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.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 18-40 who are elite athletes.

Not a fit: Patients with conditions such as diabetes, hypertension, or other specified health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance athletic performance through optimized caffeine consumption strategies.

How similar studies have performed: Previous studies have shown varying effects of caffeine on exercise performance, but this specific approach focusing on elite athletes is relatively novel.
