Creatine supplementation is known for its effectiveness in enhancing performance in high-intensity, short-duration activities that involve repeated bouts of effort. This includes activities like weightlifting, sprinting, and high-intensity interval training, which require rapid energy production. In the context of sports training, creatine helps to increase the availability of phosphocreatine in muscles, allowing for quicker ATP regeneration, which in turn can boost performance in these types of exertions.

Endurance sports, which include activities such as long-distance running, cycling, and swimming, rely more on aerobic metabolism rather than the phosphagen energy system that creatine enhances. During prolonged endurance activities, the body's primary energy source shifts towards aerobic pathways, which do not utilize creatine to the same extent. As a result, athletes engaged in endurance sports typically do not experience significant performance benefits from creatine supplementation as they would in high-intensity, anaerobic activities.

While team sports can involve both aerobic and anaerobic components, the predominant energy demands during longer periods of sustained activity lean more towards endurance rather than the short bursts that benefit from creatine. Thus, the substantial lack of impact that creatine has on endurance training underscores why it is not beneficial in that specific context.
