Which statement about lactate threshold and endurance is true?

• A. Lactate threshold is not influenced by training.
• B. It occurs at a higher percentage of VO2 max after training.
• C. It is unrelated to fatigue.
• D. It can only be improved by lowering training intensity.

Answer: (B)

Lactate threshold rises with endurance training, meaning you can work harder before lactate starts to accumulate rapidly. After training, the body becomes more efficient at delivering and using oxygen, and it clears lactate more effectively. This combination shifts the point at which lactate builds up to a higher percentage of VO2 max, so the threshold occurs later as fitness improves. That's why the true statement is that it occurs at a higher percentage of VO2 max after training. The other ideas don’t fit because training does influence the threshold, lactate buildup is closely linked to fatigue, and improvements come from appropriate training (often including higher-intensity work) rather than only lowering training intensity.
