Question

If aerobic exercise improves heart strength so that it pumps more blood with each beat, what likely happens to the heart rate as the cardiac muscle gets stronger?

Answer 1

Hi there!

Each heartbeat pumps a certain amount of blood to the body. As the cardiac muscle gets stronger, the amount of blood pumped with each beat increases which in turn makes the heart more efficient overall. As a result, we can infer that as the cardiac muscle gets stronger, the heart rate will decrease since it is able to pump more blood with each beat.

Answer 2

Answer:

Exercising is one of the means of improving physical health. Aerobic exercises also are known as endurance exercises like jogging, walking, and swimming, which permits contraction of muscles for longer duration without encountering with weariness. As the cardiac muscle gets robust from working out, it instigates the breathing rate as well as the heart rate. As a consequence, the heart rate upsurges. The heart gets stronger as it pumps more volume of blood.
