Oxygen debt
Biology · Secondary 3 · Medium · Oxygen debt
After a 400 m sprint, an athlete continues to breathe deeply for several minutes while resting. This is mainly to
- supply oxygen to break down lactic acid formed in the muscles
- store extra oxygen in the liver for future exercise
- convert carbon dioxide back into oxygen in the lungs
- increase the rate of anaerobic respiration in the muscles
