To make your body and it's tissues work normally, our bodies and muscles needs as much OXygen as we can process. However the pollution of the atmosphere and the deteriorating ecology reduce the amount of oxygen we breath. The rational for Oxygen during exercise is the knowledge that during exercise, the rate of Oxygen to working muscles does not satisfy the demand.  By breathing in extra oxygen during exercise an athletes can exercise for longer periods when you take oxygen as you exercise. Even for simple home work out, extra oxygen can and will help you to have a more intense workout. Full contact games produce quick, high intensity bursts of energy. Athletes are under physical and mental stress combined with aerobic and anaerobic activity. There bodies emit more carbon dioxide than they emit oxygen. Mental fatigue occur. They are some of the best conditioned athletes in the world yet many football players choose to use oxygen to recover faster, and to stay fresh physically and mentally till the conclusion of the game. Our bodies are naturally programed to work at peak performance if we are well saturated with Oxygen. To order or view our oxygen products just visit our web site. www.oxygengirls.ca
