Drinking plenty of water is as important as exercise or diet for good health and optimum sports performance . Blood is composed of 90 per cent water. Reduction in water levels may result in more concentrated blood, which may be susceptible to clotting. It may become less capable of delivering oxygen to the brain and muscles.
The digestive system also needs water for optimum function and joints need water for lubrication. Insufficient water intake may stress the kidneys and the liver may be forced to detoxify the toxins. When the liver is burdened, food metabolism takes a back seat. Less water also means low levels of muscle glycogen and weaker muscles.
Do not look up to thirst as an indicator. Drink water based on your activity levels. The usual eight-glasses-a-day may be insufficient for hard-training athletes and sports persons, say researchers.
