TrueSport: June 2022 - Hydration

Why and how athletes can have tough talks, when sports drinks should be your go-to recovery drink, are there benefits to enriched water, five sign of dehydration, and easy and health breakfasts, this month from TrueSport.

Athletes: Three times sports drinks should be your go-to recovery drink

As an athlete, sports nutrition and hydration can get incredibly confusing. Are you supposed to be drinking plain water, or sipping a sports drink, or chugging a protein shake? Do you really need electrolytes…and if so, which electrolytes matter most? Unfortunately, the answers to sports nutrition questions tend to be nuanced, and change depending on the style and duration of your practice or game, as well as factors like temperature.

Here, TrueSport Expert Kristen Ziesmer, a registered dietitian and board-certified specialist in sports dietetics, is explaining exactly when sports drinks are the best choice during practices and competitions -- and when they aren’t as helpful.

First, a word on sports drinks in general: When we talk about sports drinks, we’re not talking about caffeine-containing energy drinks, which aren’t healthy for athletes. Sports drinks have carbohydrates and critical electrolytes, including sodium and potassium. If you prefer a homemade approach to sports drinks, check out our simple recipe here.

So, when should you be sipping a sports drink rather than water?

Pre-practice

While you don’t need a sports drink before every practice or game, if you haven’t eaten in a few hours, a few sips of sports drink can help provide the fuel and hydration you need to show up at practice with full energy. “A sports drink is ideal when you need something that will sit light in your stomach while providing quick digesting carbohydrates along with hydration,” says Ziesmer. For students who have early lunch times at school and don’t have the ability to eat an afternoon snack, a sports drink can be incredibly useful.

Hard efforts

If your practice or game day includes a lot of hard efforts, sipping on sports drinks throughout will help keep your energy levels steady while also keeping you hydrated. That means sipping a sports drink between sprints, intervals or breaks in any game like soccer that involves explosive movements. You don’t need to chug an entire bottle of sports drink all at once, though, says Ziesmer. A few sips at a time will be plenty, and drinking too much, too fast can result in an unpleasant sloshing sensation during your next interval.

Long efforts

For long efforts, like a cross-country practice that runs over 45 minutes, sipping a sports drink throughout will help maintain proper electrolyte balance, which will help you potentially avoid things like cramping in addition to fatigue and loss of coordination that come from mild dehydration. The carbohydrate in sports drinks also helps refill your glycogen stores, which rapidly deplete during these longer, more sustained efforts. Again, you don’t want to chug 16 ounces of sports drink in a single drink break: Slow and steady sipping will be more helpful throughout practice.

Hot practices

In extreme heat or humidity, even an easy, short practice can dehydrate athletes. If you’re sweating a lot during practice, that means your body is shedding water and electrolytes, and working harder than it usually does. Electrolytes, including sodium, are expelled as you sweat, and if your body gets out of balance, drinking too much plain water rather than replenishing with an electrolyte-infused sports drink can actually be dangerous. A sports drink is important to help replenish both your electrolyte and water stores, says Ziesmer.

Tournament situations

If you’re in a tournament or competition where there are multiple rounds within a few hours, sipping a sports drink throughout the day may be the best way to continue to ensure that you’re hydrated and that your fuel stores are topped off without making you feel like there’s a lot of food sitting in your stomach. Many athletes also feel nervous or slightly nauseous on days like this, says Ziesmer, so a sports drink can be the ideal alternative to snacking -- though feel free to snack if your gut isn’t bothered by regular foods!

When to skip sports drinks

If your practice isn’t very long or hard, a few sips of regular water during practice and a snack or meal in the hour after practice is all that you need to stay balanced. For hot or long practices, you may prefer to drink plain water and snack on something salty, like pretzels, if you don’t like sports drinks.

Strength training is another time when you likely don’t need a sports drink during the session (unless there’s a cardio component and you’re sweating profusely and boosting your heart rate frequently). You also don’t need to guzzle a sports drink after you’ve already finished your practice. Post-workout, your body needs to rehydrate, but it also needs protein in addition to carbohydrates. You’d be better served by having a chocolate milk, which contains protein, carbs and water. Eating a regular meal within an hour of practice -- along with drinking plenty of water -- is typically going to provide you with the carbohydrates, protein and electrolytes that your body needs to boost its recovery process.

Takeaway

Anytime you’re putting in a higher-than-normal effort (in terms of time or intensity), or you’re sweating a lot, a sports drink is the best way to replenish critical electrolyte stores and rehydrate you, while providing a small amount of fuel to help you better absorb the water and boost workout performance. And remember: Your health is important, so don’t be afraid to ask for time to rehydrate during practices or games!

Parents: Are there benefits to using enriched water?

Alkaline water, mineral water, carbonated water, coconut water: There are so many different water options available that it can feel a bit overwhelming at the grocery store. Which one will serve your athlete best, or is plain old tap water the optimal solution?

Here, TrueSport Expert Stephanie Miezin, MS, RD, CSSD, explains the difference between different types of enriched waters -- including the role of sports drinks -- and discusses how you can determine the best option for your athlete.

Sports drink versus enriched water

In general, when we talk about water, we’re talking about water with minimal (if any) calories added. Electrolytes may be included. Sports drinks usually refer to caloric beverages that contain not only critical carbohydrates, but electrolytes like sodium and potassium as well. These electrolytes are crucial to rehydration: Especially in hot, humid weather or after extreme exertion, water alone may not be enough to adequately rehydrate your athlete.

Label confusion

Some waters may sound sport-ready: alkaline water and mineral water both seem like they’d contain vital electrolytes to help your athlete excel on the playing field. But neither beverage contains more than trace minerals, and will work only as well as regular water, just with a higher price tag.

“Alkaline water is just a marketing ploy,” says Miezin. “Our bodies are perfectly capable of staying at the proper pH without help from alkaline water -- we have natural mechanisms for that, and if you were to get out of balance, you’d probably be in the hospital.”

On the other side of the spectrum, coconut water may sound like simple flavored water, but it actually contains carbohydrates and some electrolytes.

Avoid energy drinks

Above all, Miezin discourages parents from buying any ‘energy drinks’ for young athletes. Energy drinks are designed for adults, and that level of caffeine may not be healthy for teens or children. Energy drinks often are very high in sugars and stimulants that make these drinks generally not a good option for young athletes. Additionally, excess caffeine found in many energy drinks may be dehydrating, potentially exacerbating the effects of heat and humidity.

Plain water works well when snacking

Remember, carbohydrates and electrolytes can also be delivered via whole foods. “A handful of pretzels adds carbohydrates and a good dose of sodium, so that’s great with plain water,” says Miezin. If your athlete is going to be snacking before or during practice, plain water is just fine.

What to look for:

An ideal sports drink for both rehydration and carbohydrate energy should have 14-19 grams of carbs, 110-166 mg sodium and 19-47 mg potassium per 8-ounce serving, says Miezin. However, carbohydrates aren’t always required. If an athlete is playing for under an hour, they likely don’t need the added sugars to perform, and water, or water with electrolytes or a pinch of sea salt, could do the trick to support hydration needs.

When buying water or sports drinks, check the labels carefully. Some electrolyte tabs, for example, are meant to be used in a 16-fluid ounce water bottle, while some show serving sizes for 8 ounces.

For the homemade sports drink, try this simple recipe that yields five servings (8 ounces each):

  • 4-1/4 cups water
  • 1/2 cup 100% orange or other fruit juice
  • 4-1/2 tbs. granulated sugar
  • 1/2 tsp. kosher/sea salt

Mix together until salt and sugar are totally dissolved. Keep cold until ready to drink. Will stay fresh for up to 5-7 days in the fridge.

Takeaway

Make sure that your athlete is taking in some form of water, electrolytes (especially sodium), and carbohydrates before and during sports practice, especially for practices over an hour. Check labels carefully, since some products may sound more compelling than they are in reality.

Coaches: Five signs of dehydration and how to best rehydrate

-- Hot weather is coming, and that means your athletes are at a higher risk of becoming dehydrated during practices and games. And even mild dehydration can impact athletic performance as well as an athlete’s general health. Losing just 2 percent of an athlete’s bodyweight through sweat loss can change how an athlete is feeling and performing, whether they are sprinting at a track meet or participating in a day-long volleyball tournament.

Here, TrueSport Expert Stephanie Miezin, MS, RD, CSSD, is sharing what you need to know to help athletes stay safe on the field.

Signs of dehydration

1. Don’t count on the scale

As we mentioned, a loss of two percent of an athlete’s bodyweight due to sweat loss is a strong signal for dehydration. But in reality, that calculation is pretty complicated. Miezin explains that you would need to weigh an athlete immediately prior to practice -- accounting for clothing -- then account for all fluid lost through using the bathroom as well as all fluid gained from sipping water or a sports drink, or even including food eaten. “It’s usually impractical for athletes, and for coaches,” she adds. You need a smart scale, a food scale and a degree in mathematics to keep track of that 2 percent loss! That’s why most research that cites the two percent statistic is done in controlled lab conditions. So, in real life, how do you know if an athlete is becoming dehydrated?

2. Pay attention to subtle cues

Rising irritation levels, increased fatigue, dizziness and trouble paying attention are all early warning signs that an athlete may be becoming dehydrated, says Miezin. The biggest sign is a drop in energy levels, which can sometimes be attributed to calorie deficiency rather than dehydration. The two are not mutually exclusive, of course, so if you’re noticing any of these signs in an athlete, stopping for a sports drink or water plus a snack break is a smart idea.

3. Look for physical indicators

Loss of coordination, nausea and cramping are all indicators of dehydration, though they all have other causes as well. An athlete who seems to be losing coordination may be in the early stages of dehydration or even heat exhaustion, says Miezin. Unfortunately, loss of coordination and nausea can also both be brought on by a concussion, so it’s important to make sure that an athlete didn’t suffer from a hit to the head. Cramping may be another indicator of dehydration, though it’s not a guarantee. “We still don’t know exactly what causes cramping for athletes,” she says. “But because it may be caused by a fluid and electrolyte imbalance, making sure that an athlete who is cramping is rehydrating properly may be helpful.”

4. Early dehydration doesn’t have obvious physical manifestations

“I remember having a coach who would take me out of games almost immediately when it was hot out, because my face would get very red, very easily,” Miezin recalls. A red face isn’t an indicator of dehydration or even heat exhaustion, though. Some people are just naturally more prone to flushing in higher temperatures. Some athletes are also heavier sweaters than others, and while it might look worrisome, it’s perfectly natural. For the heavier sweaters, do prioritize sports drinks or water with added electrolytes, as those athletes are losing more electrolytes and fluids at a higher rate than less sweaty athletes.

5. Educate your athletes

One of the common indicators of dehydration is urine color. Typically, the rule is that urine color should ideally look like ‘lemonade.’ “Apple juice color or darker can be a sign of dehydration,” Miezin says, but cautions that other factors can influence urine color. An athlete eating beets or taking certain vitamins or supplements may end up with brightly colored red or yellow urine, which can mask dehydration issues. Despite those variables, you can tell athletes to pay attention to urine color -- and how often they need to pee -- as potential warning signs for dehydration.

How to rehydrate

1. Dehydration can happen even in short practices

If practices or games run over an hour, make sure you’re allowing athletes time for an electrolyte-infused water and/or snack break. If a session is particularly intense, especially in hot weather, you may need to break more often. While most short practices don’t require an athlete to take in extra water or calories, if the athlete is starting practice mildly dehydrated, even a 45-minute session can dehydrate them. As temperatures rise, recommend that athletes show up to practice with sports drink or water that has electrolytes or a pinch of sea salt added. And never disallow an athlete from taking a break to hit the water fountain if they ask!

2. Rehydrate with electrolytes and water

You may be surprised to learn that dehydration isn’t just water depletion. Your athlete needs to replenish critical electrolytes along with water in order to better absorb the water quickly. That means sports drinks are the best option for rehydration, rather than plain tap water, says Miezin. Adding a pinch of sea salt to regular water is another option, as is eating a salty snack while drinking water, especially if you don’t have access to a sports drink and you believe that an athlete is beginning to show signs of dehydration.

3. Don’t gulp gallons of water

When rehydrating an athlete, try to focus on slow and steady sipping. Sipping allows for better absorption of water rather than chugging. Drinking too much, too fast can have other potentially harmful effects other than needing to take more bathroom breaks. “It’s generally not ideal to encourage athletes to start chugging plain water,” says Miezin. “Water without electrolytes can lead to hyponatremia when consumed in large quantities, which is when the body’s sodium levels become dangerously low.” Unfortunately, hyponatremia can be deadly for young athletes, which makes following rehydration procedures even more critical. Water alone won’t rehydrate your athlete: A balance of electrolytes and water is necessary.

4. Take a break

If you suspect an athlete is becoming dangerously dehydrated -- their mood or coordination is affected -- t’s time for a break. That may mean a short break on the sidelines as they slowly sip a sports drink, or it may mean sitting out the rest of the game altogether, depending on how well they seem to bounce back. You’ll have to make a judgment call on whether they should return to play, says Miezin. (Remember, it’s always better to err on the side of caution.) Additionally, make sure that the athlete is out of the sun and sitting or lying down to recover. Dehydration in hot, humid weather can cause an athlete to stop sweating, which can eventually lead to heat exhaustion or heat stroke, so cooling them down is also important.

5. Dehydration is a year-round issue

In the summer, athletes are more likely to become dehydrated due to heat and humidity, but it can happen anytime during the year. Indoor practices are often pretty warm and busy lifestyles can lead to dehydration even on mild days. So, keep an eye out for these symptoms all the time, not just when summer hits.

Takeaway

Dehydration symptoms are hard to see, so pay close attention for signs like a loss of coordination, increased irritability, and fading energy. If you suspect an athlete is becoming dehydrated, ensure that they pause and sip a sports drink (ideally chilled), as well as allow their bodies to cool down.

Nutrition: Three easy and healthy breakfasts for athletes

For young athletes, breakfast is an important meal, but it’s also the most likely to get skipped in order to finish that homework assignment or catch the bus. And as a busy parent, you may simply find yourself struggling to make a healthy breakfast for your athlete as you rush to get out the door to head to work on time. But there are plenty of easy, healthy options that can be prepped ahead of time and only take a few minutes to whip up.

Here, TrueSport Expert Kristen Ziesmer, a registered dietitian and board-certified specialist in sports dietetics, shares a few favorites. But first, she’ll talk about the contents of a good breakfast.

What’s in a good breakfast?

A healthy breakfast for a young athlete needs to contain the major macronutrients: protein, fat and carbohydrates. Including all three will ensure that your athlete is full and satisfied until lunch. That’s why, for instance, our egg recipes all include toast or potatoes to provide the much-needed carbohydrate element. Skip that, and your athlete will be low on energy. Portion size also matters. A single egg and slice of toast will provide less than 200 calories and only seven or eight grams of protein, compared to an egg and cheese sandwich on whole grain bread made with two eggs and two slices of bread, which would provide around 20 grams (a full serving) of protein in addition to healthy fats and complex carbohydrates for a meal of around 500 calories.

With this in mind, here are a few recipes that can also be made in minutes or prepped at the beginning of the week to make mornings simple:

Overnight oats

Make: The night before

1 serving

Notes: If you prefer to meal-prep early in the week, mix together individual mason jars of the dry ingredients. Add the wet ingredients the night before, though, otherwise by the end of the week, the oatmeal will be too mushy to be appetizing. This is a great meal prep activity to do with your athletes, and ideal for parents with multiple picky eaters since each can choose their own toppings and flavors!

  • 1/2 to 3/4 cup rolled oats
  • 1/2 to 3/4 cup milk (Whole milk provides a great protein source, but plant-based alternatives are fine. Look for protein-enriched options.)
  • 1/2 teaspoon vanilla extract
  • Optional sprinkle of cinnamon or cocoa powder
  • 1-2 tablespoons maple syrup or honey
  • Choose your own fruit toppings: mixed fresh berries, sliced bananas, frozen berries, chopped apple
  • Choose your own added fat/protein: chopped nuts, hemp seeds, chia seeds, nut butter, shredded coconut

Mix all ingredients together in a mason jar or other single-serve container.

Store in the refrigerator overnight.

In the morning, your athlete can eat this cold, or it can be microwaved if preferred.

Vegetable frittata

Make: At the start of the week

4 to 6 servings

Notes: Vegetable frittatas are great options for athletes who prefer savory breakfasts, since they can be made ahead of time and will stay tasty in the fridge for a few days. Be aware of portion size: You may assume since this cooks in a pie pan, it will serve eight. But athletes on the go will want more than 1/8 of the pie to stay satisfied. For smaller/younger athletes, a 1/6 serving of the pie should be plenty, but older athletes should eat 1/4 of the pie to ensure they get enough protein and carbohydrate from the potatoes and eggs.

  • 10 eggs
  • 1/3 cup whole milk
  • Frozen shredded hash brown potatoes
  • Your choice of vegetables: Frozen or fresh vegetables of any type work in this! Choose your athlete’s favorites, and if you don’t have time to chop veggies, look in the frozen aisle for pre-chopped mixes that would work well with eggs. Chopped spinach, onions, peppers and broccoli are common favorites.
  • Optional: cheese, bacon bits, salt, pepper, hot sauce

Preheat oven to 375 degrees.

Defrost frozen vegetables and hash browns.

Spray or rub deep 10-12” pie pan or cast iron skillet with oil.

Use hash browns to create a crust in the bottom of the pie pan (breaking up patties if needed). This doesn’t need to look like a perfect pie crust, as the egg will bind it all together in the pan.

Bake hash browns for 5-10 minutes until they become slightly crispy.

In a bowl, whisk eggs and milk together.

Optional: Sauté your vegetables with olive oil, salt, and pepper.

Mix vegetables into egg mixture.

Optional: Add cheese, salt, pepper, and a drizzle of hot sauce if desired.

Pour egg mixture into your pie pan.

Bake for 15-20 minutes or until fork comes out of eggs cleanly.

Chia seed pudding

Make: At the start of the week

5 servings

Notes: Chia seed pudding is a great option for an athlete who loves tapioca pudding or needs something easy to eat on the go. It’s nutrient dense for a relatively small volume of food, so it’s a great solution for an athlete who just isn’t into eating in the morning. Chia seed pudding is a great source of protein and healthy fats, but on its own, it’s low in carbohydrates. Make sure that you’re adding plenty of fresh, frozen or dried fruit to the pudding in addition to a sweetener like maple syrup or honey to make it more satisfying.

● 1 cup chia seeds

● 4.5 cups milk (Whole milk provides a great protein source, but plant-based alternatives are fine. Look for protein-enriched options.)

● 1/2 teaspoon vanilla extract

● Optional sprinkle of cinnamon or cocoa powder

● 1-2 tablespoons maple syrup or honey

● Choose your own fruit toppings: mixed fresh berries, sliced bananas, frozen berries, chopped apple, dried fruit

Mix all ingredients together in a large storage container, or pre-portion into five smaller containers. If your athlete likes to mix things up during the week, make the base separate (chia, milk, vanilla and sweetener) and add toppings separately each morning.

Store in the refrigerator overnight; it will stay good for a full week.

On-the-go-options

No time? No problem. Just remember to include protein, carbohydrate, and fat, ideally with some fiber and micronutrients from fruits or vegetables.

● Nut butter and jam on whole wheat bread (look for a multi-grain option that includes nuts and seeds for extra satiety)

● Plain 2% Greek yogurt with honey and berries

● Two hardboiled eggs or 2-3 slices of cheese with a whole grain bagel and some mixed berries

Takeaway

Breakfast is critically important for young athletes, but often, athletes in a rush skip or skimp on breakfast, which could lead to inadequate nutrient intake and/or poor performance at practice or games. But breakfast doesn’t have to be a gourmet affair: There are simple recipes that make it easy to provide plenty of protein, fat and carbohydrates to your active student.
