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 RateYour 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 systemHeartPumps blood to the bodyArteriesThe 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 cholesterolLDL 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 4:1).
12Cardiovascular Fitness Fact Six Cont. VeinsThe 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 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 activitiesequipment 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 ObjectiveThe objective of this test is to monitor the development of the athlete's cardiovascular system.Required ResourcesGym bench (45cm high)Stop watchAssistantHow to conduct the testStep 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 paceOne minute after finishing the test take your pulse rate (bpm)- Pulse 1Two minutes after finishing the test take your pulse rate (bpm) - Pulse 2Three minutes after finishing the test take your pulse rate (bpm) - Pulse 3Use the calculator below to determine your level of fitness
18Building Cardiovascular Fitness Today’s 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 Frequency3 time per week (minimum)IntensityHeart rate between 120 and 140 for the 30 minutes to get cardiovascular gainHeart rates higher then 140 moves to anaerobic exercise.Heart rates below 120 do not provide in signficant increase in fitness.Time30 minutes (minimum)
