Question

Quizplus · Accepted Answer

The term "oxygen debt" refers to the additional oxygen that must be consumed during the recovery period in order to restore the body to its normal, pre-exertion state. This additional oxygen is needed to break down any lactic acid that has accumulated in the muscles during the period of intense activity. Once the lactic acid has been broken down, the body can return to its normal metabolic processes, fueling cells with glucose and relying primarily on aerobic respiration.
