Effects of a High-Sodium, Carbohydrate-Free Multi-Electrolyte Supplement on 15 km Treadmill Time-Trial Performance in Warm and Humid Conditions: A Randomized, Single-Blind, Placebo-Controlled Crossover Trial
Sodium ingestion may support fluid balance and endurance performance in the heat, but most previous studies have used sodium-loading, hyperhydration, or carbohydrate–electrolyte protocols. This study examined the effects of a high-sodium, carbohydrate-free multi-electrolyte supplement (HSES) on 15 km treadmill time-tri...
