DESCRIPTION
HOW TRAINING AND FITNESS AFFECT THE HEART. 1. HEART RATE OR PULSE RATE- This is the number of times the heart beats per minute. In a trained athlete it is likely to be less than an unfit person and it is therefore heart rate that is used to indicate a person’s fitness level. - PowerPoint PPT PresentationTRANSCRIPT

1. HEART RATE OR PULSE RATE- This is the number of times the heart beats per minute.In a trained athlete it is likely to be less than an unfit person and it is therefore heart rate that is used to indicate a person’s fitness level.Heart rate can vary considerably from person to person and even within the same athlete, but 72 beats per minute is often thought of as being average.

The resting pulse rate can also be affected by: 1.Age
2.Gender 3.Size4.Posture5.Eating6.Emotion7.Body temperature8.Smoking

MAXIMUM PULSE RATE can be worked out by the formula:
220 - Age
Therefore your maximum pulse rate would be:-
220- 15
205

2. STROKE VOLUME- This is the amount of blood pumped by the heart per beat.
At rest this may be 85 ml, but when exercising it could go up to 130 ml.

3. CARDIAC OUTPUT- the amount of blood pumped by the heart in 1 minute.
This is governed by the heart rate and the stroke volume. The formula is:
cardiac output = Stroke volume x Heart rateFor example- If stroke volume was 10 mls per beat and heart rate was 70 beats per minute.
Cardiac Output would be 10 x 70
= 700

1.When a person trains regularly their stroke volume will increase.
2.On the other hand, the heart rate does not increase, it DECREASES, so the heart becomes more efficient.
3.Training increases the heart muscle in size, thickness and strength.

HOW DO WE MEASURE CARDIOVASCULAR FITNESS ?
The best measure of cardiovascular fitness is called MAXIMUM OXYGEN UPTAKE or VO2 MAX.This measures the ability of the heart, lungs and blood to transport oxygen to the muscles.
A frequently used test for this is the BEEP TEST.

ANOTHER TEST IS THE HARVARD STEP TEST.

YOU ARE AWARDED SCORES DEPENDING ON THE HEART RATE RISE AND RECOVERY.FITNESS SCORE = DURATION OF EXERCISE IN SECONDS __________________________________ X 100 2 X SUM OF RECOVERY PULSE RATES

ANOTHER TEST IS THE COOPER 12 MINUTE RUN/WALK.

WHAT IS A WORKING PULSE RATE ?
The working pulse rate is a measurement of pulse rate taken immediately after exercise.This is an accurate guide to the intensity the heart has been working. A target range (Target zone) can be set for the heart rate to reach during exercise and this can be worked out using the formula:
![Page 21: HOW TRAINING AND FITNESS AFFECT THE HEART](https://reader036.vdocuments.us/reader036/viewer/2022062520/56815fb7550346895dceb1e5/html5/thumbnails/21.jpg)
60-80% of Maximum Heart Rate
e.g. The target for a 15 year old is:
220-15 = 20560% of 205 = 12380% of 205 =164Therefore the target zone is:123-164 b.p.m.
