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.
Metabolism of carbohydrates in muscle. Energy production, that is ATP synthesis from ADP and Pi, can occur anaerobically (without use of oxygen) or aerobically (using mitochondrial reactions and oxygen). Use of ATP does not lead to major decreases in ATP levels, due to its rapid resynthesis. Extreme activity leads to no more than a 20% reduction in ATP concentration in muscles. Anaerobic glycolysis is far more rapid than aerobic metabolism.
