Creatine supplementation improves all of the following variables EXCEPT

• A. Lean body mass
• B. Maximal strength
• C. Endurance performance
• D. Power

Answer: (C)

Creatine raises intramuscular phosphocreatine stores, strengthening the phosphagen energy system that fuels short, high‑intensity efforts. This lets you lift heavier, perform more reps, and generate higher peak power during workouts, which over time leads to greater lean body mass and improved maximal strength. Power also benefits because it hinges on quick, high-force outputs that rely on rapid ATP turnover supported by those phosphocreatine reserves. Endurance performance, however, depends mainly on aerobic metabolism and sustained energy production over longer periods. The phosphagen system isn’t the limiting factor there, so creatine doesn’t reliably increase VO2max or time-to-exhaustion for steady-state endurance efforts. While you may see tiny gains in very brief repeated-sprint scenarios, long-duration endurance performance doesn’t typically improve with creatine supplementation.
