Optimized beverage formulations for enhanced hydration during exercise
Exploring the impact of exercise intensity and hydration state on beverage preference and fluid intake to optimize flavors that promote healthier hydration and improve post-exercise recovery.
Overview
This research explores the relationship between exercise intensity, hydration status, and beverage preferences to develop beverage formulations that enhance fluid intake and improve post-exercise recovery. The study hypothesizes that optimized beverage flavors with moderate natural sweetness and balanced electrolytes are more preferred and effective compared to plain water or high-sugar/high-sodium options. By aligning beverage compositions with these preferences, the study aims to improve hydration strategies and overall well-being for those engaging in intense or prolonged physical activity.
Technical specifications
The research involves a controlled, crossover trial with 60 healthy adults aged 18-45 years, who will be randomized based on hydration and exercise conditions. Participants will serve as their own control as they experience different hydration states (hydrated vs. dehydrated) and exercise intensities (30%, 50%, and 70% of VO2 max) for durations of 30 to 60 minutes. Beverages tested include optimized formulations with natural sweeteners and balanced electrolytes, plain water, and less preferred options with artificial flavors and high sugar or sodium content. Data collection includes baseline body metrics, continuous monitoring of heart rate, oxygen uptake, lactate levels, cognitive performance, mental fatigue, sensory evaluations, and fluid intake.
Technology readiness level
This research is currently at Technology Readiness Level 2, indicating that the concept has been formulated and experimental proof of concept is underway through controlled trials.
