Deuterium-labelled glucose reveals how athletes burn fuel at different intensities
NCT ID NCT07646665
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses a special type of glucose labelled with deuterium (a safe, non-radioactive tracer) to track exactly how much sugar from a drink the body burns during cycling. Six endurance-trained adults will exercise at both moderate and high intensity while researchers measure the rate of carbohydrate oxidation. The goal is to understand how exercise intensity affects the body's ability to use fuel from an external source.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
deuterium-labelled glucose
What this could lead to
If successful, this could help athletes and coaches fine-tune fueling strategies for different exercise intensities.
What could go wrong
This is a very small, early-stage metabolic study with only 6 participants, so results may not apply to all athletes or exercise conditions.
