Hydration for sports events and competitions -
Although athletes turning up to training a bit low on fluids is relatively common, it's generally less of an issue before major competitions.
But, because most athletes care a lot about their performance in big events, there's a tendency to increase fluid intake before the big day because extra priority is placed on all aspects of last minute preparation.
The irony of this extra emphasis on pre-event hydration is that quite a lot of athletes can go from slightly under-drinking before training to significantly over- drinking pre-competition and this can lead to a different set of problems! low blood sodium levels caused by inadequately replacing the sodium lost when sweating and further dilution by drinking plain water or weak sports drinks , something that can be pretty catastrophic for health and performance if it goes unchecked.
The idea of carb loading - i. maximising the amount of glycogen you have stored in your muscles and liver before a strenuous activity - is one that's well researched and essentially universally accepted as a performance-enhancing tactic. OK, so sports scientists love to argue over exactly what and how much you should eat, and when exactly to shove it in your cake hole, but few sane athletes would argue with the principle that consuming additional carbohydrate calories often combined with a tapering off in training load in the final days before an event is a good idea.
That's because you can store up and subsequently use a lot of this energy later on when you need to dig deep and burn through large amounts of fuel during a long or hard effort.
With hydration things are less clear cut than with carbs. As we've seen, many athletes do tend to increase fluid intake prior to important events or hard training sessions, with the vague notion that having more in the tank should result in better performance.
But many unfortunately over do it in the process and this is harming their performance. But, can you actually store fluid over and above being normally hydrated and, if so, does it help to do so?
For more on why sodium is crucial to staying hydrated and maintaining your performance, you may want to read this blog. In a nutshell though, without the right amount of sodium in your pre-exercise drinks, drinking lots of water will do you a fat lot of good.
The importance of sodium to hydration and maintaining your performance was further proven by research conducted at NASA at the end of the 20th century. It was causing them to feel weak, light headed and even to black out on re-entry or once they landed back on terra firma.
To combat this, NASA tested lots of drinks containing different carbohydrates and electrolyte mixtures and found that the more sodium you put in a drink, the more effective the drink would be at being retained in the body and bloodstream and correcting dehydration. This review article essentially came to the same conclusion as NASA that sodium preloading with a drink strong enough to stimulate fluid retention in the blood stream, but not so strong that it caused other knock on issues, does seem to improve endurance performance.
At the other extreme, most of the scientific studies that have been conducted in this area have looked at using extremely strong electrolyte drinks containing ~3,mg of sodium per litre. That's like drinking a bag of saline solution that would normally be put into you via an IV!
The athletes drank a set amount 17ml per kg of body weight, so about 1. If you have any questions about how to preload effectively or need help optimising your approach, drop us an email.

But they should be the baseline levels of water consumption to shoot for, before adjusting for exercise. Then, when calculating your specific water-intake needs, you should use the pee test and the pre- and post-workout weigh-ins to get a good idea of how much additional water you should be drinking.
Remember that in addition to drinking water and other fluids, fruits and vegetables are considered hydrating foods. These foods have high levels of water content which help contribute to your daily water needs. Just keep in mind, these foods are great for bolstering basic hydration, but you shouldn't rely on them for post-workout rehydration in place of water, particularly on days when you really push yourself.
A combination of water, food, and if necessary, electrolyte-containing drinks will help you rehydrate post-workout. If it is tough to determine a strict set of fluid intake parameters. But it can be even more challenging to determine if you're drinking enough fluids based on your fitness routine.
By following standard pre-hydration guidelines, and using a combination of the pee test and exercise weigh-ins, you can get a pretty good feel for the amounts of fluid you should be consuming before, during, and after exercise.
Then, based on specific conditions like a very hot day or a particularly strenuous workout , you can make adjustments, as needed.
A high-quality reusable water bottle can help you keep track of your consumption. Here are some additional guidelines on when and how to hydrate. The ACSM's guidelines are fairly general when it comes to drinking fluids before exercise.
They simply state that athletes should start drinking small amounts of water at least 4 hours before a bout of exercise with the goal of reaching "euhydration," or being appropriately hydrated, before exercise begins. This amounts to about 5 to 7 milliliters per kilogram of weight.
If you are dehydrated, you may need another 3 to 5 milliliters per kilogram of weight two hours prior to the event. The recommendation goes as far as suggesting sodium-containing beverages to increase fluid intake and retention.
The ISSN offers slightly more specific recommendations, suggesting that athletes consume milliliters of water or sports drink the night before a competition, milliliters upon waking, and another to milliliters roughly 30 minutes before exercise commences. This, along with a normal eating schedule, should help you achieve optimal pre-exercise hydration.
The problem is that based on activity, duration, intensity, and individual sweat rates and fluid needs, it's nearly impossible to offer a clear guideline. Both organizations note that sweat rates for prolonged exercise can vary from 0.
The ACSM suggests using pre- and post-workout weigh-ins to craft a personalized hydration plan over time based on your own typical fluid losses.
For instance, if you weigh 2. Another starting point recommendation is consuming 0. If you are running smaller bouts, closer to 0. ACSM also recommends consuming 30 to 60 grams of carbohydrates not to exceed 80 grams per hour along with some sodium and potassium. The ISSN, on the other hand, states that athletes should plan to consume roughly 12 to 16 ounces of fluids every 5 to 15 minutes over the course of a workout.
Those performing more intense workouts for longer periods of time, especially in hot or humid environments might consider using an insulated water bottle and should plan on drinking more fluids more frequently, with those performing less intense workouts in less challenging environments skewing toward less fluid consumption on a less frequent schedule.
Post-exercise rehydration comes down to replacing the fluids and electrolytes lost during exercise. This is where the pre- and post-exercise weigh-ins can come in handy. According to the ISSN, for every pound lost during exercise, you should consume 3 cups of water.
This doesn't need to be done all at once. Rather, it can be done steadily following your workout, with the goal of completing consumption before your next bout of exercise to ensure you've appropriately rehydrated. The ACSM notes that if time permits, sticking to a normal eating and drinking schedule after your workout should be enough to restore euhydration.
But if you have to rehydrate quickly say, in between basketball games during a tournament , drinking about 1. Thirst is not a dehydration barometer. This is particularly true during long athletic events, where your fluid loss through sweat may outpace your body's response to flag for thirst.
Water is an excellent drink for rehydration, but you don't just lose water as you sweat—you lose electrolytes, too.
And when you've participated in a particularly sweaty workout, or an extended workout in hot weather, you may end up with an electrolyte imbalance. This imbalance needs to be restored to ensure your body recovers appropriately.
In the following instances listed below, you should consider using fluids with electrolytes mixed in to help rehydrate. 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. Part II: Hydration The month of August brings the commencement of major international competitions and Fall sports practices.

How much fluid should you drink? Before exercise You may need to include fluids that contain sodium before starting exercise. You would want to drink milliliters, or about ounces.
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.

Athletes also need to take care of their regular hydration throughout the day. Preventing dehydration involves more than simply drinking before, during and after exertion. If you're drinking plenty of fluids regularly, your body will be more apt to fight off dehydration during competition. Just scheduling your fluid intake isn't necessarily enough, you should pay close attention to the types of fluid you put into your body. You lose a lot more than fluids when you sweat. When you sweat you lose electrolytes, sodium and vitamins that water doesn't contain. Let's take a look at why these elements are important? Your body requires sodium in order to store and use fluids properly, and simply drinking water just won't cut it. A sports beverage such as TAPOUT can give you the natural sodium your body requires to optimally utilize the fluids you consume. Some athletes may require more sodium than others, so it's important to pay attention to the signs your body is losing sodium from sweat. If your sweat smells or tastes extremely salty, you might be losing sodium more rapidly than you realize. If this is the case, consider consuming an extra TAPOUT Performance beverage rather than water during competition. Under intense activity, your body will burn electrolytes and vitamins. Electrolytes help your muscles remain hydrated and aid in post-competition recovery and vitamins are essential for peak physical and mental performance. When planning your fluid intake for any sport, make sure to include a sports beverage that contains plenty of vitamins and electrolytes. Choosing a sports performance drink that contains carbohydrates is also important. Your body converts carbohydrates into energy, and you may need a boost at practice, games or other forms of competition. Consuming a sports drink containing carbs is a fast and efficient way to refuel your body to give you the energy required to continue at the top of your game. TAPOUT Citrus contains plenty of carbs, natural sodium, electrolytes and vitamins. In fact, at mg TAPOUT contains more natural sodium than any other major sports drink brand. This sodium will aid your body in optimizing fluid usage and help prevent dehydration. Our Citrus flavor also contains 30 grams of carbs to give you the energy needed under pressure. The delicious taste and extra sodium are just two aspects that set TAPOUT apart from the rest. TAPOUT is the only major sports drink to contain all four electrolytes athletes need and a scientifically formulated complement of vitamins. TAPOUT Citrus contains:. While we recommend athletes consider our Citrus flavor for the carbohydrates, those seeking a low-carb, zero-sugar sports beverage can rest assured that our Cherry Lemonade contains all the same sodium, vitamins and electrolytes as our Citrus flavor.
