Exercise as medicine? new study tests High-Intensity workouts for rheumatoid arthritis
NCT ID NCT05768165
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether a 12-week program of high-intensity interval exercise can improve heart function, reduce inflammation, and boost quality of life in people with rheumatoid arthritis. 87 adults with stable, low-to-moderate disease activity will take part. The program includes supervised aerobic and resistance training twice a week, plus one optional session on their own.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- high-intensity interval exercise
- What this could lead to
- If it works, this could point toward a safe, drug-free way to improve heart health and reduce inflammation in people with rheumatoid arthritis.
- What could go wrong
- This is a small, early-stage study with only 87 participants, so results may not apply to everyone. Exercise may be hard to sustain long-term, and benefits might be modest.
