NCT ID NCT06976060
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a 9-week high-intensity interval training (HIIT) program in a community gym for older adults experiencing age-related strength loss. Six participants attended twice-weekly sessions of functional exercises. Researchers measured changes in cardiovascular endurance, balance, strength, and muscle quality. The study was small and completed, so results are preliminary.

- What this could lead to
- If this works, it could show that community-based HIIT classes help older adults improve strength, balance, and endurance.
- What could go wrong
- This is a very small completed study with only 6 participants and no control group, so results may not apply widely. The intervention is exercise, which carries typical risks like injury.
