How Low Oxygen Contributes To Fatigue

Oxygen is used in so many process in the body.  Every cell in the body contains mitochondria that uses oxygen to convert glucose (sugar) into energy. This process is called cell respiration.

When oxygen  falls below optimal levels such as during exercise or physical exertion normal aerobic cell respiration will switch to a less efficient method of converting glucose to energy called lactic acid fermentation. This is a type of anaerobic cell respiration which does not require oxygen. Continue reading “Oxygen In The Muscles”
