Step 1
Evaluate the time needed for lactic acid breakdown
Answer
Trained athletes typically experience lactic acid build-up during intense anaerobic activity, which requires time for the body to metabolize and clear the lactic acid post-exercise.
Studies indicate that trained individuals can clear lactic acid rapidly. Generally, the process of lactic acid regeneration back into glucose can take anywhere from 20 to 120 minutes. Therefore, the most appropriate answer to this question is:
(B) 20–120 minutes.
