The lactate threshold is defined as:

  1. The point of maximal attainable oxygen consumption
  2. The intensity at which blood lactate rises sharply
  3. The threshold at which exercising muscles begin to ache
  4. The rate of lactate clearance from the bloodstream
Show answer and explanation

Correct answer: The intensity at which blood lactate rises sharply

Lactate threshold marks the exercise intensity at which lactate production exceeds its clearance. It is an important predictor of endurance performance.
