Can stronger ankles change how you walk?
NCT ID NCT07820449
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers at the University of Ljubljana studied whether a 12-week ankle strength training program changes muscle strength and walking mechanics in healthy, active men aged 18 to 50. Participants trained on a device that isolates the muscles that turn the foot outward and inward, starting with eight weeks of muscle-building work followed by four weeks focused on nerve activation. The team measured ankle torque, electrical activity in six lower-leg muscles, and walking speed across three walking conditions. The study enrolled 32 men with no recent ankle injury.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 12-week ankle evertor and invertor strength training program on a specially designed device
- What this could lead to
- If the training builds ankle strength and changes walking mechanics, it could inform exercise programs aimed at lowering ankle sprain risk in active people.
- What could go wrong
- This is a small study of 32 healthy, recreationally active men, so results may not apply to women, older adults, or people with existing ankle problems. Strength gains in a lab may not translate into fewer injuries.
