Many coaches and athletes have come to support a theory that drinking only water, only when you feel enduranxe, is enough of a hydration strategy to keep you performing Hdration your best during Hydration and endurance events.
Anv prevailing Hydartion Turmeric for joint pain touts the Hydation of Hyrration replacing the electrolytes lost in our enduranxe. Well, it depends…. In Endurznce. Tim Noakes South-Africa-based Hyvration professor, prominent sports scientist, Turmeric for joint pain ultra-marathoner published a controversial book titled Waterlogged—The Hydratiob Problem of Overhydration in Endurance Sports.
Noakes was motivated by years spent studying instances of athletes becoming very sick or even dying from Hydration and endurance overconsumption of water and enduranec sports Hydratioh during competition. Endurance athletes are susceptible to a condition called hyponatremiawhich occurs when blood sodium levels Hydgation diluted below a Hycration level.
Once thought andd be an extreme scenario, eendurance recent study showed that more endirance suffer Cancer prevention for women from endurancr each year than from dehydration. He cites Hyxration examples from the early s and into endurznce s, when athletes Visceral fat and cardiovascular health actively discouraged from drinking during marathons and other endurance events, yet performed Hydeation well.
He also interprets some of endutance existing research in ways that Hydrationn up his claims. Overall, Science-backed metabolism support paints Hyeration convincing picture that simply Hydratuon water when enndurance feel like Hyddation is all you need Hydration and endurance perform enurance best.
But taken to the extreme as it often endursnceit fndurance reminds Hydratoin of the famous Henry L. Hydration and endurance 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 Hydrztion dilute the blood back down to an acceptable level before the cycle repeats itself, Turmeric for joint pain.
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. And even if you are perfectly aware of your thirst signals as a general rule, the elite athletes we work with are very in touch with their bodiesthe demanding and complex nature of competition Hyxration make it difficult to find physically and tactically ideal moments to hydrate.
Drinking water to thirst is very likely sufficient for short and Hydrxtion activities where sweat losses are low to moderate, but the data is a lot less clear for longer and hotter eventswhere sweat loss can be considerable over many hours.
It was even copied by many of his competitors, presumably because it worked. More recent research showed that endurabce who were given salt tablets vs. a placebo during a middle distance race were ~26 min Hyvration on average.
The study also showed that the group taking salts rehydrated more effectively than the control group. This certainly tallies with my own experiences using sodium supplements during long, hot races.
Sports drinks are arguably overused by a lot of people, but they have been proven time and time again to provide performance-enhancing benefits to athletes and humans in general in the right scenarios. There are lots of scenarios where just drinking water to thirst is sensible, like for basic day-to-day hydration.
And for many people training or racing shorter events in cool to moderate conditions, drinking water to thirst will be sufficient most of the time. There may be some benefit to having a basic hydration plan to follow, or in taking steps to ensure you start properly hydrated. Your plan should be individualized and flexible enough to be tweaked on the go.
It should also utilize biofeedback including a big reliance on your sense of thirst to determine how much fluid and sodium you take in. Taking this free online Sweat Test can help you get started.

Proper Hydration Is Key for Endurance Athletes Wednesday, August 01, PM Tags: endurance training , hydration , water. Brian Shortal, MD, Cardiologist at NorthShore, marathoner and triathlete, gives his advice on what endurance athletes can do to stay properly hydrated: Drink plenty of water before, during and after a workout. Remember: A loss of two pounds is the equivalent of one liter of fluid. Replenish your electrolytes. When you sweat, your body loses sodium, calcium, potassium and other important minerals. Though it may seem counter-intuitive, adding water without electrolytes may make this situation worse. In actuality, that myth can be quite harmful—and even more-so than dehydration. Drinking water without replacing lost sodium dilutes blood sodium levels , and can cause a dangerous condition called hyponatremia. The headaches, cramps, and confusion that come with exercise-associated hyponatremia plague a large portion of athletes. To make matters worse, exercise-associated hyponatremia is often confused with dehydration. This results in a dangerous and ineffective prescription: Drink more water. Endurance athletes need to drink more water than most folks to replace the fluids lost through their sweat. But for the sake of their health, that water NEEDS to contain sodium. There are two factors at play here: 1 water, to provide the fluid volume to minimize stress on the cardiorespiratory system, improve evaporative cooling, etc. This will set the stage for later, when we get into hydrating for endurance sports. Hydration is a state of fluid balance in your body, not the act of pounding fluids. A state of euhydration is essential for good health. Normally, your body does a nice job maintaining euhydration. Electrolytes are essential too— especially sodium. Sodium is a positively charged mineral called a cation responsible for regulating extracellular fluid balance, or the water outside of your cells. This suboptimal hydration takes two forms:. I want to cover each separately, because both states can sap your energy, performance, and recovery. Long-distance and high-intensity activities like running, cycling, and obstacle racing provoke tremendous sweat loss. As a result, total body water decreases significantly. While this is certainly an interesting thought, a few things are still not clear. For starters, how do these folks manage to use this technique without disrupting electrolyte balance? And is part of the reason that these athletes manage to compete at such a high level due to their ability to function at a modestly dehydrated state? At a minimum, we can argue the case that truly elite athletes are not necessarily avoiding dehydration at all costs. Dehydration , in case you were wondering, is the process of losing those fluids. Hypohydration is the result. When someone is hypohydrated, exercise tolerance decreases and performance suffers. This is well-documented , but the mechanisms behind why this happens are up for debate. One potential reason? Skin temperature increases, and your ability to sweat and, therefore, cool down decreases. This is also why, at any given temperature, higher humidity makes exercise harder and more physically stressful. Even whilst well hydrated, high humidity reduces the effectiveness of evaporative cooling via sweat. To reinforce that last point, in one study , researchers found that when cyclists were hypohydrated, performance declined in lock step with rising skin temperature. Should you just drink more water, then? Since sodium regulates fluid balance, adequate sodium intake is required to retain water and maintain the electrochemical gradient produced by higher concentrations of sodium outside cells and higher concentrations of potassium inside cells. A consensus statement from the International Olympic Committee reads:. To prevent dehydration, many athletes guzzle sodium-free water beyond what thirst prompts. To make matters worse, guzzling water creates a bigger problem: Hyperhydration. Hyperhydration, also known as overwatering or water intoxication, is a potentially fatal state of electrolyte disturbance brought on by excessive water consumption. You see this a lot in marathons. Runners drink electrolyte-free water on a set schedule, dilute blood sodium levels, then suffer the consequences of exercise-associated hyponatremia low serum sodium. Hyponatremia is serious stuff. In the beginning, it causes headaches, cramps, confusion, and fatigue. As sodium levels continue to fall, seizures, brain damage, and even death can result. More than a few elite athletes have perished from hyponatremia. What about dehydration? Not one sports-related death, in all the medical literature. Fortunately, exercise-associated hyponatremia is fairly easy to prevent and reverse. Sodium is an electrolyte that helps you transmit nerve impulses, regulate blood pressure, and maintain body water. And when sodium levels fall to hyponatremic levels, the consequences are no joke. Sodium needs go up in proportion to sweat loss. And the volume of sweat loss depends on the activity, ambient temperature, humidity, and a few other factors. |
