Lactic acid

Lactic acid can be formed in the muscles after vigorous exercise due to anaerobic respiration. Accumulation of lactic acid creates muscle fatigue and reduces the ability of the muscles to contract.

An indication of a lactate build up is intense muscular pain, after high intensity work lasting between 10 seconds and 3 minutes - the gap between the muscles use of just ATP as an energy source, up to 10 seconds, and the use of glucose and oxygen as an aerobic source of energy.

Lactate is removed from the body over about an hour, and is aided by a dynamic cool down after exercise.
