No results posted yet for this study

Summary

Caffeine is known to enhance physical and mental performance, but few beverages combine caffeine with electrolytes and carbohydrates to enhance exercise performance. This study evaluates a caffeinated electrolyte-glucose drink's effect on endurance, strength, and cognition. Using a repeated-measures, cross-over design, 20 trained cyclists will complete one familiarization and four randomized 3-hour experimental trials (Liquid I.V.™ Energy Multiplier, Hydration Multiplier, Sugar-Free Hydration Multiplier, and water). Each trial includes 2 hours of cycling in a warm environment (32ºC), followed by strength and cognitive assessments. Cycling performance, capillary blood, urine, and expiratory gases will be collected.
