Sitting less + exercise may double heart benefits for desk workers
NCT ID NCT07363499
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether adding less sitting time to regular exercise improves heart and metabolic health more than exercise alone. About 30 adults with desk jobs who sit over 9 hours a day will either follow an exercise plan or do the same exercise plus reduce sitting. Researchers will measure insulin sensitivity, blood fats, and other health markers to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Physical activity plan and reduced sitting time
- What this could lead to
- If it works, this could point toward simple lifestyle advice to help prevent heart disease and diabetes in people with desk jobs.
- What could go wrong
- This is a small, early-phase study with only 30 participants, so results may not apply to everyone. It also relies on people sticking to the program, which can be hard in real life.
