Hydration techniques for endurance training -

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.

Clearly, this is not an ideal scenario. Despite these physiologic effects, there is an ongoing debate regarding whether dehydration is that detrimental to sport performance.

Although many studies are consistent with the theory of performance impairment, some recent studies on cyclists did not show an effect on cycling performance. Thus, in conditions where severe dehydration is expected, proper fluid replacement is essential.

They should consume 6mL of water per kg of body mass every hours during the days leading up to competition, including hours before training. To accurately measure daily body mass, the athlete should be weighed first thing in the morning, after completely emptying the bladder and drinking approximately liters of fluid the evening prior.

Sweat rate is highly variable between athletes, with some athletes losing up to 2. Even with these heat adaptations, fluid and electrolyte replacement is needed. Salty sweaters, usually easily identified by having a nice residue of salt on their body and clothes after exercise, need additional supplementation during, and sometimes before, exercise.

During exercise over one hour, athletes should consume 0. If exercising less than one hour, most athletes can get by with replacing fluid losses with water only. High amounts of pure water intake without electrolyte replacement can dilute blood sodium levels and raise the risk of exercise-associated hyponatremia rapid drop in sodium levels in the blood , which can have serious, devastating consequences.
