Choosing the ideal carbohydrate gel goes far beyond flavor or brand. The decision involves understanding the type of training or competition, the duration of the exercise, the intensity, the gastrointestinal tolerance, and the athlete's nutritional strategy. In endurance sports such as running, cycling, and triathlon, the right gel can directly impact performance.
Difference between training gel and race gel
During training, gels play an important role in testing nutritional strategies. It is at this time that the athlete evaluates gastrointestinal tolerance, the flavor that works best, and how the body responds to carbohydrate consumption in motion.
In short workouts, the use of gels is often not essential. However, in long workouts, it becomes a tool to train the gut and adapt the body to carbohydrate consumption during exercise.
In the race, the logic changes. The gel used should be one that has been previously tested, with a known composition and aligned with the planned strategy. Choosing the gel on race day based solely on taste can increase the risk of gastrointestinal discomfort and decreased performance.
How to adjust gel usage to the duration and intensity of exercise.
In short-duration, high-intensity exercises, the need for carbohydrates during exertion is lower, but strategic use can make a difference in events lasting close to 60 minutes.
In medium-duration exercises, regular carbohydrate consumption helps maintain intensity and delay fatigue, making gels a useful tool.
In long, continuous events such as marathons, long bike rides, and triathlons, adequate carbohydrate intake over time is even more important. The intensity of the exercise directly influences intestinal absorption and the hourly carbohydrate requirement, reinforcing the importance of a well-defined strategy.
Recent scientific evidence shows that nutritional strategies that consider carbohydrate intake in a planned way can contribute to maintaining performance in endurance athletes. A systematic review and meta-analysis published in 2021 in the Journal of the International Society of Sports Nutrition analyzed nutritional interventions involving carbohydrates in trained athletes and highlighted how different consumption approaches can influence adaptations and performance in endurance sports such as running, cycling, and triathlon, especially in prolonged efforts.
Most common mistakes when choosing gel
Some mistakes are common and can compromise an athlete's nutritional strategy.
Using caffeine without planning can lead to unwanted side effects such as gastrointestinal discomfort or excessive changes in heart rate. Failing to consider carbohydrate intake during exercise can result in insufficient energy during the workout.
Testing a new gel directly during a race increases the risk of intolerance. Ignoring factors such as heat, humidity, and sweat rate can lead to dehydration and decreased performance.
How to combine gel with other carbohydrate forms
In longer races, combining gels with other carbohydrate sources can be an effective strategy.
Consuming gels along with sports drinks helps to better distribute carbohydrate and fluid intake over time. Using gels along with an electrolyte replacement drink can help maintain hydration and sodium balance, especially in conditions of intense heat.
Mixed strategies are especially useful in long-distance running, cycling, and triathlon, improving absorption and gastrointestinal comfort.
Application by sport modality
In running, the strategy for using gels varies depending on the race distance. Short races require fewer interventions, while medium and long races demand planning for gel consumption throughout the course.
In cycling, the continuous consumption of carbohydrates over time facilitates the maintenance of energy and reduces fluctuations in performance.
In triathlon, strategy must consider the transitions and accumulated fatigue between the swimming, cycling, and running disciplines, adjusting gel use according to each segment to maintain performance until the end.
Conclusion
There is no one-size-fits-all gel that works for all athletes and situations. The best gel is the one that fits the nutritional strategy, the sport, the duration of exercise, and individual tolerance. Choosing the right gel is part of performance planning, not a last-minute detail.
