Are there instances when sports activities drinks with electrolytes are obligatory for hydration?
Vitamin Diva listener Phillip writes: “I work exhausting outdoors day-after-day and I sweat lots. I drink 2 to three liters of Gatorade Zero for the electrolytes. I select the artificially-sweetened drinks to keep away from consuming an excessive amount of sugar, however are the unreal sweeteners or different components in these drinks dangerous for me?”
Phillip brings up a number of attention-grabbing questions: When is it obligatory to interchange the electrolytes we lose once we perspire? Is a sports activities drink like Gatorade one of the best ways to do that? And what concerning the sugar or synthetic sweeteners in these drinks? Are they dangerous?
To assist me type by way of all of this, I sat down with sports activities nutritionist Kelly Pritchett. Dr. Pritchett is an Affiliate Professor in Vitamin and Train Science at Central Washington College. She’s labored with elite and collegiate athletes in addition to with energetic people, and he or she’s an athlete herself. In right this moment’s present, I will share a number of the insights and knowledge that I gleaned from my conversion with Kelly.
What occurs while you sweat?
Let’s bracket, for a second, the query about sugar vs. synthetic sweeteners and discuss first about what occurs once we sweat. In accordance with Dr. Pritchett, your physique may produce anyplace from half a liter to three liters of perspiration per hour. How a lot you sweat will rely in your stage of exertion and the circumstances—how sizzling or humid it’s, or each. But it surely’ll additionally rely in your stage of health, and the way accustomed you might be to the environmental circumstances.
Relying on how lengthy and exhausting you are sweating, the lack of fluids might trigger you to develop into dehydrated. And this may be remedied just by taking in plain water.
You are not solely shedding water while you sweat. You are additionally shedding electrolytes: sodium, magnesium calcium, potassium, and chloride.
However, after all, you are not solely shedding water while you sweat. You are additionally shedding electrolytes: sodium, magnesium calcium, potassium, and chloride. Dr. Pritchett factors out that you just lose much more sodium than the rest. Common sodium losses are 1,000 mg per hour! That is nearly a one-half teaspoon of desk salt.
Extreme and prolonged sweating can probably result in dangerously low blood sodium ranges, a critical situation known as hyponatremia. In these conditions, consuming an excessive amount of plain water, with none electrolytes, can truly make the scenario worse by additional diluting the sodium focus of the blood.
For those who’re taking part in a set of tennis, operating a 5K, or out within the backyard for a few hours, and also you’re in any other case wholesome, you are in all probability nice consuming plain water. But when you’re going to be sweating exhausting for greater than 60-90 minutes, Pritchett says it is a good suggestion to consider changing these electrolytes as properly.
The best way to change electrolytes
One simple approach to change electrolytes is to easily eat one thing salty—some salted nuts or sunflower seeds, for instance. So, in Phillip’s case, he may select to take a break each couple of hours and have a fast snack or a meal, together with loads of water. A salty snack will rapidly change the sodium he might have misplaced in addition to smaller quantities of different minerals.
For athletes engaged in endurance sports activities, nonetheless, consuming is probably not possible. That is the place sports activities drinks may appear to make sense. These sports activities drinks might help change the fluids you lose, however they might not present sufficient sodium to maintain up with losses utterly.
One simple approach to change electrolytes is to easily eat one thing salty—some salted nuts or sunflower seeds, for instance.
Common Gatorade, for instance, incorporates about 450 mg of sodium per liter. For those who’re shedding 1000 mg of sodium per hour, you’d must drink half a gallon of Gatorade each hour to maintain up. Powerade, one other standard model, is even decrease, with solely 225 mg of sodium per liter.
Dr. Pritchett notes that there are some sports activities drinks (in addition to gels and gums) which can be specifically formulated for endurance athletes and have the next focus of sodium. You too can add a pinch of sea salt to your water bottle or your sports activities drink, she says, to extend the sodium content material. And at last, there are salt and electrolyte alternative tablets that athletes usually use to compensate for losses.
How a lot sodium do you have to absorb throughout train?
In accordance with Pritchett, the quantity of salt you lose in an hour of train is lots lower than the everyday American consumes every day. It in all probability would not must be changed.
However for those who’re working in sizzling circumstances for hour after hour, or engaged in intense and prolonged train, how a lot sodium per hour do you have to absorb? Pritchett says this will range considerably from particular person to particular person.
One liter of fluid and 1,000 mg of sodium per hour of prolonged heavy sweating is an efficient rule of thumb.
“I’ve athletes who’re very salty sweaters,” she defined. “You possibly can truly see a whitish movie on their pores and skin after train.” So it is not going to be a one-size-fits-all prescription. However, one liter of fluid and 1,000 mg of sodium per hour of prolonged heavy sweating is an efficient rule of thumb.
That sodium can come from meals, sports activities drinks, salt tablets, sports activities gels, salted water, or any mixture of these issues. (Examine the vitamin details label on any product you select to see how a lot sodium they include.) Keep in mind that your post-workout meal can even go an extended approach to replenishing these electrolytes.
Are sports activities drinks with synthetic sweeteners higher?
Lastly, let’s return to Phillip’s query about sugar vs. synthetic sweeteners in sports activities drinks.
Earlier than they grew to become a preferred class of soppy drinks, sports activities drinks have been designed to assist athletes engaged in prolonged, strenuous train. Endurance athletes who train lengthy and exhausting sufficient to exhaust their muscle shops of glycogen usually depend on sugar-sweetened drinks, gels, or goos as a fast supply of prepared power that may be consumed throughout a exercise.
Your muscular tissues typically can retailer sufficient power to energy you thru about 2 hours of nonstop, high-intensity train.
You do not want a shot of sugar to get you thru a 60-minute Zumba class, by the best way. Your muscular tissues typically can retailer sufficient power to energy you thru about 2 hours of nonstop, high-intensity train. Past that, you may in all probability have to devour some type of energy to maintain your efficiency from flagging. And clearly, a sugar-free sports activities drink goes to be fairly ineffective as a supply of power.
Outdoors of endurance train, sports activities drinks are merely one other supply of added sugars. I respect Phillip’s concern about minimizing his consumption of added sugars, however I am not an enormous fan of consuming artificially-sweeteners drinks all through the day. Although they might help folks scale back energy and sugar, there are a lot of different issues. Numerous research have appeared on the results of noncaloric sweeteners on issues like insulin ranges, urge for food regulation, and blood sugar metabolism. Thus far, the evaluations have been blended, with some research discovering hostile results and others discovering no impact.
There are additionally issues concerning the impact of synthetic sweeteners on intestinal micro organism. Artificially-sweetened meals and drinks typically do not supply a lot in the best way of vitamin. For all of those causes, I normally advocate consuming artificially sweetened meals the identical diploma of moderation that you just’d use for sugar-sweetened meals and drinks. And a number of other liters a day is certainly greater than I might take into account reasonable.

The underside line on sports activities drinks with electrolytes
For those who’re exercising for lower than 90 minutes, you in all probability need not fear about changing electrolytes as you go. You additionally don’t want extra sugar or carbohydrate to gas your muscular tissues. You possibly can drink water to interchange the fluids, and you can change the electrolytes at your subsequent meal.
For those who’re exercising for lower than 90 minutes, you in all probability need not fear about changing electrolytes as you go.
Endurance athletes might lose 2-Three liters of sweat per hour for a number of hours in a row. A sports activities drink might help replenish fluids and likewise provide a supply of carbohydrate gas for muscular tissues. Nevertheless, a sports activities drink might not include sufficient sodium to interchange losses.
Now, let’s take into account those that work outside—everybody from navy personnel to landscapers to building staff to bicycle messengers to tour guides. Your stage of exertion is probably not fairly as intense or sustained as an endurance athlete’s. Even so, circumstances might be excessive, and it’s possible you’ll be outside for hours on finish. Drink loads of fluids to remain hydrated. For those who’re not capable of eat at common intervals, it’s possible you’ll want to complement with an extra supply of salt. A salt pill or a pinch of salt in your water might be useful.
In case your sport or line of labor signifies that you spend many hours a day sweating, it’s possible you’ll wish to seek the advice of with a dietitian or sports activities nutritionist. It is a good suggestion to evaluate your sweat charge and composition and get a person prescription for fluid and electrolyte alternative.
