Is Your Athlete at Risk of Caffeine Poisoning?

EducatorsParents

Laura Lewis headshot.Caffeine, especially in soft drinks or energy drinks, may seem relatively benign. But it can have detrimental effects on your athlete, and in some cases, it can even be deadly. Here, the U.S. Anti-Doping Agency’s (USADA) Director of Science, Laura Lewis, PhD, explains what you need to know to keep your athletes safe when it comes to caffeine intake, and how to help them improve their energy without relying on caffeine.

 

Caffeine can be fatal

If an athlete does consume too much caffeine, the result can be fatal. In 2018, one study identified more than 90 caffeine-related deaths, and athletes made up a large percentage of the fatalities. Teen athletes trying to stay alert are particularly susceptible to taking extraneous caffeine supplements like pills and powders on top of energy drinks, but even energy drinks on their own can have fatal consequences if consumed in excess. (To clarify, it’s rarely a caffeine overdose per se that causes the death. Rather, it’s a cardiac event triggered by the caffeine consumption.)

 

How much is too much?

Everyone responds to caffeine differently. Unfortunately, while there are recommended maximum caffeine intake amounts for different age groups, there is no specific “overdose” threshold for caffeine because people respond to it differently.

Lewis explains that certain people process caffeine faster, so the effects of caffeine in a cup of coffee in the morning can wear off within as little as 90 minutes. But for slower caffeine metabolizers, that caffeine can linger in the system for up to nine hours. If an athlete has another energy drink at lunch, the resulting caffeine levels may be more elevated than they realize. The ‘alert’ feeling that comes from caffeine also may take more or less time to be felt, depending on how the body responds to caffeine. That means a cup of coffee may not provide that ‘perky’ feeling for an hour, or it may be felt almost instantly.

 

What are signs of a caffeine overdose?

Mount Sinai Hospital does refer to the detrimental effects of too much caffeine as an ‘overdose.’ Symptoms include a racing or irregular heartbeat, muscle twitching, nausea, trouble focusing, difficulty breathing, seizures, dizziness, and even confusion or hallucinations. In these cases, seek immediate medical help. Also, if possible, ask the athlete what caffeine they have ingested so that you’re better able to communicate the situation to medical professionals.

 

How much caffeine can a young athlete safely consume?

However, unless your athlete avoids any soda or chocolate (among many other foods and beverages), it’s likely that they are ingesting some caffeine. Johns Hopkins University’s website notes that while the American Academy of Pediatrics says that no amount of caffeine is safe, the Canadian recommendations are a bit more nuanced and suggest that teens can safely consume 85 to 100 milligrams of caffeine per day—or roughly two cups of coffee. That amount, however, is lower than the amount found in most energy drinks and certainly in any pills or powders.

Even below the ‘overdose’ amount, caffeine can cause negative side effects, says Lewis. Things like headache and diarrhea, as well as a jittery feeling, are common for young athletes who’ve consumed too much caffeine.

 

How can an athlete keep track of caffeine intake?

It can be extremely hard to keep track of caffeine intake because often, it’s not clear—especially for athletes who opt for coffee. Most energy drinks will list caffeine content on the nutrition label, but brewed coffee can be tricky. Sometimes, it’s hard to tell how much caffeine you’re getting in a drink from a coffee shop, says Lewis. “A lot of the time, you hear that a cup of coffee is around 50 milligrams of caffeine, but that’s for eight ounces of that particular coffee. A drink from a coffee shop can easily have four times that amount depending on the size and type.”

“Overdosing doesn’t just happen from taking caffeine pills or powders,” Lewis notes. “It can still happen when you have a coffee from a shop, and then an energy drink, and a different energy drink an hour later. Suddenly, you have this huge amount of caffeine in your system without any intention of overdoing it.”

Because of that, operate on the assumption of ‘less is more.’ If your athletes are taking in caffeine, also help them better understand the impacts, says Lewis. Have athletes note the time that they’re having any drinks that contain caffeine, and then add notes about alertness, issues sleeping, and any negative impacts. This will help them learn how to best manage any caffeine intake.

 

What if an athlete needs caffeine to stay alert for practice?

If an athlete is insisting that they ‘need’ caffeine in order to perform, Lewis says that focusing on the ‘why’ is more important than trying to dial in an appropriate amount of caffeine. “If your athlete is tired all the time, and you’re wanting them to be more alert, it’s easy to see how caffeine could be used to mask those issues,” she says. “But what’s the real problem? It’s likely that they need more sleep and rest, not more caffeine. And by having caffeine, the athlete is in this negative cycle because caffeine affects sleep. So, then they’re not getting enough sleep, but they think they need more caffeine to be alert, but then they can’t sleep again. They’re stuck in this negative habit loop.”

She also adds that if your athlete is struggling to feel alert and ‘on’ at practice, a carbohydrate-rich snack beforehand could be more beneficial to their performance and ability to adapt to training than an energy drink when it comes to sustained, healthy energy.

Takeaway

Caffeine can be dangerous for a young athlete, with the effects ranging from the jitters to death. While no amount is recommended for young athletes, it’s important for athletes to understand how caffeine impacts them, since it’s found in many common drinks and even foods. It’s also important for athletes to understand how they can use rest and non-caffeinated products to feel their best.

Goal-Setting Lesson Video Transcript

Hi. I’m Trevon, Trey, Jennifer. Team USA wheelchair basketball player, paralympian, and true sport athlete. Today, I want to talk to you about goal setting. And there are three things that I would like you to know. First, successful athletes set goals and a planned roadmap. Second, goals should be written down, assessed over time, and changed if necessary. And third, goals need to be challenging in order to be worthwhile. As a freshmen at Edinboro University, I was a part of a team that made the national championship game. And at that time I recognized I was the low man on the totem pole, but I felt in my heart that I knew my dreams were so much bigger than winning a national title. I wanted to make Team USA. I knew what achieving my lofty goal was not going to be easy and that I would need to work hard every day.

So, as a reminder, I created a pyramid of goals that I kept right above my bed. This pyramid reminded me of the accomplishments that I was working towards and visually represented my need to create a solid foundation underneath me before reaching the top. In the bottom roll of my pyramid of goals I listed goals such as obtaining my bachelor’s degree, becoming a scholar athlete award recipient, and becoming an All-American. The middle row listed winning a national title and playing for a professional team. And at the top row, the most challenging of them all, I listed becoming a gold medalist for Team USA.

By understanding that there are smaller stepping stones to achieving my ultimate goal of being on Team USA, I was able to stay motivated and to stay focused on completing the smaller stepping stones fully before moving onto the next one. Now I’ll be the first to admit that not every goal that I listed on my pyramid was accomplished, but seeing my goals every day when I went to bed, I was able to push through the days that I felt like doing nothing in hopes of achieving the bigger picture. Remember, create a clear goal roadmap, assess your goals often, and continue to challenge yourself. I hope that you never stopped dreaming big or reaching for the stars. And I look forward to seeing where your roadmap takes you.

Body Image Lesson Video Transcript

Hi, I’m Kara Winger, Olympic javelin thrower, and true sport athlete. Today I want to talk to you about body image and I have three things I’d like you to know. First, healthy thoughts often lead to healthier bodies. Second, there are varying body types and no one’s body is exactly like another. And third, true beauty goes deeper than the skin. As a multi-time Olympian, I’ve experienced a lot of variation and progression in my training. My coaches and I adapt to my training frequently, all with the goal of supporting my long-term success and health in the sport of javelin. I’m talking to you about body image today because sometimes even with the best of intentions and a common goal in mind, the changes you make to your training habits can prove to be detrimental if made for the wrong reasons. In the lead up to the 2012 Olympic trials, I was told in order to improve my performance on the field, I should try to become a leaner, skinnier version of myself.

So I changed my diet. I went along with what I was being told to do, even though I’d had great success at a slightly heavier weight and higher body fat percentage, and became much leaner than ever before. It seemed like a successful change at first, but I didn’t have nearly the results I’d had before. And I believe becoming leaner than my body naturally wanted to be was what caused my ACL to tear. In the end, it cost me heavily going into the 2012 London games. The takeaway for me, and hopefully for you, is that it’s important to know what works for you and your body and to not compare yourself to others. You should do your research and experiment with your diet to find what makes you feel the best, rather than focusing on what you look like. Today, if I feel like having a chocolate chip cookie, I have one, just not every day.

I’ve learned what a properly balanced meal for my body looks like and I recognize food as the fuel that keeps me throwing. I hydrate and allow myself time to recover. And I listen to and communicate with my body so that I can be the best version of myself. In the end, you are in control of how you see, treat, and respond to your body. We only get one and it’s amazing to discover how many things our bodies can do. Be a true sport athlete. Love who you are in this moment and get excited for all the places your body will take you.

A Good Sport Lesson Video Transcript

Hi, I’m Izy Isaksen, Team USA, Modern Pentathlon, Olympian, US Army Sergeant, and True Sport Ambassador. Today, I want to talk to you about being a good sport. There are three things I’d like you to know. First, real winners act the same toward their opponent, whether they win or lose. Second, follow the rules and be a gracious winner and respectful loser. And third, sportsmanship reveals your true character.

I started competing in Modern Pentathlon eight years after my older sister and three-time Olympian, Margaux Isaksen, began competing. I soon realized that people often compared the two of us. I would overhear spectators and teammates asking, “Who’s the better athlete,” and “Who’s going to beat the other.” Instead of letting outside pressures create a negative experience for us, I chose to practice winning and losing with grace and respect. I know that it would have been easy to let our hyper competitive mindset affect our relationship, but instead we decided to support and cheer for each other, regardless of our own performance. My experience of competing against and being compared to my older sister, taught me to focus on how to perform at my best, rather than putting wasted energy into wishing for others to fail.

I believe that sportsmanship reveals true character. So, no matter what situation I encounter during competition, I know it’s important to always treat people with respect and be a good sport. Remember, be a fierce competitor, find grace in all your victories and losses. And I hope to see you out there.

What Kind of Coach Do You Want to Be? Video Transcript

Edwin Moses: You’re a coach. Maybe what you want is very simple, for everyone to just run in the right direction, score for their own team, to try and try again and again. Maybe you want your athletes to become all stars. You want them to earn trophies, medals, win titles. You want them to reach the highest height their sport allows. And wanting all of that, of course, that’s good. But as every great coach discovers, developing a great athlete means nurturing, nurturing the even greater person within. Truth is, you have even more influence than you know.

You have the ability to affect even deeper change, to take what’s in your hands and do something even more extraordinary. You can be both the coach who provides the skills needed to win the game and the coach who helps them learn and succeed beyond the sport, to become all stars wherever they land in the future, and to enjoy their lives more now, because the confidence and courage they find working with you will stay with them when they need it the most. There are games to be won, lives to change. Coaches have the power to do both.

I’m Edwin Moses, and the lessons I’ve learned through sport have challenged me, guided me, and shaped my life forever. What kind of coach do you want to be?

THE SIMPLE TRUTH: DECODING THE SUPPLEMENT INDUSTRY VIDEO TRANSCRIPT

At first glance, dietary supplements look the same. They seem safe and healthy, but just because the label says a product is a dietary supplement, that doesn’t mean it’s safe. Unfortunately, you can’t tell whether a product is safe or not just by looking at the label. Most vitamins, minerals, fish oil, and other supplements containing nutrients are probably just fine, but supplements are not evaluated or approved by FDA before they are sold. Although it is rare for vitamins or minerals to be contaminated with drugs, there has been at least one case of a vitamin containing an anabolic steroid.

At the other extreme are products that contain drugs, stimulants, anabolic steroids, or other hormones. Even though these are not technically dietary supplements, many of them are labeled as supplements. For example, body-building products sometimes contain anabolic steroids or Selective Androgen Receptor Modulators, known as SARMs, or other hormones. Some pre-workout or energy products contain illegal stimulants like DMAA, ephedra, or other amphetamine-like stimulants. Weight loss products might contain prescription drugs like sibutramine, or hormones, like human chorionic gonadotropin, also known as hCG. All natural or herbal sexual enhancement products might contain hormones or Viagra-like drugs. Products like these can harm your health and career, but they’re for sale online, in some nutrition stores, and they’re labeled as dietary supplements.

When you pick up a supplement, especially one that promises performance enhancement, you don’t know if it belongs in the “Mostly O.K.” pile or in the “Dangerous” pile. After all, two products might look the same, but one might contain just amino acids and other legitimate ingredients, while the other also contains anabolic steroids. Because of this, FDA has issued a warning about certain categories of supplements: body building products, weight loss products, and sexual enhancement products. Be extremely careful when considering a supplement in one of these categories. We strongly recommend that you avoid products in these categories.

Even when FDA tests supplements and finds dangerous ingredients, companies sometimes refuse to recall them. Sometimes, they simply repackage their product and continue selling it under a new name. Just because a product is on a store shelf doesn’t mean it is safe. You need to do your research and be an informed consumer. The dietary supplement industry is enormous. Supplements that appear to be safe could actually be dangerous products in disguise. If you use dietary supplements without doing your research, you may be taking serious risks with your health and your career.
