Jakarta, 'Drink before thirsty', so people are always warned not to become dehydrated (lack body fluids). Because thirst is a signal your body is dehydrated. But it is apparently not true for most of the marathon athletes are more often excess drinking water.
Marathon runners according to a recent survey that appears in the latest issue of Sports Health, nearly half of the marathon runners drinking too much during the race.
Marathon athletes generally do not know how to maintain proper hydration, but is too focused on the fear of dehydration. As a result, marathon runners who drink continuously even result in loss of sodium ions and lead to hyponatremia (water intoxication).
As reported by The New York Times, Thursday (10/06/2011), in recent years, some marathon runners die from drinking too much, a dangerous condition called hyponatremia or water intoxication. Hyponatremia is characterized by levels of sodium in the blood are low.
Drinking too much water causes sodium levels to be low. Drinking plenty of water to make a liquid such as sodium lost through sweating or urination due to too much water in the body can dilute sodium levels in the blood.
If that happens then osmosis will draw water from the blood into body cells to equalize levels of sodium and the cells were swollen. If the cells swell and it happens in the brain, the result is fatal.
Research has been conducted on marathon runners showed ignorance athletes how to drink a good rule for runners. Some runners may drink too much water or other liquids consumed. On the other hand there are also runners who drank too little water or other liquids.
The report says the majority of the runners did not know that whether the amount of water you drink is safe or not.
Most experts are now beginning to provide advice on marathon runners to drink less. The experts focused on marathon runners because hyponatremia is rare in the race with a duration lasting less than 4 hours.
Recent guidelines from the International Marathon Medical Directors Association explicitly told to drink only when thirsty. But new research suggests that, many marathon runners who do not heed these recommendations.
A second survey conducted by researchers at Loyola University Medical Center and has been published in the British Journal of Sports Medicine in June 2011. The survey reached the conclusion that, almost half of the runners may drink too much during the race that they follow.
Only half of the runners surveyed by Loyola researchers reported that they only drink when thirsty. The others drank a predetermined schedule, and nearly 10 percent told researchers that they drink as much as possible.
"Drink as much as possible is a thing that can be dangerous and contrary to the latest guidelines from the International Marathon Medical Directors Association," said Dr.. James Winger, a professor of family medicine and lead author of the study.
"The athletes said they drink when thirsty not because responding to the recommendations of experts. Most would prefer to drink more, but some athletes have experienced indigestion. Indigestion caused by drinking with higher numbers it is a condition that is more persuasive to be prevent athletes from excessive fluid intake, "said Dr.. Winger.
"The conclusion that can be drawn from these studies it is advisable to drink when the body needs, which can be marked when we feel thirsty. This is a great way to protect yourself against hyponatremia and also against dehydration. Haus is a highly precise indicators that can describe the body's hydration status the truth, "said Dr.. Winger.
