Blood flow to the skin also increases. The blood vessels serving the skin dilate to allow more blood to the surface of the body. This helps to cool the body down during exercise. Your blood pH—the level of acidity in your blood— becomes more acidic.

Your body uses by-products of carbon dioxide to buffer the hydrogen ions in your bloodstream. Hydrogen ions are electrically charged particles in your body.

The greater the number of hydrogen ions, the higher the acidity. Because you breathe faster during cardiovascular exercise, you expel carbon dioxide faster than you would normally. This gives the hydrogen ions time to accumulate. Decrease in resting heart rate. Because the rigors of regular exercise require so much work from the cardiovascular system, sedentary periods become even easier for the heart by comparison. The heart eventually becomes more efficient, and no longer needs to beat as quickly to supply the body with blood while at rest.

The American College of Sports Medicine encourages regular aerobic exercise as a method of controlling and reducing high blood pressure due to its effects on lowering your blood pressure. Overview Exercise has multiple short-term and long-term effects on your cardiovascular system. Heart Short-term aerobic exercise such as running for 30 minutes will not increase the size of your heart muscle, nor will it thicken the walls of your heart. Blood Vessels When you take one aerobic class, the blood vessels going to your working skeletal muscles increase in size, or dilate so more blood can flow to these muscles.

Exercise has multiple short-term and long-term effects on your cardiovascular system. Your cardiovascular system is also called the circulatory system. It is made up of your heart, arteries, your veins and capillaries.

Privacy FAQs

Long Term Effects of Exercise on the Cardiovascular System A fairly well conditioned athlete can see long term cardiovascular effects from exercising in as little as two weeks. People who are just beginning to exercise will see effects in up to four weeks.

Short term/immediate effects of exercise on the cardiovascular system Test your knowledge Question Benefits of short term effects of exercise Increased oxygen delivery to the working muscles. Increased removal of carbon dioxide Increased blood flow. During exercise, the cardiovascular system is called upon to meet the increased needs of the body in many ways. The cardiovascular system rushes oxygen to hardworking muscles, returns used blood to the lungs to be reoxygenated, and delivers fuel to the active tissues of the body.
