NCT ID NCT05316571
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at how interrupting long periods of sitting with short walking or standing breaks affects heart and blood vessel health. Researchers will compare different break schedules in 56 sedentary adults aged 30-60. The goal is to find simple, practical strategies that could eventually lead to public health advice on reducing heart disease risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- walking and standing breaks
- What this could lead to
- If successful, this study could provide clear, simple guidelines on how often to interrupt sitting to improve heart health.
- What could go wrong
- This is a small, early-stage study with only 56 participants, so results may not apply to everyone. It tests short-term effects, not long-term disease prevention.
