Although the supplements used during training and competition may be the same, the way they are used is not always identical. The goal of a training session is to promote physiological adaptations, whereas the goal of competition is to maximize performance. For this reason, supplementation strategies should be adjusted according to each situation.
Training and Competition Have Different Goals
During training, the focus is on stimulating adaptations that make the body more efficient over time. Depending on the training phase and the type of session, it may be beneficial to vary carbohydrate availability, test nutrition strategies, and train the gastrointestinal tract to better tolerate food and supplement intake during exercise.
In competition, however, the priority is different. The objective is to provide the body with everything it needs to sustain exercise intensity, delay fatigue, and maintain performance from start to finish. In this context, the nutrition strategy is designed to minimize risks and rely only on approaches that have already been tested during training.
Supplementation During Training
Not every training session requires the same supplementation strategy. Short or low-intensity workouts, for example, may not require carbohydrate intake during exercise. On the other hand, long-duration or high-intensity sessions often benefit from carbohydrate consumption to maintain energy availability and help sustain training quality.
Training is also the ideal time to test different products, flavors, dosages, and timing strategies. This allows athletes to identify what works best for them individually while reducing the risk of gastrointestinal discomfort on race day.
In addition, training sessions provide the opportunity to "train the gut." Regular carbohydrate intake during prolonged exercise promotes adaptations that improve carbohydrate absorption and increase tolerance to higher carbohydrate intakes during competition.
Supplementation During Competition
Competition is not the time to try new supplements or make changes to an established nutrition strategy. Instead, athletes should follow the approach that has already been practiced and validated throughout their training.
Carbohydrate intake during endurance events helps maintain blood glucose levels, preserve glycogen stores, and provide rapidly available energy for the working muscles, contributing to delayed fatigue and sustained performance. Depending on the duration and intensity of the event, other strategies such as caffeine, electrolyte replacement, and a structured hydration plan may also be incorporated.
The supplementation plan should consider factors such as event duration, exercise intensity, environmental conditions, elevation gain, and individual tolerance to ensure an adequate supply of energy and fluids throughout the race.
What Changes in Practice?
In most cases, the supplements themselves are the same, but the strategy differs.
During training:
- Test different products, flavors, and carbohydrate amounts.
- Train the gut to tolerate carbohydrate intake.
- Adjust supplement timing.
- Match supplementation to the goal of each training session.
During competition:
- Use only strategies that have been previously tested.
- Prioritize a consistent supply of energy.
- Follow a planned hydration and electrolyte replacement strategy.
- Avoid last-minute changes that could negatively impact performance.
Conclusion
Supplementing for training and supplementing for competition are not exactly the same. Training is the time to test strategies and promote physiological adaptations, while competition requires a well-defined plan based on methods that have already been practiced and validated. Tailoring supplementation to the objective of each situation can improve performance, reduce the risk of gastrointestinal discomfort, and help athletes get the most out of their training.
