Identification of Lactate Threshold

... Identification of Lactate Threshold Introduction: The lactate threshold refers to a physiological barrier the human body encounters during exercise. During exercise the body uses oxygen as energy to power the muscles. The body uses three energy systems which provide energy for exercise, two of which are anaerobic (without oxygen) and one is aerobic (with oxygen). These anaerobic energy systems produce energy without the use of oxygen. As this is done the production of lactic acid occurs as there is no supply of oxygen to break it down in to pyruvate and Co2, and disperse it from the body. If this exercise is to continue and the production of lactate continues at a rate faster than that of which the body can remove it this is then called the Lactate Threshold, or Anaerobic Barrier. The lactate that is built up then has nowhere to go so is in and around the muscles and
