How does exercise affect the heart? & bull; hello healthy

Exercise affects the heart by involving repetitive use of your large muscles, thereby activating muscle fibers programmed for endurance, and utilizing a heart rate range of 40-85 percent of your maximum heart rate. However, what makes exercise affect the heart? What factors do other activities besides sports lack? To find out the answer, let's look at some of the information below.

How does exercise affect your heart?

When you do cardio, blood flow is directed to muscles that are working a lot and away from areas that are not working too much, such as the arms or the digestive tract. With exercise, blood flow will increase and blood volume will return to the heart again. Because the heart receives a greater volume of blood, the left ventricle of the heart will adapt and enlarge. This larger cavity can hold more blood, and spray more blood per beat, even when resting.

What are the things that can be obtained from sports that cannot be obtained from other activities?

Here are the factors in sport that other activities don't have:

1. Transition

Once you start exercising, your muscles will consume more energy and produce more waste products. Because your body has to make replacement energy, your muscles need additional oxygen pumped from your heart. The amount of oxygen needed and supplied is tightly controlled by the brain, which senses the levels of waste products in the blood. The harder the muscles work, the more waste products are produced, and your brain has a bigger heart rate.

2. Stability

After your brain increases your heart rate to the point where the oxygen supply meets the demands of your muscles, your heart rate will remain high for the rest of your workout. Exercise definitely needs stability, but a highly volatile exercise will make the muscles work harder, and produce a waste product that will be felt by your brain more. And finally, it causes an increase in heart rate which can meet the increased demand for oxygen to the muscles.

3. Recovery

After you stop exercising, your muscles demand less oxygen, but the brain continues to supply additional oxygen to help with the recovery process. Some aspects of recovery, such as lactic acid, will occur within minutes, but others, such as muscle protein repair, take several hours. This means that your heart rate will remain high for several minutes or even hours after exercise, so that oxygen supply can aid recovery.

4. Exercise

When you do aerobic exercise regularly for several months or several years, the chambers of your heart can expand better, which allows the heart to fill in more blood. In addition, the walls of the heart will become thicker, so that the heart can pump stronger and more efficiently in pumping blood. Therefore, every time your heart contracts, more blood will be pumped to your muscles. The greater the intensity of exercise given, the stronger the heart provides oxygen to the body.

What about weight training?

Weightlifting affects the heart in a different way than any other exercise. At certain times, the muscles will contract and rely on two types of muscle fibers, which are responsible for giving the body big and strong. When a muscle contracts, it compresses and closes the blood vessels that flow through it. This causes an increase in blood pressure throughout the body and the heart has to use more force to push the blood out.

To compensate, the heart adjusts to increasing the thickness of the left ventricle wall which is triggered by a healthy weight training routine. In addition, exercise affects the heart by stimulating the production of new blood vessels. The more blood vessels, the more efficient the blood will flow. Exercise can increase the number of new blood vessels when lifting weights, because the size of the blood vessels also increases.
