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.

Also, this disease is related to certain habits including, eating habits, sports activities, and the consumption of substances such as cigarettes and alcohol. So, the correct answer is D. Hypertension
Answer:
The correct answer to the question: An abnormal sound (murmur) due to narrowing or stenosis of the mitral valve might be heard during:____, would be, A: Diastole.
Explanation:
It is first important to know that a murmur comes from the sound the blood makes as it passes either through a hardened tissue, like is the case of stenosis of a valve, or because it leaks back from where it came, due to regurgitation, because the valve is defective and cannot close properly. During the cardiac cycle, there is a process of systole, and of diastole, that ensure the filling and expulsion of the blood inside the heart towards the body, and from the body into the heart, so that a constant flow is ensured. In the process of filling and emptying, two sets of valves, the mitral and tricuspid, and the aortic and pulmonary, open and close to allow blood flow towards the different chambers of the heart, and out into the blood vessels of the body, and prevent the blood from returning towards where it came. In the case of mitral stenosis, which is the toughening of the mitral valve of the heart, the blood flowing through it makes a murmuring sound that can be caught up through a stethoscope. This sound is prominent during diastole, and that is why medically this murmur is known as a diastolic murmur.
