Caffeine | Should Youth Athletes Consume It?

Exploring the impact of caffeine consumption in youth sports reveals a complex landscape. With caffeine benefits for young athletes being a topic of increasing interest, it's crucial to understand how this intersects with Sports nutrition and caffeine. While the potential caffeine side effects in teenage athletes cannot be overlooked, establishing clear guidelines for caffeine intake in youth sports is essential for informed decisions. This article delves into these dimensions, addressing the role of caffeine in the lives of young athletes.

When you think of caffeine, your first thoughts are probably about your morning cup of coffee or the cups of tea you drink throughout the day. But did you know that it’s also one of the most readily available and commonly used sports supplements too? Claims of performance-enhancing effects are supported by lots of scientific literature and include increasing alertness and concentration and reducing fatigue. And it’s not just used by older athletes either. In fact, 83% of teenagers report regularly consuming caffeine in the form of fizzy drinks, coffee and energy drinks [2]. But is it effective in youth athletes and do these products have a place in their diet and training plan?

What is Caffeine?

Caffeine is a compound that occurs naturally in plants and is commonly found in lots of different food and drinks including cocoa, coffee, tea, fizzy drinks and energy drinks [2]. It’s a stimulant that, simply put, affects the natural fight or flight response in the body. This increases feelings of alertness and concentration and combats fatigue [1].

Does Caffeine Improve Performance?

Athletes from many different sports regularly use caffeine as an ergogenic aid (a supplement that enhances performance) before an event or training session.

Consuming caffeine can [1]:

  • Increase alertness
  • Improve reaction times
  • Reduce perceived exertion
  • Mask feelings of fatigue
  • Increase muscle force production
  • Increase endurance capacity

All of which act to make the athlete feel more switched on and like they can work harder and for longer. Sounds ideal right? But the catch is that individuals will respond very differently to the same amount of caffeine and there’s very little evidence of its performance or health effects in youth athletes.

What About For Youth Athletes?

There is some evidence to suggest that caffeine may have a similar beneficial effect in youth athletes to adult athletes. Benefits that have been reported include improvements to; jumping, running, sprinting, reaction times, physical performance and upper body strength and reductions to the rate of perceived exertion in footballers, judo athletes and tennis players [3,4,5,6].

However, it’s very important to understand that unlike in adult athletes, the effects of caffeine supplements in youth athletes is not a very well researched area at all.

Can You Have Too Much Caffeine?

Drinking too much caffeine in a short space of time can actually negatively affect an athlete’s performance. It can cause various side effects including:

  • Jitteriness
  • Nervousness
  • Dizziness
  • An inability to focus
  • Difficulty concentrating
  • Nausea

And many other effects which have resulted in sales of energy drinks being banned to under 16’s in the UK.

Should Youth Athletes Take Caffeine Supplements?

While there certainly may be some benefits to caffeine supplementation for youth athletes, supplementation should only ever be considered when the whole diet has been perfected first. If athletes need an energy drink or caffeine shot just to get them through the training session, then alarm bells should be ringing. If this is the case, athletes need to look at their whole food diet first and foremost rather than trying to find a quick fix solution.

If their nutrition is totally nailed, there could certainly be some benefit to older youth athletes if taken in the correct amounts and caffeine supplements might help give them that edge in competition or training.

Like with any supplements, we always recommend seeking advice from a registered sports nutritionist before implementing them into a youth athletes’ diet. Caffeine should only be considered for those aged 16 and over and any supplements used must be recognised and approved by Informed Sport.
