Debunking Common Sports Nutrition Myths

Debunking Common Sports Nutrition Myths

In the world of sports and fitness, nutrition plays a pivotal role in optimizing performance, aiding recovery, and sustaining overall health. However, amidst the plethora of information available to us, certain myths and misconceptions often cause confusion and misunderstanding.

From outdated beliefs about protein consumption to misconceived notions about hydration, these myths can lead athletes astray, hindering their progress and potentially jeopardizing their performance.

We are going to debunk some of the most common sports nutrition myths.

1- Caffeine is bad for you.

Although caffeine shouldn’t be consumed in excess, a small amount can have benefits for athletes. Caffeine improves alertness and can provide a much-needed final boost at the end of a long race.

2- Carb Loading.

While not a total myth, carb loading is widely misunderstood. Most people think carb loading means increasing the volume of food you eat before a race. What you should actually be aiming to do is increase the carb content of your food while keeping the volume the same.

3-Lean athletes are faster.

Many athletes think they must stay lean to be fast and therefore avoid weight/strength training fearing that gaining muscle mass will slow them down. This simply isn’t true.

Strong muscles give you more power to run faster, while a lack of muscle mass can impair performance and makes you more susceptible to injury.

4- A vegan/vegetarian diet can’t support athletic performance and recovery.

A quick Google search will show you that there are many successful vegan and vegetarian athletes. With plenty of plant-based sources of carbs (for energy) and protein (for recovery), there’s no reason people who follow a more plant-based diet can’t also perform well athletically.

Plant based sources of protein include lentils, beans, chickpeas, nuts, & seeds.

5- Athletes need to eat a lot of protein.

Protein aids repair and recovery for athletes after long workouts. However, eating excessive amounts of protein isn’t particularly beneficial. Most people can only absorb around 30-40g of protein in one sitting.

Athletes should aim for around 30-35% of their calories to come from protein, making sure not to skip other key nutrients.

6- You need to fuel on every run.

In most cases if you’re running for less than an hour you don’t need to use race fuel like energy drinks or energy gels. While fuel and nutrition have their place in training, they should mainly be reserved for longer runs.

7- You must eat immediately after a workout.

It’s a common misconception that you must eat immediately after a workout, as long as you can eat something within an hour of exercise you’ll be fine.

In this 1-hour window the body is more receptive to nutrients, however not all athletes can stomach solid foods straight away and some may prefer a recovery drink to kickstart things.

8- Fasted workouts help weight loss.

The ‘fasted workout’ has become a bit of a trend recently, promoting working out on an empty stomach to maximise weight loss. In fact, there is no evidence to support these claims and working out without eating will most likely hinder your performance as you won’t have enough energy.

You also risk feeling nauseas or lightheaded as your blood sugar levels can drop dramatically.

9- The ‘perfect’ nutrition formula.

The idea that there is a perfect formula for all athletes is simply untrue. Nutrition is so personal that a one size fits all approach isn’t possible.

While somebody else’s nutrition plan might seem like it’s working for you, unless you experiment for yourself you may never unlock your full performance potential.

10- You need to drink 8 glasses of water every day.

While drinking plenty of water and staying hydrated is important for athletes, 8 glasses of water a day isn’t always necessary and everybody’s needs are different depending on their size, age, etc.

During exercise sweating causes electrolyte loss, these need to be replaced by electrolyte supplements. If you drink too much water without replacing electrolytes your blood sodium becomes diluted and you become at risk of developing Hyponatremia.
