How does exercicise affect the pulse rate?

Answer 1

Cardiac output increases with exercise, this is mainly due to the increase in heart rate (HR), but also stroke volume (SV). remember the formula:

CO = HR * SV

Ventricular End Diastolic Volume (EDV) is maintained until maximal heart rate by a combination of increased atrial contraction and active relaxation of the ventricle. Increased beta agonism causes an increased SV for a given EDV.

At very high heart rates (typically over 180 ish depending on the individual) SV starts to fall due to the inability of the heart to compensate for the reduced diastolic filling time. The heart is also very dependant on atrial contraction, with increased exercise, and if the subject is not in sinus rhythm they will decompensate much sooner.

Athletes have a higher cardiac output mainly due to increased stroke volume.

Answer 2

Exercise not only trains muscle and tissue. It also trains the heart. During intense exercise, such as HIIT (High Intensity Interval Training) or LISS (Low Intensity Steady State), the heart is forced to operate at an elevated level. Just like building muscle over time with resistance training, the heart will learn to operate more efficiently. The end result is the resting heart rate (RHR) being reduced.

Answer 3

It is your body's way of getting more oxygen to your muscles.

Answer 4

Blood pressure is increased to surply the oxygenated blood to cells that are metabolising and carrying the deoxygenated to the lungs to be oxygenated.

Answer 5

Your pulse rate will get higher when you exercise because the heart is pumping more oxygenated blood to the body

Answer 6

exercise, if someone scares you, sports, your health mostly. a slow pulse rate (this is what my health teacher says) is good . a fast pulse means you probly aren't exercising or it's genetic.

Answer 7

If the pulse starts beating very fast , then there are chances that the body is having trouble.

Answer 8

If you are in good shape it will not affect you pulse rate- for overwieght or diseased people there pulse rate will increase
