Explain the physiological advantage of a high concentration of myoglobin in skeletal muscles

Myoglobin has a higher affinity for oxygen compared to haemoglobin. It holds onto its oxygen and only release it when the oxygen partial pressures have become very low. As a result, it acts as an oxygen store, releasing its oxygen to the issue when oxyhaemoglobin becomes depleted (as during exercise)
