Creatine supplementation is most associated with enhancing which type of performance?

• A. Long-duration endurance
• B. Muscle flexibility
• C. Short-term high-intensity work
• D. Skill accuracy

Answer: (C)

Creatine supplementation increases the stores of phosphocreatine in muscles, which are used to rapidly regenerate ATP during short bursts of effort. In activities lasting just a few seconds up to about a minute—like sprints, heavy lifts, or explosive jumps—the phosphagen system powers the work, so having more phosphocreatine allows a higher rate of ATP production, enabling greater peak power and more repetitions before fatigue. That’s why it’s most associated with short-term high-intensity work. It doesn’t notably boost long-duration endurance, flexibility, or accuracy, which rely on different energy systems and neuromuscular factors.
