Changes that occur in the body after participating in consistent prolonged exercise sessions for 6 weeks or longer.

The circulatory system, also called the cardiovascular system is involved in transporting blood around the body. The essential components of the human cardiovascular system are the heart, blood and blood vessels.

When you endure an ongoing exercise routine this will results in more work being done for your cardiovascular system (the heart). This increase of work ultimately strengths your heart and this means it can meet these demands off consistent work. Therefore when resting the heart doesn't have to work as hard to supply the body with blood while at rest.

Long term effect of an exercise on the cardiovascular system increases the blood volume. The blood volume is the amount of blood that is circulating in the body. Each beat pushes the blood throughout your body and it carries oxygen blood to tissues. If you do regular exercise it improves the strength.

A long term effect of regular exercise is the increase of the number of capillaries you have. Capillaries are the tiny blood vessels that branch off of bigger veins and arteries. They permeate organs and other tissues so that all cells and organs can get the nutrients they need. This means your body gets more efficient at taking out waste products like carbon dioxide and uses the oxygen-rich blood more effectively.

What happens to your circulatory system when exercising?

Your muscles produce lots of energy when you exercise and the circulatory system’s activity during exercise improves the supply of a fluid or oxygen and nutrients for you muscles. Regular exercise is good for you and increase the efficiency of the circulation system activity during an exercise. The muscle needs energy. Circulatory system work hard in helping the body to stay balance and maintain healthy during exercise.

The heart doesn’t take a rest. It keeps pumping up blood for 7 days a week and 24 hours each day. Lack of exercise is unhealthy diet and it could break down the heart. If you do regular exercise it keeps the heart strong so it does not work harder in circulating the blood. This is called resting heat rate.

The vascular system can redistribute blood to those tissues with the greatest immediate demand and away from areas that have less demand for oxygen.
At rest 15-20% of circulating blood supplies skeletal muscle. During vigorous exercise this increases to 80-85% of cardiac output. Blood is shunted away from major organs such as the kidneys, liver, stomach and intestines. It is then redirected to the skin to promote heat loss.

When the arterial wall remains pliant and elastic, it can withstand high blood pressure. Weak arterial wall leads to damaged or ruptured arteries. It could also cause health complications. Exercising helps keep the arterial wall elastic so the body can adapt to changes in pressure more effectively. Physical fitness also allows the heart to supply more oxygen without decreasing the cardiac output in high pressure.

The heart becomes stronger the more you exercise. When you have a strong heart you recover faster from any injury or health problems. If you’ve been exercising for years, your blood pressure remains normal. Even if your blood pressure spikes as you work out, it will go back to normal at a much faster speed. This shows an indication of good health and efficient cardiovascular system.
