Sports Nutrition for Athletes: Why You Need More Carbs to Perform at Your Best

There is still an irrational fear of carbohydrates in sports nutrition, and it needs to end.

Some athletes, especially female athletes, have been taught to view carbs as something they should minimize or avoid if they want to stay lean. The problem? Carbohydrates are not the enemy. They are fuel.

A lot of the fear-mongering around carbs came from oversimplified and poorly informed nutrition advice that treated carbohydrates as the primary reason people gain body fat. For athletes, this can be especially damaging. When you dramatically reduce carbohydrates while demanding high levels of speed, strength, power, and conditioning from your body, you can end up taking away one of your most important performance resources.

If you want to perform like an athlete, you need to fuel like one. Make sure to go read our article on post-workout protein!

Carbohydrates Are Performance Fuel

Your body uses several energy systems to produce ATP, the energy your muscles need to contract and produce force.

For explosive athletes, the ATP-PC system and anaerobic glycolytic system are especially important.

Think about a 30-yard sprint, a maximal vertical jump, a hard defensive slide, a powerful change of direction, or a series of repeated explosive plays. These efforts are short and intense. Your muscles need to produce enormous amounts of force in a very short period of time.

Carbohydrates play a major role in supporting these high-intensity efforts because muscle glycogen, the stored form of carbohydrate in your muscles, is a major fuel source when intensity rises.

And here’s where things become important.

Most sports aren’t one sprint.

They’re sprint → recover → sprint → cut → jump → accelerate → decelerate → repeat.

Your muscles have to repeatedly produce high levels of force. If you consistently under fuel your body and don’t replenish glycogen, you’re making it harder for your muscles to repeatedly perform at the level your sport demands.

Why You Feel Slow and Sluggish

Ever had a training session where everything feels heavy?

Your legs feel dead. Your sprint times are slower. You don’t have the same pop in your jumps. Lifts feel unusually difficult. You feel like you’re working hard but can’t produce the same speed or explosiveness.

Sometimes the problem isn’t your training program.

You simply aren’t fueled properly.

Athletes often try to solve this by adding more caffeine, pushing harder, or blaming themselves for having a bad workout.

But if you’re consistently under-consuming carbohydrates, your muscles may simply not have the fuel they need to perform repeated high-intensity work.

This doesn’t mean carbs magically make you faster overnight. It means proper carbohydrate intake helps provide the fuel necessary to train hard, recover, and repeatedly express speed and power.

Under-Fueling Can Affect More Than Performance

This is where sports nutrition becomes more than simply optimizing your performance.

If your muscles are constantly fatigued because you’re not adequately fueling your training, your ability to produce and absorb force can be compromised.

An athlete who is fatigued may not move with the same coordination, stiffness, explosiveness, or control as they normally would.

And when you continue asking a fatigued body to sprint, jump, cut, decelerate, and produce maximal force, you can potentially increase stress on the tissues involved.

That includes muscles, connective tissue, and tendons.

This doesn’t mean eating more carbs guarantees injury prevention. Injury is multifactorial. But consistently under fueling while demanding high performance from your body is certainly not a strategy for becoming a more durable athlete.

You cannot expect your body to perform at its highest level while constantly running on empty.

Athletes Need to Stop Fearing Carbs

If you’re an athlete, carbohydrates shouldn’t automatically be something you try to eliminate.

Rice. Potatoes. Oats. Fruit. Pasta. Whole grains. Other carbohydrate-rich foods.

These can all have a place in a performance-focused nutrition plan.

The exact amount you need depends on your body size, sport, training volume, goals, and overall diet. But many athletes would benefit from eating significantly more carbohydrates than they currently do, particularly around demanding training sessions and competition.

Stop thinking about carbs exclusively through the lens of weight loss.

Start thinking about them through the lens of performance.

Your goal isn’t simply to be lighter.

Your goal is to be faster, stronger, more explosive, more durable, and better at your sport.

Final Thoughts

Great training requires great fuel.

You can have the best speed program in the world, but if you’re consistently under-fueled, you’re putting a ceiling on how well you can train and perform.

Carbohydrates aren’t something athletes should irrationally fear. They’re an important part of sports nutrition and can help provide the fuel necessary to train, compete, recover, and repeatedly express high levels of power.
