Sport Science: Hydration

Hydration for athletes -

As dehydration increases, there is a reduction in physical and mental performance. There is an increase in heart rate and body temperature, and an increased perception of how hard the exercise feels, especially when exercising in the heat.

Impaired skill level can also occur, along with mental fatigue that can impact concentration and decision making. Dehydration can also increase the risk of nausea, vomiting, diarrhoea and other gastro-intestinal problems during and after exercise. In cool weather or when the exercise intensity is low, sweat losses may be small.

Drinking more fluid than necessary has the potential to interfere with performance and can be dangerous to health in several ways. Over-hydration during exercise is called hyponatraemia dilute levels of sodium in the bloodstream. When you exercise for longer than 90 minutes, you're placing additional stress on your systems, and you're losing a significant amount of water and electrolytes through sweat.

For shorter workouts, the electrolyte loss is unlikely to be significant enough to impact performance. You can restore the losses more easily following your workout by consuming water and a normal diet. But when you start logging those extra-long workouts, your body is likely to need a boost of electrolytes in addition to water alone.

When you exercise in heat , your body uses it's natural cooling system—sweat—to keep your body temperature from rising. That means the workouts you do on hot days result in greater fluid and electrolyte loss.

If you're exercising in the heat, particularly if you're exercising for longer than 60 to 90 minutes, it is best to add some carbohydrates and electrolytes to your fluid consumption to prevent dehydration and immunosuppressive effects of intense exercise.

Doing so, will ensure you keep your system hydrated and balanced. You may not have ever thought about it, but exercising at higher altitudes results in more fluid loss, not only through sweat loss which remains similar to the loss you might experience at sea level , but through increased loss of respiratory water.

This loss occurs because the air is thinner at higher altitudes and you have to breath at a faster rate to intake the same level of oxygen as you would at lower altitudes.

The result is that you expire more water into the air. Plus, the physiological changes that take place when exposed to high altitudes for a brief period of time when you haven't acclimated to the environment , also affect how your body responds to exercise.

All of these factors combined add up to a situation where you might benefit from electrolyte intake as you rehydrate. Finally, any athlete who is experiencing greater fluid losses for any other reason should also consider using an electrolyte-enhanced fluid as part of the rehydration plan.

This includes athletes with injuries, medical conditions, or illnesses—particularly if diarrhea or vomiting are involved.

It is particularly important to pay attention to electrolyte balance in any situation where dehydration is more likely to occur with exercise. To help you decide which drinks to use, Dr. 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.

For reference purposes, a reliable report published by the Institute of Medicine IOM in suggests that adult women should consume about 2. Athletes need considerably more water than non-athletes!!!

O n average, female athletes should consume about 16oz water bottles ~8. M ale athletes should consume about 16oz water bottles ~ Notably, most of us athletes and non-athletes would have a hard time drinking this much water every day. The point is to drink A LOT of water to keep your body hydrated properly; especially for sport.

Proper hydration starts before you hit the court, field or gym. Start off your training sessions or competitions with all the fluids you need to perform safely and at your best. The goal is to have regular urinations that are light yellow in color.

However, energy drinks and sports drinks claim to improve energy levels, increase resistance and endurance, and improve performance. Energy drinks may contain caffeine which helps to promote alertness for improved energy levels and sports performance during intensive training and competition.

Caffeine has been shown to increase energy and fight muscle fatigue amongst adults. In conclusion, you might benefit from moderate consumption of either sports drinks or caffeinated drinks like coffee before training. Also, Learn about Is Diet Coke Better Than Regular Coke?

Also, Learn: Is Caffeine a Diuretic? Staying hydrated is vital for athletes who undertake larger than normal volumes of training, and therefore must drink a lot more fluids to match that loss through sweat.

Dehydration impairs performance and therefore must be avoided to maintain training intensity. Normal people who go to the gym and exercise frequently also need to prioritize hydration. Athletes can measure their hydration status by analyzing their urine color and frequency of urination.

Urine should be a clear, straw-like color to show good hydration levels, and going more frequently, whereas a darker yellow color, stronger smell, and going less often suggest dehydration. Drinks that are classed as diuretics, mainly alcohol and caffeinated drinks over ~mg, may be linked to dehydration.

A urine color test is a very reliable and practical way of assessing hydration status. 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.

This will be different for everyone based on their body weight and activity levels, but a good daily target is to consume 30ml per kg of body mass, plus an extra ml-1L per hour of exercise. When playing sport it is important to stay well hydrated. Hydration is ensuring the body has sufficient water to do its basic everyday functions properly i.

transport blood around the body. Sports drinks contain electrolytes like sodium which can help the body to better retain water when exercise lasts longer than 90 minutes. Athletes should aim to drink approx 0. Being hydrated helps the body to cool down more effectively.

It also lubricates joints, supports brain function and aids the transport of oxygen and nutrients to the working muscles, all of which are impaired in a dehydrated state.

In our example, this would be around ounces of fluid containing sodium. During exercise How much fluid you need depends on how much you sweat. Try to drink about ounces of fluid every 15 minutes for a total of ounces per hour. After exercise If appropriate, you can weigh yourself before and after your workout, and drink ounces of fluid for every 1 pound lost.

This can help you stay hydrated without needing to weigh yourself. Is it enough to just drink when you feel thirsty? Can you drink too much water? Official healthcare provider. Kansas City Chiefs.

The changes over time has been most clearly documented in the writings of Prof. Tim Noakes, along with two prominent ex-sports science students from his department at the University of Cape Town; Ross Tucker and Jonathan Dugas.

Their research into hydration concluded that, in the early s, it was considered best practice to advise athletes to drink nothing, or as little as possible, during all athletic pursuits.

Four small bottles for a long stage of the Tour, it is frowned upon to drink more. Avoid drinking when racing, especially in hot weather. Drink as little as possible, and with the liquid not too cold. It is only a question of will power. The hypothesis was that this fatigue was often being caused by a combination of carbohydrate depletion, dehydration and electrolyte loss.

So a drink formulated with sugar, salts and water was developed and found to be remarkably effective. Image credit: Ethan McArthur via Unsplash Copyright free. Many of these studies appeared to demonstrate that dehydration was a serious performance limiter, especially during endurance sports in the heat.

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.
