Should Athletes Turn to Energy Drinks for Enhanced Performance?

October 21, 2022

Sports fans may notice a new beverage in the hands of their favorite NFL players this season. The new Gatorade energy drink, aptly named "Fast Twitch," is available exclusively on the sidelines of NFL games (for now). Fast Twitch tastes similar to regular Gatorade but contains a blend of electrolytes, B-vitamins and 200 milligrams of caffeine - double the caffeine content of Red Bull. It's set to hit shelves in February 2023. As more athletes turn to energy drinks to enhance their athletic performance, it begs the question - are those drinks really helping? > Connect with the Sports Health team at the Bone & Joint Institute

How do energy drinks affect performance?

The primary ingredient in energy drinks is caffeine. But they generally pack much more of a punch than other types of caffeinated beverages:
  • Soda - 40 mg
  • Coffee (8 oz.) - 95 mg
  • Red Bull - 80 mg
  • Monster - 160 mg
  • 5 Hour Energy Shot 200 mg
  • Bang Energy - 300 mg
“It gives the sense of increased energy when athletes are tired or exercising, which is why they often use them,” said Stephanie Saucier, MD a cardiologist with Hartford HealthCare’s Heart and Vascular Institute. Young athletes can be even more vulnerable. “Those under the age of 18, overall, have a lower tolerance to caffeine in general," said Dr. Saucier. "They can really feel the side effects from the energy drinks and are more prone to adverse effects, especially if they are drinking more than one." > Want more health news?

What else is in energy drinks?

In addition to caffeine, energy drinks contain other listed or unlisted stimulants and ingredients that compound the effects of caffeine, such as:
  • Guarana
  • Ephedra
  • L-carnitine
  • Taurine
  • Ginseng

Some of these substances are also banned or limited for competitive athletes by the NCAA and World Anti-Doping Agency.

  • Heart attack
  • Palpitations
  • Postural orthostatic tachycardia syndrome
  • Sudden cardiac death

What’s the best energy source for athletes?

“Do not reach for a quick fix of a stimulant from energy drinks. Stimulants may temporarily make you ‘feel better,’ but ultimately are just a quick fix and overlook what you actually do need – calories,” said Barrett. “Calories are the best energy source for the body.” Carbohydrates, he added, allow athletes to train harder and recover more easily from strenuous exercise or competition. “To get the most energy going into your sport, get seven to nine hours of sleep, follow a healthy diet and exercise regularly,” Dr. Saucier said. “If someone does want to drink caffeine or a caffeinated beverage, stick to natural forms of caffeine such as ground coffee or tea. It’s not caffeine that’s dangerous, but rather the amount.”
