Exercise order may boost heart function in heart failure patients
NCT ID NCT06626542
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether doing resistance or aerobic exercise first during a rehab session affects heart function in men with chronic heart failure. Sixty men aged 55-65 with reduced heart pumping ability took part. Researchers measured heart function and quality of life to see if the sequence made a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- resistance and aerobic training exercises
- What this could lead to
- If the sequence matters, it could help design better cardiac rehab programs to improve heart function and quality of life in heart failure patients.
- What could go wrong
- This is a small, completed study with only 60 male participants, so results may not apply to women or all heart failure patients. The exercise order may not produce a clear benefit.
