Which of the following is a recommended practice for enhanced carbohydrate oxidation during exercise?

Employing multiple transportable carbohydrates during exercise is a recommended practice for enhancing carbohydrate oxidation. This approach takes advantage of the body’s ability to utilize different types of carbohydrates more efficiently. When multiple carbohydrates, such as glucose and fructose, are ingested simultaneously, they can be transported via different pathways, which may help increase the amount of carbohydrates that can be oxidized during prolonged or high-intensity exercise.

The rationale behind this practice is that glucose and fructose use different transporters in the intestines, allowing for higher overall absorption rates. Consequently, this can lead to improved performance and endurance by providing a steady supply of energy that matches the demands of the body during prolonged activity. Research supports that consuming a mix of carbohydrates can enhance exercise performance compared to consuming a single type.

Other choices involve less effective strategies. For instance, relying solely on glucose or fructose limits the potential energy production and does not maximize the benefits of various transport systems. Avoiding carbohydrate intake altogether would hinder performance due to insufficient energy availability for exercise, particularly in endurance events. Thus, using multiple transportable carbs is clearly the optimal choice for enhancing carbohydrate oxidation during exercise.
