Why Glucose Matters When it Comes to Athletes
Your body stores glucose, ready to be burned the moment you start exercising, whether it's a long bike ride, a brisk jog or a refreshing swim.
When you're exercising, particularly for an extended period, your glucose will go up for a time.
"When someone is early in a workout — and they're exercising at high intensity — they'll actually see a rise in glucose. That's the body responding to the stress of the event," said Jim McCarter, medical affairs director for Abbott.
That's how it starts, but not how it ends.
"Later in exercise — and especially in endurance exercise — as glycogen stores are depleted, glucose will begin to lower. And that’s especially important in long-distance endurance events," McCarter said.
Understanding real-time glucose levels can help athletes know what to consume and when, which helps improve muscle recovery and athletic performance, Swedish research shows.4 And athletes who understand the impact of what they eat and drink will have a better chance of improving their performance, according to an American College of Sports Medicine study.
Putting these concepts to the test, cyclists from some of the top teams at the Tour de France, the world’s largest annual sporting event, wore Libre Sense in training as part of an observational trial. This technology enabled the athletes to track their glucose data to help inform them when it may be time to refuel, as they prepared for the race.
"FreeStyle Libre changed the way millions of people manage their diabetes to get and stay healthier, and now with Libre Sense we're bringing that same proven technology to empower athletes to help them reach their athletic performance goals," Watkin said.
Abbott's Libre Sense will be available in the coming weeks. It will initially be made available across eight European countries: Austria, France, Germany, Ireland, Italy, Luxembourg, Switzerland and the United Kingdom.
