Definition - What does Anaerobic Threshold mean?

Anaerobic threshold refers to a physiological process of the human body characterized by an increase of lactate (lactic acid) in the blood, which occurs during high levels of intense physical activity. Ordinarily, rigorous exercise will precipitate lactate production in the blood allowing the body to effectively metabolize energy as it is released.

SureHire explains Anaerobic Threshold

Anaerobic threshold is identified by lactate (lactic acid) production in the bloodstream serving as a regulating agent during peak instances of vigorous activity. Exercise lends to a heavy concentration of lactic acid buildup in the blood, which enables a person to reach maximal capacity to execute a training drill or workout session. People will commonly experience a burning sensation in their muscles, which is the body’s terminal response to metabolize glucose into energy. Anaerobic threshold is an ultimate determinant of stamina, which will vary on an individual basis.
