Intervention: Caffeinated Beverage with Carbohydrates and Electrolytes (CAF+CE, Liquid I.V. Energy), Caffeinated Beverage with Electrolytes (CAF+E, Prime Energy), Caffeinated Beverage (CAF, Celsius) or water. All participants (n = 28) completed the three active arms (CAF+CE, CAF+E and CAF) and the water arm of the protocol.
Study Duration: Four 250 mL aliquots administered over 30 min; urine collected at four hours.
Eligibility Criteria:
- Healthy adults (14 men, 14 women).
METHODS
Here is how the tested drinks compare in terms of caffeine, electrolytes and carbohydrates:
Key Findings
1.
At the 240-minute (4-hour) timepoint, the Beverage Hydration Index (BHI) for CAF and CAF+E was significantly lower than CAF+CE (P<0.05) and water (P < 0.05).
2.
Urine mass for CAF and CAF+E was significantly greater (by 244 g and 162 g respectively) relative to CAF+CE (P < 0.01).
3.
CAF+CE outperformed CAF+E and CAF on net fluid balance, with significantly greater water loss observed from the 90-minute timepoint onwards in the CAF+E and CAF groups compared to CAF+CE and water (P < 0.05).
