Metabolic Changes - Essay Example While discussing these changes, the expose will analyze the reasons why these changes take place. A discussion on metabolic changes will not be complete without a discussion on aerobic and anaerobic exercises. In this regard, this expose will discuss the differences between aerobic and anaerobic exercises and the types of exercises involved in aerobic and anaerobic exercises. Finally, this discussion will not be complete without a discussion on the physical changes that take place in muscle fibers during exercising. Martin identified the most visible change in an individual’s respiratory system during exercises as increased minute ventilation. In this regard, it is common knowledge that the body exchanges more carbon dioxide and oxygen during physical exercises than when at rest. In line with this, these changes affect the respiratory system and the cardiovascular system during exercises. Martin indicated that the changes were a result of increased supply of oxygen due to an increase in the tissue oxygen extraction and the delivery of oxygen by the arteries. In addition, Martin noted that there was increased transportation of the carbon dioxide to the venous side. During exercises, glucose and body fats use the increased oxygen in the body to form adenosine triphosphate (ATP) that produces energy necessary for cellular reactions in the body (Martin). Martin identified the ability of the heart rate to increase immediately during exercises. In this case, the consumption of oxygen is related to the cardiac output with the stroke volume, which is the amount of volume of blood pumped from one ventricle of the heart. Effectively, this increase is responsible for the increased heart rate during exercises. In addition, the heart rate increases due to the extra cardiac output that delivers oxygen to the exercising muscles (Martin). The extra cardiac output that delivers
