Question 1: What Is Aerobic Exercise? Aerobic exercise (also known as cardiovascular exercise) is physical exercise of low to high intensity that depends mainly on the aerobic energy-generating procedure. The word "Aerobic" literally means "pertaining to, including, or requiring free oxygen", and refers to the use of oxygen to properly meet energy demands during exercise through aerobic metabolism.Generally, light-to-moderate intensity exercises that are completely supported by aerobic metabolism can be carried out for long intervals of time. Question 2: What is the difference between Aerobic and Anaerobic Exercise? Aerobic exercise and fitness can be contrasted with anaerobic exercise, of which strength training and short-distance…show more content…
What is generally called aerobic exercise might be better termed "solely aerobic", because it is designed to be low-intensity enough not to generate lactate via pyruvate fermentation, so that all carbohydrate is aerobically turned into energy. Initially during increased exertion, muscle glycogen is broken down to produce glucose, which undergoes glycolysis producing pyruvate which then reacts with oxygen (Krebs cycle, Chemiosmosis) to produce carbon dioxide and water and releases energy. If there is a shortage of oxygen (anaerobic exercise, explosive movements), carbohydrate is consumed more rapidly because the pyruvate ferments into lactate. If the intensity of the exercise exceeds the rate with which the cardiovascular system can supply muscles with oxygen, it results in buildup of lactate and quickly makes it impossible to continue the exercise. Unpleasant effects of lactate buildup initially include the burning sensation in the muscles, and may eventually include nausea and even vomiting if the exercise is continued without allowing lactate to clear from the bloodstream. As glycogen levels in the muscle begin to fall, glucose is released into the bloodstream by the liver, and fat metabolism is increased so that it can fuel the aerobic pathways. Aerobic exercise may be fueled by glycogen
