Scientists aim to find the perfect dose of resistance exercise for heart health
NCT ID NCT06619444
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study looks at how different amounts of resistance exercise (like weight lifting) affect heart health in overweight, inactive adults. Participants are split into groups that do aerobic exercise alone or aerobic plus varying durations of resistance training. The goal is to determine the minimum, optimal, and maximum effective dose of resistance exercise for preventing cardiovascular disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- resistance exercise
- What this could lead to
- If successful, this could provide clear guidelines on how much resistance exercise is needed to prevent heart disease, helping millions improve their health.
- What could go wrong
- This is a behavioral study, not a drug trial, so results depend on participant adherence. The findings may not apply to people who are already active or normal weight.
