Why one stronger arm may raise injury risk in throwers
NCT ID NCT06302114
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers at Pamukkale University are studying overhead athletes, such as throwers and swimmers, to see whether differences between the dominant and non-dominant arm relate to injury and performance. About 58 athletes aged 15 and older who train and compete regularly take part. Participants complete four physical tests: a medicine ball forward throw, an upper-body Y balance test, shoulder rotation range-of-motion measurements, and rotator muscle strength testing with a dynamometer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a battery of physical tests measuring shoulder range of motion, rotator muscle strength, balance, and medicine ball throw distance
- What this could lead to
- If the tests reveal a clear link between limb asymmetry and injury, coaches and clinicians could use simple sideline measurements to flag athletes at higher risk and tailor training to even out the differences.
- What could go wrong
- This is a small observational study of 58 athletes, so it can show associations but not prove that asymmetry causes injury. Results may not apply to all overhead sports or age groups, and testing only captures a snapshot in time.
