Machine vs bodyweight: which hip adductor training builds more strength?
NCT ID NCT07822568
First seen Sep 16, 2026 · Last updated Sep 21, 2026 · Updated 2 times
Summary
Researchers compare two eight-week hip adductor training programs in healthy, recreationally active men. One group trains with a custom isokinetic device that controls the speed of muscle lengthening, while another performs the Copenhagen adduction exercise, a common bodyweight move. A third group does no specific hip adductor training. The trial measures changes in hip adductor strength, muscle thickness, and related physical characteristics to see whether device-based training produces greater adaptations than the bodyweight exercise.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hip adductor strength training, either with an isokinetic device or the Copenhagen adduction exercise
- What this could lead to
- If device-based training builds more strength, athletes and coaches could have a more effective way to lower the risk of groin and hip adductor injuries.
- What could go wrong
- This is a small, short study in healthy active men, so the results may not apply to women, older adults, or people with existing injuries. Strength gains in the lab do not always translate into fewer injuries on the field.
