Official title
The Effects of Chiropractic Ankle Manipulation on Athletic Performance of College-Aged Recreational Athletes: Randomized Controlled Trial
Overview
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.
Interventions
- Other Manual Therapy Procedure: Chiropractic Ankle Manipulation
The lower extremity manipulation (LEM) procedure is a short lever, high velocity, low-amplitude distractive (caudal) thrust directed at the talocrural joint. The treating chiropractor will deliver the LEM to the right ankle then the left ankle. LEM is an adjustment for long axis distraction of the tibiotalar joint with the goal to improve dorsiflexion of the ankle joint.
Primary outcome measures
- Squat Jump Height [Time frame: Baseline on Day 1 to Immediately after Intervention on Day 1]
- Range of Motion of Ankle Dorsiflexion [Time frame: Baseline on Day 1 to Immediately after Treatment on Day 1 and at End of Test Session on Day 1]
Secondary outcome measures (3)
- Leg Muscle Power (W/Kg) [Time frame: Baseline on Day 1 to Immediately after Intervention on Day 1]
- Contraction Velocity of Leg Muscles (mm/s), Force-Velocity Curve [Time frame: Baseline on Day 1 to Immediately after Intervention on Day 1]
- Rate of Force Development of Leg Muscles (N/s), Slope of the Force - Velocity Curve [Time frame: Baseline on Day 1 to Immediately after Intervention on Day 1]
