They are not categorical (like male and female), that are not discrete (like number of people in a single car; you would not typically think about 3.5 people in a car).
Aerobic exercise. Aerobic exercise means that muscles use up a lot of glucose as a fuel and tends to lower blood glucose levels. Anaerobic exercise involves higher rates of muscle contraction for shorter periods of time.naerobic exercise uses different body systems to generate fuel and is usually associated with release of chemicals (counter-regulatory hormones) that block the action of insulin and turn the liver on to make more glucose â this can mean that this type of exercise causes blood glucose levels to rise.
During aerobic activity the body uses other resources such as carbohydrates and fats from the glucose in your muscles, liver, and blood to make Adenosine Triphosphates. The increased blood flow produced during muscle contraction optimizes energy usage for both aerobic and anaerobic activities. Aerobic vs Anaerobic. At rest our body uses aerobic metabolism to fuel our body with energy. As we gradually start to exercise and slowly increase demand we can maintain use of aerobic energy production. As intensity increases we get to a point where we start feeling fatigue and anaerobic metabolism begins.
