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.
Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen. Anaerobic respiration in muscles. Glucose is not completely broken down, so much less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
