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.
Anaerobic respiration occurs during high-intensity exercises when your body works so hard there is a shortage of oxygen for energy consumption. Due to the shortage of oxygen, your body breaks down glucose and phosphates stored in your muscles for energy. The byproduct is lactic acid, which causes muscle fatigue. Due to lactic acid buildup, your muscles can only sustain anaerobic respiration for short periods of time.
