Deuterium-labelled glucose reveals how athletes burn fuel at different intensities
NCT ID NCT07646665
First seen Jun 27, 2026 · Last updated Jul 09, 2026 · Updated 2 times
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.
