDL cholesterol
- (this cholesterol helps get rid of LDL
cholesterol) - It is important for LDL cholesterol not to be too
high, and HDL cholesterol not to be too low - (suggested ratio of no greater than 41).
12Cardiovascular Fitness Fact Six Cont.
- Veins
- The veins transport blood back to the heart.
- The one-way valves prevent the blood from flowing
backward through the circulatory system.
13Assessing Cardiovascular Fitness
- In a laboratory, a running or cycling test can
measure how much oxygen you can use when
exercising (special equipment is needed for this
test). This test is called maximal oxygen uptake.
14Assessing Cardiovascular Fitness Cont.
- On a playing field, you can complete an aerobic
run (usually one mile) in the quickest time
possible or do the walking test. - In the gymnasium, there are other aerobic tests
(step test, PACER test) that can estimate how fit
you are.
15Cardiovascular Fitness Guidelines
- Fitness Guidelines
- Aerobic exercise on a regular basis (3-5 times
per week, heart rate in the target zone, for 20
min or more) should provide you with a good level
of fitness. - Fitness standards identified with different
physical fitness test can help you see where you
currently are and see improvement over time
16Examples of Fitness rating for One mile run
- purpose
- this test measures aerobic endurance, as a
measure of health and an important component of
many sporting activities - equipment required
- stopwatch, smooth and level marked 1 mile track,
paper and pencil. - description
- The purpose of this test is to complete one mile
in the fastest possible time. After the purpose
of the test and instructions are given, the
participants begin running on the count "Ready?
Go!". If they desire, walking may be interspersed
with running, however, they should be encouraged
to cover the distance in as short a time as
possible. - scoring
- Note the time, in minutes and seconds, it took to
complete the mile. These results can be compared
to published norms for similar age groups.
17Examples of Fitness rating for Step test 17
- Objective
- The objective of this test is to monitor the
development of the athlete's cardiovascular
system. - Required Resources
- Gym bench (45cm high)
- Stop watch
- Assistant
- How to conduct the test
- Step up on to a standard gym bench once every two
seconds for five minutes (150 steps) - Have someone to help you keep to the required
pace - One minute after finishing the test take your
pulse rate (bpm)- Pulse 1 - Two minutes after finishing the test take your
pulse rate (bpm) - Pulse 2 - Three minutes after finishing the test take your
pulse rate (bpm) - Pulse 3 - Use the calculator below to determine your level
of fitness
18Building Cardiovascular Fitness
- Todays Objectives
- Explain the difference between aerobic activity
and anaerobic activity. - Describe the FIT formula for developing
cardiovascular fitness. - Explain how to determine a threshold of training
and a target zone for building cardiovascular
fitness using two different heart rate methods.
19Aerobic Cardiovascular Fitness
- Aerobic means with oxygen.
- Aerobic exercise means exercise you can sustain
for long periods of time. - Aerobic fitness is the same thing as
cardiovascular fitness.
20Anaerobic
- Anaerobic means without oxygen.
- Anaerobic exercise means exercise you can sustain
for short periods of time. - Aerobic fitness is not the same thing as
cardiovascular fitness.
21Keys to Cardiovascular
- Frequency
- 3 time per week (minimum)
- Intensity
- Heart rate between 120 and 140 for the 30 minutes
to get cardiovascular gain - Heart rates higher then 140 moves to anaerobic
exercise. - Heart rates below 120 do not provide in
signficant increase in fitness. - Time
- 30 minutes (minimum)
