Summary

This study tests whether a chiropractic ankle adjustment can improve how high recreational athletes can jump. Sixty college-aged athletes who exercise regularly will either receive the ankle manipulation or rest quietly. Researchers will measure jump height and ankle flexibility before and after to see if the adjustment makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Chiropractic ankle manipulation (a quick, controlled thrust to the ankle joint)
What this could lead to: If it works, this could point toward a simple, drug-free way to boost athletic performance like jumping.
What could go wrong: This is a small, early-stage trial with only 60 people. The effect may be small or not apply to serious athletes. There is a small risk of minor soreness from the manipulation.
