Morning coffee may give athletes a real edge, study finds
NCT ID NCT07466628
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether taking 300 mg of caffeine (about 2-3 cups of coffee) can help healthy young men perform better on muscle strength and thinking tasks in the morning. Fifteen low-caffeine users completed strength exercises and cognitive tests after taking caffeine, a placebo, or no pill. The goal was to see if caffeine can counteract the natural morning dip in performance, which could help athletes who train or compete early.
