What this trial studies
This project investigates the relationship between coffee consumption and exercise performance, focusing on how caffeine metabolism affects athletic capabilities. Healthy elite athletes will participate in a series of controlled experiments where they will refrain from stimulant drinks for 24 hours prior. Each participant will undergo six exercise trials after consuming either decaffeinated coffee, regular coffee, or water, with measurements taken for exercise performance, heart rate, and caffeine levels in urine. The study aims to provide insights into the physiological effects of coffee on high-intensity exercise.
Why it matters
Potential benefit: If successful, this study could enhance athletic performance through optimized caffeine consumption strategies.
How similar studies have gone: Previous studies have shown varying effects of caffeine on exercise performance, but this specific approach focusing on elite athletes is relatively novel.
