Heart Rate (HR) is the BEST measure of exercise intensity in a newly tested and exercising individual.
<h3>How is HR measured in exercise?</h3>
Steps to check your heart rate during exercise:
- 15 seconds are needed to take your pulse. Put index and third fingers on y neck, to the side of the windpipe, to check the pulse over the carotid artery.
- For a beats per minute calculation, multiply this number by 4.
Monitoring your heart rate while exercising can help you shed pounds or become more effective. This is due to the fact that heart rate is a reliable gauge of exercise intensity: Your heart rate increases as the intensity increases.

Answer:
<u>Cardiac output = ejection volume X heart rate
</u>
Explanation:
CARDIAC EXPENSE, is the amount of blood that the ventricles propel every minute.
<u>
Cardiac output = ejection volume X heart rate
</u>
<u />
Cardiac output is modified by changing the volume that is expelled in each beat (<em>ejection volume or systolic volume</em>), or by changing the heart rate.
<em>The heart covers a wide range of blood flow demands. Cardiac output can range from 5 to 30 L / min, depending on the activity of the organism.</em>
