Effects of Glycerol Hyperhydration on Running Economy in Long-Distance Runners

Iberoamerican Institute of Sports Science and Human Movement·interventional·Posted Feb 10, 2025·Updated Feb 10, 2025

In Brief

A clinical study evaluating The Effect of Glycerol Supplements for Running and Physical Conditioning, Human. Completed, enrolled 30 participants across 1 site.

Detailed Summary

The aim of this study was to evaluate the effects of hyperhydration with glycerol on running economy (RE) in trained runners. The main questions sought to be answered are: 1. Does hyperhydration with glycerol improve running economy? 2. Are there beneficial effects on physical performance? The researchers will conduct a clinical trial with 30 runners (15 men, 15 women) in three sessions. In the first session, VO2peak was determined and running speeds were established for sessions 2 and 3. In the second session, participants performed a stress test. In the second session, participants performed a running test in the euhydrated state under fluid restriction, and in the third session, with glycerol supplementation (22 ml/kg sports drink + 1.2 g/kg glycerol). Variables such as caloric cost unit (CCU), oxygen cost unit (OCU), heart rate (HR), body temperature (BT) and perceived exertion (RPE) were evaluated.
