When you are exercising, you are breathing in oxygen (O2) and it is get the heart to pump more blood to your body
your heart pumps blood
After
Your heart has to pump more blood through your veins because of the energy you are using to exercise so your heart has to pump faster and harder
It makes the heart pump slightly faster
Certainly! Swimming is an aerobic exercise and strengthens the heart.
Absolutely. When you get your heart racing during (typically aerobic) exercise, you increase its ability to pump blood.
increases the heart rate
Because the heart has to pump more oxygen than usual to your muscles
when you exercise, your heart rate increases. the more explosive and intense the exercise, the higher the rate will go. As with any muscle in the body, exercise makes it stronger. a stronger heart allows for more blood and oxygen to circulate with each pump resulting in your heart rate lowering not only during exercise but in daily life. a lower heart rate means your heart does not have to work as hard and thats a good thing !!!
To pump blood quickly for the body because the will be needing enough oxygen during the exercise
Regular exercise strengthens your heart muscle by increasing its efficiency, allowing it to pump blood more effectively with each beat. It also improves circulation, which reduces strain on the heart. Additionally, exercise can lower blood pressure and cholesterol levels, further promoting heart health.
During vigorous exercise the heart is moving more oxygenated blood into the muscles, so it has to pump faster.
