Summary

This study tested how different amounts of caffeine from coffee affect muscle endurance, sprinting, and thinking in 69 physically active men and women. Participants were grouped by their usual daily caffeine intake (low, moderate, or high). They performed exercises and cognitive tests after drinking decaf or caffeinated coffee with varying doses. The goal was to see if a person's habitual caffeine use changes how well caffeine boosts performance.
