Your Guide to Using Electrolytes Properly

Given how usually we see the phrase “electrolyte” listed on sports activities diet merchandise, you’d assume we’d know just a little extra about them. Instead, many people drink, chew, and slurp down expensive merchandise that declare to revive electrolytes and forestall fatigue with out giving the ingredient listing one other thought.

The fact isn’t fairly that easy. Here’s all the pieces it’s essential learn about electrolytes—and how you can greatest tailor the merchandise that include them to your physique’s wants.


What Are Electrolytes?

“Electrolytes are the medium through which electricity gets transferred throughout the body,” says Stavros Kavouras, director of the Hydration Science Lab at University of Arkansas. These salts enter our our bodies by way of meals or drink, then flip into the fees that spark cell operate, making them accountable for nearly all the pieces. They play a task in muscle contraction, metabolism, and numerous different cell capabilities, says Robert W. Kenefick, a physiologist with the U.S. Army Research Institute of Environmental Medicine who makes a speciality of hydration. Without electrolytes, our cells would have bother self-regulating, which might throw lots of our fundamental bodily capabilities completely out of sync. According to Kenefick, after we discuss what we could lose by way of sweat—keep in mind, electrolytes are salts, in any case—we’re referring to sodium, chloride, and potassium, and small quantities of calcium and magnesium.

What Causes an Electrolyte Imbalance?

“For the most part, if you have a normal diet, particularly a diet in the U.S., you’re probably getting all the electrolytes you need on a daily basis,” Kenefick says. Electrolytes are misplaced naturally by way of urination and sweat after which changed by way of meals.

Sweat truly accommodates a comparatively low focus of electrolytes, which varies extensively based mostly on the person. “From person to person, the difference in electrolytes lost through sweat can vary by as much as two to three times,” Kavouras says. Some individuals are genetically heavy sweaters, whereas others are low sweaters. Some are referred to as salty sweaters, which means they’ve very excessive sodium concentrations of their sweat. (You know you’re a salty sweater should you get white streaks or rings in your clothes while you work out, Kavouras says.) Some individuals are a heavy and salty sweater combo, which suggests they need to pay nearer consideration to the quantity of electrolytes they absorb. But for the typical athlete, the size and depth of train are the largest elements that decide when it’s essential complement.

When Should You Reach for Electrolytes?

“Unless you exercise for more than three hours, you don’t need to add electrolytes,” Kavouras says. “No one has complications related to electrolyte imbalance for anything, assuming you start your exercise in a balanced state.”

Anything longer than that, although, and also you’re in danger for depletion. “Individuals who are doing work where they would be sweating profusely for a number of hours, particularly day after day, need to take electrolytes into account,” Kenefick says. That contains endurance athletes, some navy personnel, sure guide occupations, and sports activities that happen within the warmth and require a number of practices a day.

That stated, longer doesn’t all the time translate to needing extra of the salty stuff. Say you go on a delicate six-hour hike on a light autumn morning. You in all probability aren’t sweating very a lot and, due to this fact, probably don’t want further electrolytes. But should you’re doing a 50-mile bike experience at excessive midday in August, which might be a shorter length, you’d be clever to stash some electrolyte merchandise in your singlet.

How Do Electrolytes Help?

Chances are you’ve skilled extreme muscle cramps sooner or later in your life. You probably assumed the cramps occurred since you had been low on electrolytes. But science hasn’t been capable of again that up regardless of the function of electrolytes in muscle contraction, Kenefick says. In a study of Ironman triathletes, touring at quicker speeds was truly extra more likely to be a predictor of cramping than dehydration or decreased electrolyte ranges. “You’d be extra inclined to be fatigued since you’re working low on glucose—which feeds vitality into your muscle tissue—than due to an electrolyte imbalance,” Kenefick says.

It’s nonetheless doable that electrolytes, notably sodium, can support efficiency. When researchers had 1 group of athletes eat salt capsules along with sports activities drinks throughout a 1/2 Ironman and had a management group eat solely sports activities drinks, the group supplementing with sodium accomplished the race a mean of 26 minutes quicker, in response to a examine within the Scandinavian Journal of Medicine and Science in Sports. The group consuming simply the sports activities drinks changed round 20 % of the sodium they misplaced throughout the race, whereas the group including salt tabs changed round 71 % of the sodium they misplaced by way of sweat. Sodium helps your coronary heart by protecting the blood vessels round it crammed with the correct amount of water. That permits it to keep up blood circulation to the muscle tissue in want throughout effort, which might have a useful impact on efficiency, Kavouras says.

Where Should Your Electrolytes Come From?

The fact is that the parameters surrounding correct electrolyte consumption stay imprecise and largely undeveloped. As far as scientists know, there’s no single technique that’s greatest. Sports drinks win on comfort, Kavouras says. You get hydration, carbohydrates, and electrolytes multi function easy-to-consume bottle.

Unless you’re in the midst of an intense endurance effort—like, say, a marathon—you may get what you want with none supplementing. “I recommend people eat real food, because some manufactured foods are super-concentrated,” Kenefick says. “When you’re taking in this bolus of salt and glucose, it can sit in your stomach and exacerbate GI distress.”

“Just don’t do what I once saw someone doing at an ultra—dumping half a salt shaker in his mouth at a checkpoint,” Kavouras says. “You don’t need that much!”
