Why Carbs Can be a Dancer’s Best Friend

Want better jump height, more endurance, improved brain function and better fat burning? Then carbohydrates can be your best friend.

Should I eat a high protein, low carb diet?

There always seems to be yet another new bestselling, yet unscientific diet trend that touts low carb, high protein eating. These diets are not good for anyone, but this is especially so for the type of activity that dancers do. Certainly adequate protein is important, but the body would prefer to spare it for important physiologic functions, not burn it as fuel. Carbs provide the type of fuel that the muscles need for dance. High protein diets can lead to lower bone mineral density and increased risk for long-term diseases. Plus, such diets have not consistently shown to help with weight management over the long term ^1,2,3.

Carbs can be found in wholegrain pasta, bread, rice, quinoa, barley, dairy, all vegetables and all fruits. Of course, you should avoid simple sugars in sweets, juices, soda, refined grains and baked goods. Sugar won’t give you enough energy to get through barre, but have a simple sandwich or pasta with veggies, and you’ll dance strong all the way through grande allegro. You won’t get that same level of sustained energy from a protein shake, or a big piece of meat before class.

Weight management and carbohydrates

The main reason people believe the hype about low-carb diets like Atkins, South Beach and Paleo diets is that they do aid in weight loss…. at first. For most people, much of the weight is gained back often with a few extra pounds to spare¹. Yo- yo dieting is not what dancers need, especially when it is at the expense of their health or performance. Quick weight loss, a hallmark of low-carb diets, can lead to loss of lean mass (muscle). Going on any very low-calorie diet and losing muscle means losing the most metabolically active tissue the body has. In addition to lowering the metabolic rate, the body adjusts to the restricted calories, setting one up for an endless cycle of gaining and losing. A better strategy would be to limit simple sugars and eat smaller more frequent meals and snacks with fruits, vegetables, whole grains and legumes as the foundation.

Carbohydrates and performance

There is no better fuel for athletic performance and brain function than carbohydrates. Complex carbs in whole grains, vegetables and fruits give the muscles a prolonged source of energy. It has been found that giving athletes carb-based snack bars between meals results in better energy output and anaerobic power, while keeping weight the same and lowering body fat⁴.

In one study carbohydrate intake prior to exercise was shown to be as effective in improving repeated jump height as the supplement creatine ⁵. The carb group didn’t gain weight but the creatine group did⁵. The American College of Sports Medicine recommends that athletes get 55-60% of their total calories from carbohydrates, and whole grains are also important sources of fiber, B-vitamins, iron and folate.

How much, and when?

Here are a few real-life examples:   

Everyone is different, but if 2000 calories are needed then 55-60% should come from carbs. That is about 275-300 grams because carbs have 4 calories per gram. Carb needs can also be calculated based on grams per kilogram of body weight. In general, recommendations are 5-8 g/kg depending on intensity of activity. So a 120lb (54.5kg) female dancer would need at least 272 grams per day.

Examples:
1 piece of bread: 12-17 grams
1 apple: 25-30 grams
1 cup quinoa or brown rice: 39-45 grams
1 cup green beans 8 grams

Long, busy class and rehearsal days

Plan ahead so that carbs and protein are eaten within one hour post exercise the day before.  Carbs should be eaten in the range of 30-60 grams per hour during the rehearsal day.

Show or audition day

If a dancer is feeling nervous and doesn’t want food sitting on their stomach, then they should be well-fueled 3-4 hours prior to the show/ audition. Then an hour or so before, opt for easy to digest carbs like pretzels, crackers or a sports beverage. High-fat and high protein foods take a bit longer to digest, so eat these in moderation if you’re nervous. Re-fuel as needed if it is a long show.

Rest day

On well-deserved days off, a dancer still needs carbs but not in the same amount as a workday.  Cut back just a little bit, and eat lots of fruits and veggies.

The subject of carbohydrate intake is big, and can’t be covered in one article. Check out my earlier Dance Informa article on glycaemic index for additional information.

Even mild dehydration can affect performance.  Staying hydrated is extremely important to a dancer’s performance because the first signs of dehydration are fatigue and poor balance.  Thirst actually only kicks in after the body has lost 1-2 litres of water. If you are thirsty then you are already dehydrated.

The science

Water makes up approximately 60% of body weight and is the largest component of the human body.  The muscles we work so hard to develop as dancers (skeletal muscles) are about 73% water, your blood is about 93% water and even bones and teeth contain some water. Water is critical for maintaining homeostasis within the body and important in the thousands of biochemical and physiological functions our bodies go through every day. Water aids in digestion and is important in the transport and elimination systems of the body.

Overheating and performance

It’s important for dancers to know that being properly hydrated helps keep the body from overheating. Helping the body promote heat loss when dancing full out will improve athletic performance and aid in recovery. This is especially important for dancers wearing hot costumes and performing under stage lights. Sweat losses during performance can be significantly more than during rehearsal of the same piece. This is why drinking regularly (even small, regular sips) is an important habit during a show.

How much is really needed? Can a dancer get fluids from other things besides water?

The American College of Sports Medicine recommends that athletes (we all know that dancers are athletes) start their exercise already hydrated with about 500ml of beverage taken before you begin. Then drink 150-300ml every 20 minutes or so. This means that your reusable water bottle should be your constant companion in the studio or backstage.  Every dancer is a little different but pre-professional and professional level dancers should aim for about 2800-3500ml of fluids every day.  That’s about 12 – 15 cups.  About 20-25% will come from foods like fruits and veggies, but about 80% comes from what you drink.  Aim to get most of your fluids through water, but juices, sports drinks, and even tea and coffee can be counted toward that goal. Some dancers find that mixing 50% sports drink with 50% water in their reusable bottles helps them get through long rehearsals or classes. This is because sports beverages contain a source of readily available energy (calories) and electrolytes that are lost in sweat.

But I want something besides just water…..

Prevent dehydration by eating lots of fruits and veggies.  Consider melon, squash, oranges, apples, pears, grapes, leafy greens and salads in addition to beverages like tea, whole fruit ice-blocks, sports drinks, smoothies, soy milk, almond milk, and yoghurts.

What about caffeine?

Caffeine makes us more awake and is known to enhance athletic performance. But there can be too much of a “good” thing.  Caffeine is a central nervous system stimulant, not a source of energy.  Yes, caffeine can also promote water loss and dancers should limit caffeine, but those beverages can still count toward your daily intake. I always recommend limiting or avoiding soft drinks. They are empty calorie bombs and can make bones weaker.  One cup of coffee is fine, but being overly jittery doesn’t help your dancing.

So be good to your body and good to the earth by taking your reusable water bottle with you everywhere and refilling it often!
