Obviously should not have excessive intake of salt and sugar, so this seems to be a contradiction there. Situation what is the case? Summer time, reported repeated endlessly to prevent heat stroke. Reports will be referred to, when it's very hot, even if you don't feel thirsty, still diligently to add moisture. Also would like to guide that, because salt with water loss, so being able to add salt and water and sports drinks are the most suitable.
But when we studied the cases of heat stroke, I have two questions. The first question is, the need for water and salt intake.
The second question is, of stroke-related written information is often referred to, in order to avoid heat stroke, even if you don't feel thirsty, you still have regular hard water. And supplement use drinks the most appropriate. But theoretically, the sodium concentration in human blood, when dehydration occurs, the mouth should naturally feel thirsty. This time water is the natural response of biological, why it is necessary prior to the natural reaction, first to make a drinking behavior?
I took my questions to view the information, but no information to clearly answer the question. Until you see in July 2012, the United Kingdom's leading medical journal of the British Medical Journal, published an article entitled The truth about sports drinks (sports drinks face) interpretive reports. Finally my question, there has been a very clear answer.
Its answer is, except for special conditions and pathological conditions, and temporary dehydration, as long as the thirsty to drink water is sufficient, no need for other disposal. In other words, its opinion is in normal circumstances, there is no need to use sports drinks. See here, I think a lot of readers don't believe this view at all. But please let us hear last words. This interpretive theme is as follows. Movement or heat, environment prone to dehydration, drink a sports drink, in fact, not long ago handed down the idea.
Sports drink originally began studies in professional sports. In order to supplement the loss of moisture and heat in motion, Ion, what kind of complementary methods more appropriate to correct, and not slow motion effects, can also bring good results and good records? After the study, results of which are sports drinks.
Engaging in strenuous exercise, your body will burn calories and in the form of sweat, loss of water and ions. The concept of a sports drink, is a short period, the physical loss of carbohydrates, water, potassium, sodium, if these substances are manufactured with drinks, during exercise due to supplement it, movement efficiency might continue, and excellent performance. Under this reasoning, 1960 's, the United States launched the world's first sports drink.
The world's first sports drink became a very popular product, so are similar sports drinks have been developed around the world, making the beliefs of today's sports drinks. Japan has a similar product development sales, which we all know.
Sports drinks manufacturers have a number of researchers, and to set up research institutes, even issuing a professional magazine for science. It aims to do so through scientific data, hanging guaranteed success for beverages, beverage sales located in locations close to the pharmaceuticals.
Its strategy has been successful, then put into sports drinks manufacturers have adopted the same strategy, repeating the same campaign. Them to-"cannot protect the body of water"-advertisements, focusing on sports drinks replace water advertising.
Olympic and world sport, officially adopted this type of sports drink for drink, sponsoring Manufacturers Association has invested huge sums of money for that purpose. The effectiveness of sports drinks at this stage, at best, limited to professional sports. Supporting data for its effectiveness, is limited to manufacturers under, of the study for a professional athlete.
Later, under the leading of manufacturers, began a concept-good for athletes at the professional level, as well as for amateur athletes, sport beginners, should do no harm. Through such publicity, significantly expanded the scope of sports drinks. School it may also recommend a sports drink, and sports drinks scope to extend without limit to children and the elderly from dehydration and heat stroke prevention. But in practical terms, children and the elderly to drink sports drinks better than water is simply unfounded, there is no reliable research data to support.
In other words, "sports drinks to prevent dehydration" argument, but manufacturers for their own benefits and claims. Said it was the conditions under which the establishment of the fact that, in fact, no one knows. Then above explains reports of two literature references.
In 2005, The literature published in the New England Journal of Medicine, examined the 2002 Boston Marathon runners hyponatremia that occurs and causes.
Hyponatremia is sodium in the blood (salt) to reduce morbid. The 2002 Boston Marathon, 28-year old woman died of hyponatremia due to teams. Everybody will know from before, though not to the point of death, persistent sports such as Marathon, amateur players in particular cases of hyponatremia occurs quite often.
If the manufacturer's argument, which recommends drinking sports drinks theory, hyponatremia is a supplement as sodium shortage triggered by the phenomenon, if the supplement is not water, but use sports drinks to replenish water, hyponatremia that's not going to happen. This literature for 488 runners participating in the event, conduct blood tests, concluded 13% of hyponatremia. I hope you understand that this is quite a high percentage. Then after analyzing which players have hyponatremia, that weight gain after a game have a close relationship. Marathon consumes a tremendous amount of heat, but why weight increase?
This, of course, is the result of excessive water intake. Body of excess water and sodium in the blood, known as water intoxication. Firmly believes that sports drinks manufacturers argued that movement must add moisture, so while running a marathon, while constantly drink water instead of relative lack of salt, cause damage to the brain, the most serious and even death.
Experts suggest drinking a sports drink claims, compared with water, salty sports drinks does not lead to water intoxication, but this literature data show, intake water is pure water or sports drinks, water intoxication occurs there is no different.
In other words, even sports drinks, many will still drinking the blood of salt fades, so evolved into hyponatremia. In simple terms, if guide player: "thirsty after hard water", that is, not at the case of hyponatremia. "Thirsty after it is too late, must fix the time to add a sports drink" indicates, it has its dangers.
Professional athletes in training before they can use their bodies feel the adequacy of water supply, the risk of hyponatremia can occur. Problem is that lay novice, if in the same way, they drink a sports drink, drinking is likely too high.
Beverages suitable for professional athletes, but recommended that amateur use in the same way, I think it has its pitfalls. In 2001, the British Journal of Sports Medicine published a paper in the journal, the paper long distance riding bicycle activities, inspection of water supplement and correlation between the efficiency of movement. It was found that long bike slightly dehydrated State is most excellent. Water replenishment, get water only when thirsty ways than compulsory regular hydration more effective conclusion. In other words, the introduction of sports drinks when he began to advocate the doctrine-"early lost of water, electrolytes and carbohydrates, can improve efficiency", hereby expressly denied.
In fact more or less the dehydration, they can improve the efficiency of movement, so thirsty to add needed moisture, arguably the most physiological mechanisms of the body, and have fewer problems. To sum up
Many experts recommend, in order to prevent dehydration and heat stroke in the campaign, best time to drink a sports drink. But before the thirsty water habits, and when that sports drinks better than water views, in fact not very clear is based. In General, mild dehydration can increase physical performance, and this will naturally be thirsty when stimulated, so "thirsty before drinking water" should suffice. Thirst excessive intake of sports drinks before, and will therefore increase the risk of water intoxication. In addition, sports drinks contain a lot of salt and sugar, drink sports drinks in a row, will have elevated blood sugar, salt accumulation in the body and cause health risk of edema.
Because sports drink ingredients and components are similar, so there's absolutely no eating, when perhaps it is effective and efficient to drink, but now that you have eaten dinner, yet to be drinking a sports drink, is likely to impose a burden on the body.
At this stage, I think that sports drinks are beverages, no other functions if viewed it as something healthy, in fact, is a very dangerous thing. As long as normal to eat three meals a day, even if it is hot, still do not need to give priority to sports drinks.
In order to prevent heat stroke and consume a sports drink, although by no means wrong but does not not heat stroke after drinking, therefore, let the body used to the heat, timed cooling body, relaxing the body, this is important work. Said when the sports drinks have significance? Extreme, only occurs when dehydration symptoms no eat.
