For most High-performancr events, performance can be limited both by dehydration and by insufficient fuel supplies. If you have the opportunity to use a carbohydrate gel, Unsafe practices in extreme vegan diets is the optimal solution to drink with them as otherwise you'll end up with too concentrated a solution in your stomach 2.
If practicality or gastrointestinal tolerance means eating isn't possible, then using a sports drink such as POWERADE ION4 will help to achieve both fuel and fluid needs at the same time. For those with high sweat rates or particularly long events, it may be necessary to add some extra salt to help ensure good retention and uptake of the fluid into the body 1,3.
If you are considering adding salt to your drinks, consult a sports dietitian first to ascertain the best amount of salt for your specific purposes.
If the weather is hot, try to get access to some cool fluids wherever possible in order to help keep your core body temperature from rising too much. If you are competing in ultra-endurance events, "flavour fatigue" can occur. It can be useful to vary your fluid and food intake to ensure variations in taste so that you maintain a consistent drive to drink and eat.
This is a great time to make use of the delicious varied flavours of POWERADE ION4! Therefore, it might make sense to think that a small amount of dehydration and therefore a lighter weight could benefit performance more than the negative impact the dehydration has on you.
However, when put to the test, this doesn't appear to hold true, especially in warmer climates 4. A similar argument can be made when considering the potential impact on race time of stopping to get a drink at a drink station, even when conditions are milder in temperature. For more information, refer to the section on Hyponatraemia.
Manage training sessions effectively by ensuring adequate fluid intake. Use training sessions to practice drinking and eating strategies for competition.
This includes practicing drinking from a cup when on the move if you're involved in running events, as this is the most common form of delivering fluid at drink stations. Assess your sweat rate during various training sessions different temperatures, distances and intensities so you have a clear plan for required fluid intakes when it comes to a competition.
Aim to drink enough to match your sweat rate as closely as you can in order to minimise dehydration - but avoid drinking more than you sweat. If it's hot, try freezing your drinks overnight so they're still cold by the time you get to drink them.
Do your homework and find out what and where fluids will be available during the competition so that you know what you need to take with you. You may be able to place your own drink bottles out at these stations, or pack a "special needs bag" for yourself to pick up.
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.

Overhydration, known as hyponatremia, is often caused by drinking too much water. The resulting fluid-electrolyte imbalance can cause headaches, confusion, nausea, and fatigue in mild cases or quickly progress to seizures, coma, or even death in severe cases. Because endurance runners have higher fluid needs than the average person, this group is also at higher risk of experiencing hyponatremia through well-intentioned efforts to remain hydrated. With this in mind, it is imperative that runners balance their water intake with sources of electrolytes as well. Keep reading to find out how this can be accomplished. Determining fluid and electrolyte needs as an endurance runner can be challenging because there are a variety of conflicting recommendations. With this in mind, Tables 1, 2, and 3 provide the current evidence-based fluid and electrolyte recommendations for before, during, and after endurance exercise. It is recommended that you use these guidelines as a starting point to create a personalized hydration plan. This will ultimately result in a hydration regimen that allows you to feel and perform your best. Two to four hours before exercise, runners should drink 0. You should be comfortably full when you begin exercise. If you tend to be a heavy sweater or are exercising in a hot climate, your needs may be closer to 0. However, if you are going for a shorter run or do not sweat as much, you can drink closer to 0. You can always adjust the amount you drink before your next run if you find that you need more or less. If you are doing a morning run and do not have time to hydrate 2 to 4 hours before exercise, drink at least 6 to 8 oz of water when you wake up. It is also important that you remain well-hydrated the day before your morning run. Example: A lb individual should drink between Most pre-exercise hydration should come directly from water. If you would like to consume a sports drink with carbohydrates and electrolytes, do so within an hour of exercise. If you are exercising for more than an hour, supplement with electrolytes. Products with both electrolytes and carbohydrates will be most advantageous to performance. You can choose a sports drink, electrolyte powder, gels, or gummies. Salty foods such as pretzels and crackers can be a good option too. If you are a heavy sweater or are exercising in a hot climate, make sure your electrolyte source is rich in sodium. Individuals in this category should consume roughly milligrams of sodium per hour during prolonged exercise. To assess fluid loss, weigh yourself before and after exercise. Any change in weight is reflective of a change in fluid status. For every lb of weight lost, rehydrate with 16 to 24 oz of fluid. If you have gained weight, this is an indicator that you are overhydrating during exercise. Electrolyte replacement after exercise is dependent upon the amount of fluid lost during exercise. If you find that you have to replace a lot of fluid to maintain your pre-exercise weight, add an electrolyte beverage in alongside your water to avoid hyponatremia. Your post-exercise meal can also contribute towards meeting your electrolyte needs. Because sodium is the main electrolyte lost through sweating, prioritize salty foods after exercise. These recommendations apply to all running durations — whether you are completing a short or long run. However, if you are planning to run a shorter distance 3 miles or less and do not want to carry fluids during your run, just make sure that you hydrate before your run and replenish your fluid and electrolyte stores after your run by following the guidelines provided in Tables 1 and 3. While the formal fluid and electrolyte guidelines provide runners with valuable technical information, it can still be difficult to implement and personalize these concepts in practice.

Risks of Fluid-Electrolyte Imbalances Fluid-electrolyte imbalances can be associated with a variety of health conditions, but the two main issues facing runners are dehydration and overhydration. Mild dehydration can be identified by being able to recognize these common symptoms: Thirst Fatigue Dry mouth Dark-colored urine Dizziness Headache Muscle cramping If dehydration progresses to moderate and severe stages, symptoms often escalate to nausea, confusion, and even lethargy. Fluid and Electrolyte Recommendations for Endurance Runners Determining fluid and electrolyte needs as an endurance runner can be challenging because there are a variety of conflicting recommendations. Table 1. Fluid and electrolyte recommendations before exercise Fluid Recommendation Electrolyte Recommendation Two to four hours before exercise, runners should drink 0. Table 2. Fluid and electrolyte recommendations during exercise Fluid Recommendation Electrolyte Recommendation Drink 4 to 6 oz of fluid every 15 minutes throughout exercise. As a good rule of thumb, one big gulp is about 1 oz of fluid. If you are exercising for less than an hour, electrolyte supplementation is not necessary. Table 3. Proper hydration during training or competition will enhance performance, avoid ensuing thermal stress, maintain plasma volume, delay fatigue, and prevent injuries associated with dehydration and sweat loss. It is recommended that athletes drink about mL of fluid solution 1 to 2 h before an event and continue to consume cool or cold drinks in regular intervals to replace fluid loss due to sweat. Maintaining proper hydration before, during, and after training and competition will help reduce fluid loss, maintain performance, lower submaximal exercise heart rate, maintain plasma volume, and reduce heat stress, heat exhaustion, and possibly heat stroke. |

In Dr. Tim Noakes South-Africa-based emeritus professor, prominent sports scientist, and ultra-marathoner published a controversial book titled Waterlogged—The Serious Problem of Overhydration in Endurance Sports.
Noakes was motivated by years spent studying instances of athletes becoming very sick or even dying from the overconsumption of water and diluted sports drinks during competition. Endurance athletes are susceptible to a condition called hyponatremia , which occurs when blood sodium levels become diluted below a critical level.
Once thought to be an extreme scenario, a recent study showed that more athletes suffer complications from hyponatremia each year than from dehydration. He cites anecdotal examples from the early s and into the s, when athletes were actively discouraged from drinking during marathons and other endurance events, yet performed very well.
He also interprets some of the existing research in ways that back up his claims. Overall, Noakes paints a convincing picture that simply drinking water when you feel like it is all you need to perform your best. But taken to the extreme as it often is , it also reminds me of the famous Henry L.
it is more dilute so whenever you produce sweat you lose proportionally more water than sodium. As a result, your blood becomes saltier rather than more dilute as you start to dehydrate.
Those rising blood sodium concentrations are a key part of what drives you to become thirsty. So if you drink water only in response to thirst, you should only ever dilute the blood back down to an acceptable level before the cycle repeats itself.
You should never end up badly diluted hyponatremic unless you drink ahead of thirst which would dilute your blood sodium more than necessary or go for hours and hours drinking only water without replacing any salt. But in general, the idea of drinking solely to thirst seems an acceptable defense against hyponatremia in most cases.
There is, I believe, a huge difference. The environment that we now enjoy in much of the developed world—specifically in terms of our free and ready access to water and salt—is also very different from that of our ancestors.
