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.
Muscle cells also contain globules of fat, which are used for energy during aerobic exercise. The aerobic energy systems take longer to produce the ATP and reach peak efficiency, and requires many more biochemical steps, but produces significantly more ATP than anaerobic glycolysis.
