Question

Quizplus · Accepted Answer

All of the above factors are potential mechanisms that contribute to the lactate threshold. Low muscle oxygen can lead to an increased reliance on anaerobic metabolism, which produces lactate. Recruitment of fast-twitch muscle fibers also increases reliance on anaerobic metabolism and therefore lactate production. Finally, decreased lactate removal from the blood can lead to accumulation of lactate and eventual fatigue.
