What is the typical amount of oxygen used to replenish myoglobin stores during early recovery?

• A. About 0.5 litres.
• B. About 2 litres.
• C. About 5 litres.
• D. About 0.1 litres.

Answer: (B)

During early recovery the body works to refill the oxygen stores bound to myoglobin in the muscles. This replenishment happens quickly as part of the fast recovery processes, contributing a substantial amount to the overall oxygen debt that must be repaid after intense exercise. When you consider the total oxygen that must be restored across all active muscles, about two litres of oxygen is a typical amount needed to replenish those myoglobin stores in a healthy adult. The smaller options would understate the stores across the body's muscles, while a much larger figure would imply a much larger debt than is usually observed in the early recovery phase.
