Using carbo-loading to increase the store of glycogen seems to benefit only those athletes who engage in aerobic activities for?

Carbo-loading is most beneficial for athletes participating in endurance events lasting over 90 minutes, such as marathon running or long-distance cycling. This strategy enhances glycogen storage in muscles, providing a readily available energy source during prolonged aerobic activities. For shorter, high-intensity exercises, the body primarily relies on other energy systems, making carbo-loading less effective. Thus, the advantages of carbo-loading are primarily seen in endurance sports where sustained energy is crucial.
