What is a significant factor for maximizing glycogen storage before competition?

The significant factor for maximizing glycogen storage before competition is high volume, heavy resistance training. Engaging in this type of training can lead to an increase in muscle glycogen stores due to the anabolic response and physiological adaptations that occur with heavy lifting. Resistance training enhances glycogen synthesis by increasing the muscle's capacity to store glycogen and facilitates the enzymatic activity related to glycogen metabolism.

Additionally, heavy resistance training can stimulate glucose uptake by muscles, especially when followed by an adequate recovery period and appropriate nutrition, including carbohydrate intake. This strategic approach ensures that muscles are primed for optimal glycogen storage, which is critical for sustained energy during athletic performance.

Other choices present factors that are less relevant to maximizing glycogen storage immediately before competition. Protein supplements primarily support muscle repair and recovery rather than directly influencing glycogen storage. Increased carbohydrate intake post-exercise does help to replenish glycogen stores after workouts, but it does not maximize stores in the pre-competition phase. Lastly, while aerobic exercises can improve overall fitness and endurance, they do not specifically enhance glycogen storage as effectively as heavy resistance training in the context of preparing for competition.
