Regulated blood pressure. Improved circulation. Staying hydrated also improves blood flow and circulation and thus the delivery of oxygen and nutrients to working muscles.
Good hydration also helps remove metabolic by-products and waste from muscles, while replacing the water that is lost through sweat. How can proper hydration help young athletes reduce injury risk? Recommended daily water intake for athletes Fluid needs vary based on activity, intensity, environmental conditions, body size of the athlete and training status.
Calculating sweat rate Knowing an athlete's sweat rate is important when monitoring hydration. Water or sports drink: What is best for athletes?
Sports drinks may be recommended in certain situations including when: Exercise lasts longer than 1 hour Engaging in intense workouts Practicing or playing in extreme environmental conditions, such as high heat and humidity Excessive sweating occurs, i.
It included the statement:. During exercise, athletes should start drinking early and at regular intervals in an attempt to consume fluids at a rate sufficient to replace all the water lost through sweating or consume the maximal amount that can be tolerated.
Other examples include the High Carb vs Low Carb diet debate and Cushioned, Supportive running shoes vs Barefoot Running.
We struggle with grey areas, even though that tends to be where the answers to complicated questions often reside! He uncovered a growing number of cases of hyponatremia - a sometimes fatal condition characterised by low blood sodium levels - in an increasing number of endurance athletes who had seemingly followed advice to drink as much as they could.
In this he suggests that hyponatremia has become a significant problem largely because of the marketing efforts of the sports drink industry. He makes the tragic point that there have been a number of preventable deaths from over-drinking and that these could have been avoided with more balanced messaging.

He argues, quite compellingly, that the human body is designed to optimize its own hydration levels so, if you drink to thirst, that is basically all you need to know about hydration. End of story. This approach has merit in many circumstances. This is most likely to be the case during ultra-distance events, where total sweat losses can be significant over a long period of time, especially in the heat.
Maybe because of the human tendency towards tribalism, there are currently two opposing camps in hydration science. At the sharp end, it seems that opinion is moving towards a view that, whilst drinking to thirst is a sensible approach for shorter or lighter activities, during very long events in the heat, when total sweat and electrolyte losses are high, replenishment might need to be approached more proactively than would be the case in shorter bouts of activity.
Examples of the efficacy of this approach include this study by researchers in Spain, which showed faster racing times for athletes given salt supplements during a middle distance triathlon compared to a control group given placebos.
Drinking to thirst is likely to be a good approach in day to day life, or endurance training completed at a very low intensity. far more than I replace after my thirst response has kicked in, and so inevitably have to slow my speed as my blood volume continues to decline.
When drinking to thirst, I can lose Drink fluids throughout the day. Carry your water bottle or stop by the water fountain between classes. Do not drink a large volume of fluid right before an event or physical activity.
This may not fully hydrate or rehydrate the athlete. This may cause stomach discomfort or a trip to the restroom during the event.

We also asked Sarah Crowley, who came 3rd at the IRONMAN World Champs and was the IRONMAN South America Champion, for her opinion on how best to approach hydration planning based on her own experiences Initially I had no idea what I needed to stay hydrated for long course triathlons, having come from ITU.
I raced with one gel and a bottle of sports drink in my first It ended badly. After the race I got some good advice. It was to basically work out my general hydration and fuelling needs based on my weight and expected race times. I was also given some general advice to eat and drink at regular intervals.
I took this advice and repeatedly practiced and refined what and when I ate and drank by systematically testing different things during brick training sessions over a period of two years! People often asked me what I ate and drank, so I told them.
I am constantly refining this. Other scenarios where a pre-planned, but flexible and personalised, approach might be beneficial include Hopefully this brief summary of a hundred years or so of hydration advice leaves you in an informed position from which you can start understanding your own individual hydration needs and refine your strategy from there.

After exercising, drink 24 ounces of water for every pound of water weight you lose during your workout. Knowing an athlete's sweat rate is important when monitoring hydration. Sweat rate is the amount or rate at which a person sweats. To calculate sweat rate, measure weight before and after a workout. The difference in the weight indicates how well the athlete is staying hydrated and whether it's within the healthy guidelines. The weight difference plus any fluids consumed during workout equals the sweat rate. Understanding this number will guide the amount of fluid needed during the workouts or practices. If young athletes are working out for one hour or less, water is generally sufficient to keep hydrated. Sports drinks may be recommended in certain situations including when:.

Monitoring sweat rates are a great way for athletes to determine the correct amount of fluid they need after exercise to rehydrate. Athletes will generally sweat more in hotter conditions and climates, therefore needing to drink more to rehydrate during and after training. Having a sweat patch test done during training helps to accurately analyze your total sweat and sodium losses so you know how much and what type of drinks you need to consume to stay fully hydrated to maximize performance. Water is important for hydration but you can have too much of a good thing, meaning that drinking too much water can be detrimental to sports performance. Drinking too much water can create an imbalance between the amount of water and sodium in your body, which can lead to Hyponatremia. Athletes will be okay only drinking water for shorter training sessions, typically 1 hour or less. Dehydration causes: 1 Premature fatigue 2 increased heart rate 3 impaired thermoregulation 4 reduced concentration and cognitive function 5 greater reliance on muscle glycogen for energy 6 higher RPE 7 joint stiffness. Sweat is made up of water but also contains vital electrolytes such as sodium, potassium, and chloride. Consuming drinks or supplements that contain these electrolytes helps to rehydrate better than water alone. Water is irreplaceable. Sports drinks can be beneficial if you use them to complement water instead of using them to substitute water. The main ingredient of sports drinks is water, but the addition of electrolytes and carbohydrates make them a good energy drink during intense training sessions. Drinking enough fluids to ensure your urine is a clear color and you are well hydrated before training is key. A good rule of thumb is to drink ml two hours before exercise. So long as you are well hydrated before you start training, you can drink to thirst for sessions less than 2 hours long. On the other hand, some sports like cycling and triathlon that require strategic hydration strategies for their events will need to practice these during training to match their measured sweat rates. Measuring the changes in your body weight during training will give you a good idea of how much to drink to rehydrate. Weighing yourself before and after training to calculate your weight loss e.

| Importance of Hydration in Sport: Hydration Strategies For Athletes | Modabber ranked some of the most popular options based on "which get the job done, without including too much of what you don't necessarily need—especially sugars. Athletes need to be particularly conscientious about water intake levels, as well as electrolyte balance in order to help prevent dehydration. By paying attention to the color and concentration of your urine, and doing pre- and post-workout weigh-ins, you can develop a pretty good idea of your personal water intake needs. But, if you're concerned about dehydration or you're unsure whether you're drinking enough water, consult with a sports dietitian or a healthcare provider that specializes in sports medicine to discuss whether you can get a more personalized assessment. How much water an athlete needs depends greatly on the type of athlete in question, as well as the age, sex, and body composition of the athlete, intensity of the workout performed, and the environmental conditions where the exercise is taking place. That said, in addition to a baseline requirement of roughly 8 to 12 cups of water per day, athletes should consume an additional 3 cups of water for each pound of weight lost during the course of an exercise routine. Athletes should drink water consistently with the goal of urinating frequently with clear or almost-clear urine. Any water consumption above and beyond this barometer for euhydration could set an athlete up for hyponatremia —a condition associated with excess water intake without a simultaneous increase in electrolyte intake, resulting in a potentially life-threatening electrolyte imbalance. An athlete shouldn't continue to force water consumption beyond what has been deemed appropriate for their personal needs. In addition to consistently drinking water throughout the day, athletes can also turn to other foods and liquids to help ensure they're staying hydrated. Fruit juices, smoothies, electrolyte drinks, and even fruits, vegetables, and water-based soups all contribute to total fluid intake. Geological Survey. The water in you: water and the human body.
