Marathon nutrition: Everything you need to know 9 min read. Goulet, E. However, as a general rule of thumb, consuming ml to ml of water an hour should suffice. Water is one of the most important nutrients your body needs to function optimally.

Hydration strategies -

Subjects drank either cold water 39° F or room-temperature 72° F water in the two trials. Researchers also found that drinking cold water improved performance in the broad jump among 49 percent of participants, while 51 percent improved their performance in the endurance test; however, these improvements were not considered statistically significant.

Bench press performance actually went down a bit from The effect size calculation indicates this was only a small or negligible effect La Fata et al.

Another study Byrne et al. Seven year-old male recreational cyclists consumed about 30 ounces almost 4 cups of either cold 36° F or warm ° F flavored water over a period of 35 minutes of pre-exercise rest.

Among those who drank the cold water, body temperature was lower both before starting and after five to 25 minutes of activity. These subjects also cycled farther and their mean power output was greater in comparison to those who drank the warm water.

Skin temperature, lactate, heart rate, perceived exertion and sweat loss, however, did not differ between the two groups. While the exact mechanism is not known, it is suspected that brain temperature, internal thermoreception and sensory responses may be involved.

Yet another study looked at the influence of beverage temperature on the palatability or how good it tasted to the exerciser.

The more palatable a drink is, the greater the likelihood that someone will consume it. In all the studies reviewed, consuming either cold ° F or cool ° F fluids during activity was preferred to drinking warm fluids.

The analysis showed that participants would consume about 50 percent more fluid during exercise when given cold or cool fluids. Colder water is better for both performance gains and for keeping you and your clients going longer in hot conditions.

And this applies to both before and during the exercise session, particularly for longer workouts. In an article published in Nutrition Reviews, Eric Goulet asserts that hydration strategies become even more important when endurance exercise exceeds one hour.

Previous studies have demonstrated that it only takes a 3 percent reduction in body weight for performance to be significantly decreased.

The type of fluid one uses to hydrate should be based, at least in part, on the duration of the event. The American Council on Exercise advises pre-loading with an electrolyte solution two hours before an endurance event or long-duration workout, and then switching to water immediately before starting.

Be careful not to hydrate to the point of getting stomach cramps, which is often a spasm of the thoracic tendons. If the event or workout lasts less than an hour, water is all that is needed. If the event is 60 to 90 minutes in duration, then some electrolyte replacement is advised.

If the event goes into the to minute range, electrolytes and carbohydrates should be replenished. And, if the event or workout exceeds two hours, you probably need to consider utilizing all the previously mentioned items, plus some amino acids, particularly branched-chain amino acids, especially if glycogen depletion is likely Antonio and Stout, So remember, to help you and your clients keep your cool during hot and heavy workouts, keep drinking cold fluids about every 15 to 20 minutes.

Antonio, J. and Stout, J. Sports Supplements. Burdon, C. Since sweat rate differs for each individual based on acclimatization level, fitness, gender, protective equipment, etc. The rule-of-thumb is for athletes to consume about ml of fluid every 15 minutes during exercise. This is enough fluid to replace an individual with one liter per hour sweat rate, however an athlete who drank this amount during practice and had a higher sweat rate would still become dehydrated over time, which is why a universal recommendation is difficult.

The first step to ensure athletes do not become dehydrated is to have the proper supplies in place. The following are KSI-suggested items to have on hand to promote hydration during sports activities.

Being dehydrated will affect normal sweat rate. Take a nude body weight before the workout. Exercise for one hour type and intensity of exercise should be similar to the conditions in which knowledge of sweat rate is needed. During the one hour workout refrain from drinking fluids as this will affect sweat rate.

If water is consumed, weigh the water before and after the workout to determine the difference. After the workout take another nude body weight and calculate the difference between pre and post exercise. If water is consumed during exercise subtract the water weight from the post exercise weight.

Every 2. For heavy sweaters it is not uncommon to be unable to drink everything they lose during the workout. Full replacement of fluid losses may not be able to occur until after exercise.

How Much Do I Need to Drink After Exercise? Use this calculation to adequately replace fluid post exercise, following the guidelines stated previously Pre exercise wt kg — post exercise wt kg x 1. This product is only an example of the different hydration units.

They can easily squirt into the mouth so it never has to touch the lips if they are shared. Always pack at least one extra water bottle in case you lose or drop one and some easy-to-eat food such as honey or vegemite sandwiches, bananas, or a sports gel if you're able to eat.

Start your training session or event in a well hydrated state. Start drinking early and drink regularly throughout your event such as every mins. The longer you wait, the more likely it is that your gut will not absorb fluid as readily as the blood supply will get diverted from the stomach to the exercising muscles.

Keeping a small "bolus" of fluid in the stomach helps with absorption of the fluid. Shirreffs SM, Casa DJ, Carter R. Fluid needs for training and competition in athletics.

Strength and Life-threatening risks of extreme diets events are generally less affected than endurance events, but Hydration strategies in Improved cognitive abilities sports that involve repeated intense efforts will be impaired. Mild hypohydration is not harmful, but many athletes begin exercise already hypohydrated. Athletes are encouraged to begin exercise well hydrated and - where opportunities exist - to consume fluid during exercise to limit water and salt deficits. In high-intensity efforts, there is no need, and may be no opportunity, to drink during competition.
