Oxygen debt refers to the additional oxygen consumed after working out. It encompasses the oxygen the body requires after rigorous exercise in order to restore a normal condition.
During heavy exercise, the body utilizes anaerobic metabolism, and as such, there is insufficient oxygen. Following exercise, an increased rate of breathing and heartbeat rate serves to bring additional oxygen to the muscles, eliminate accumulated lactate, and replenish ATP and phosphocreatine stores. The magnitude of oxygen debt relies on the intensity and duration of the workout. The knowledge of oxygen debt assists athletes in scheduling recovery and interval training to enhance their skills and performance.
