| Some important facts about oxygen Oxygen is a necessary component in every chemical reaction important to human physiology. We can survive without water for a few days and without food for literally weeks but without oxygen we can only live for a few minutes. Nutrients in our bodies, such as proteins, carbohydrates and fats must have a constant supply of oxygen to convert "potential" energy to "usable" energy. Physical Stress consumes large quantities of oxygen and, therefore, reduces the supply to numerous cells and tissues throughout the body. New Zealanders are renowned worldwide for their high participation rates and achievements in sport, and for their strong anti-drug stance. Proper oxygenation allows the body to produce and supply ATP to the muscles, giving them strength and elasticity. A lack of oxygen (hypoxia) causes the body to produce an oxygen-deficient form of ATP called lactic acid. This reduces the efficiency of muscles and can lead to cramps, pulls, strains, etc. |
