NCT ID NCT07224659
First seen Jun 27, 2026 · Last updated Aug 20, 2026 · Updated 2 times
Summary
This study will analyze data from over 150,000 people aged 55-74 to see if regular exercise is linked to living longer. Researchers will compare those who exercise at least twice a week with those who rarely exercise. The goal is to better understand how physical activity affects overall and cause-specific death rates in middle-aged and older adults.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could provide stronger evidence that regular exercise helps older adults live longer.
- What could go wrong
- This is an observational study, not a controlled experiment, so it can only show a link, not prove cause and effect. Results may be influenced by other factors like overall health or lifestyle.
