Squat Jump Performance and Chiropractic Ankle Manipulation

The goal of this clinical trial is to learn if chiropractic ankle manipulation can improve squat jump performance. It will also learn about the relationship among chiropractic ankle manipulation, ankle range of motion, and squat jump performance. The main questions it aims to answer are: * Does chiropractic ankle manipulation increase squat jump height? * Is there a relationship among chiropractic ankle manipulation, ankle range of motion, and squat jump performance? Researchers will compare squat jump performance between subjects who receive chiropractic ankle manipulations with control subjects to see if ankle chiropractic manipulation works to improve squat jump performance. Participants will: * Visit the research laboratory for one testing session to measure ankle range of motion and squat jump performance, before and after their randomly assigned intervention arm * Receive either a chiropractic ankle manipulations or rest quietly as the control condition during the testing session.
