Question

Removal of lactic acid following a bout of intense exercise is A) more rapid if the subject rests, compared to performing light exercise. B) more rapid if the subject performs heavy exercise (>70% VO₂ max), compared to rest. C) more rapid if the subject performs light exercise (~30% VO₂ max), compared to rest. D) the same whether the subject rests or performs light exercise (~30% VO₂ max).

Quizplus · Accepted Answer

Performing light exercise (~30% VO₂ max) is more beneficial in removal of lactic acid compared to rest. This is because light exercise helps in increasing the blood flow to the muscles, which helps in elimination of lactic acid from the muscles. Heavy exercise can lead to accumulation of lactic acid and further delay its removal.
