What this trial studies

This study investigates the impact of a caffeinated electrolyte-glucose drink on endurance, strength, and cognitive performance in trained cyclists. Participants will undergo a series of trials involving cycling in a warm environment, followed by assessments of strength and cognition. The study employs a repeated-measures, cross-over design with four different drink conditions, including a caffeinated drink and water. Data on cycling performance, hydration status, and physiological responses will be collected throughout the trials.

Who should consider this trial

Good fit: Ideal candidates are healthy, active cyclists aged 18-55 who train at least three times a week.

Not a fit: Patients with a history of caffeine sensitivity or certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance athletic performance and hydration strategies for active individuals.

How similar studies have performed: Previous studies have shown positive effects of caffeine on performance, but the combination with electrolytes and carbohydrates in this specific formulation is relatively novel.
