  Fluid replacement - Wikipedia, the free encyclopedia
Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes.
In severe dehydration, intravenous fluid replacement is preferred, and may be lifesaving.
The third space where bodily fluid resides is the interstitial space, or the space between the cells within the tissues.

Fluids should be readily available and served in containers that allow adequate volumes to be ingested with ease and with minimal interruption of exercise.
It is therefore reasonable to surmise that fluid replacement that offsets dehydration and excessive elevation in body heat during exercise may be instrumental in reducing the risk of thermal injury (37).
Although the impact of fluid deficits on cardiovascular function and thermoregulation is evident, the extent to which exercise performance is altered by fluid replacement remains unclear.

Fluid ingestion equal to the rate of sweating was more effective than voluntary or partial fluid replacement (Bean and Eichna, 1943; Eichna et al., 1945; Pitts et al., 1944).
The primary benefit of sufficient fluid replacement during exercise is that it helps to maintain cardiac output and allows blood flow to the skin to increase to high levels so as to promote heat dissipation from the skin, thereby preventing excessive storage of body heat (Montain and Coyle, 1992a).
Fluid replacement does help to prevent loss of water from the blood plasma, but in endurance-trained athletes, this improved maintenance of plasma volume apparently does not by itself increase blood flow to the skin to reduce core temperature (Montain and Coyle, 199b).

 Fluid replacement
And fluids are a vital part of proper nutrition.Whether you're an elite marathon runner, rower or cyclist, or simply work out a couple of times a week in the gym or local health club, it is a virtual certainty that some sort of fluid replacement will improve your performance.
Correct fluid replacement is essential for training just as much as competition, although more attention tends to be given to the latter.
It is customary to take on fluid during official breaks in the game such as half-time in soccer or change-overs in tennis but this should be the minimum, especially in a warm environment.

Restricting fluids during exercise could actually cause a DECREASE in the athlete's performance, and could cause serious medical problems to an athlete.
This is needed to replace water excreted via urine (1.3 quarts), the skin (0.85 quart by perspiration), and the lungs (0.35 quarts by exhaled air).
With vigorous exercise, there will be an increase in the loss of fluid from the skin (from up to 3.0 to 5.0 quarts) and from the lungs (up to 0.7 quarts).

 UpToDate Fluid replacement in volume depletion in adults
There are two major issues that must be addressed when instituting fluid replacement therapy: the type of fluid that is given; and the rate of volume replacement [1].
The type of fluid given is largely dependent upon the type of fluid that has been lost and any concurrent fluid and electrolyte disorders [1].
The choice of replacement fluid in hypernatremia, for example, depends upon the source of fluid loss: dextrose and water alone can be given if there has only been water loss (as in diabetes insipidus), whereas a hypotonic saline solution should be administered in patients who have lost both salt and water (as with diarrhea).

The only way to prevent heat stroke is to drink sufficient fluid before and during the activity, rest in the shade when tired, and wear lightweight clothing that allows evaporation.
For noncompetitive, everyday active people, plain cool water is recommended, especially in warm weather, for two reasons: it rapidly leaves the digestive tract to enter the tissues where it is needed, and it cools the body from the inside out.

For events requiring a high rate of fluid intake, it is ideal to drink fluids with less than 7% carbohydrate to optimize fluid delivery and sustain hydration.
Fluids with salt (sodium chloride) are beneficial to increasing thirst and voluntary fluid intake and offsetting the amount lost in sweat.
Replacing fluids with a beverage that has less than 8% carbohydrate assures the fastest rate of fluid absorption.

 GUIDELINES FOR FLUID REPLACEMENT DURING MARATHON RUNNING   (Site not responding. Last check: 2007-10-13)
This contrasts to the currently popular dogma which holds that thirst is an inadequate index of the fluid requirements during exercise, and thus athletes who drink only in response to their thirst will become sufficiently dehydrated during exercise that their performances will be impaired and their health placed at risk.
Athlete interview evidence suggests that world-class runners ingest minimal fluid volume during their competitive races, primarily because of the difficulty of such ingestion when racing at the high exercise intensities (~85% of maximum oxygen consumption) and fast running speeds necessary to achieve success in top-level races.
Among those who develop the hyponatraemia of exercise, the rates of fluid ingestion during exercise are very much higher and may be as high as 1.5 liters per hour (7-9,44).
