The Benefits of Cardiovascular Exercise (Part II)

5. An increase in the number and increase in size of mitochondria. All energy necessary for cell function is produced in the mitochondria. As the size and number increase, so does the potential to produce energy for muscular work.

6. An increase in the number  of functional capillaries. These smaller vessels allow for the exchange of oxygen and carbon dioxide between the blood and the cells. As more vessels open up, a greater amount of gas exchange can take place, thereby decreasing the onset of fatigue during prolonged exercise. This increase in capillaries also speeds up the rate at which waste products of cell metabolism can be removed. Increased capillarization is also seen in the heart, which enhances the oxygen delivery capacity to the heart muscle itself.

7 .A decrease in recovery time. Trained individuals enjoy a faster recovery time following exercise. A fit system is able to restore at a greater speed any internal equilibrium disrupted during exercise.

8. A decrease in blood pressure and blood lipids. A regular aerobic exercise program will cause a reduction in blood pressure and fats such as cholesterol and triglycerides, all of which have been linked to the formation of atherosclerotic plaque, which obstructs the arteries. This reduction decreases the risk of coronary heart disease. High blood pressure is also a leading risk factor for strokes.

9. An increase in fat-burning enzymes. The role of these enzymes is significant, because fat can be lost only by burning it in muscle. As the concentration of the enzymes increases, so does the ability to burn fat. 

Engaging in a regular routine of cardiovascular exercise will help you reap these benefits mentioned. You don’t have to go out and kill yourself, but you want to challenge yourself so that you can keep increasing your threshold. If you are a member of The Fitness Nut House and would like to know more about cardiovascular training just ask and I will be more than happy to help you get the most out your training program.
