ACL Study: Participants sought

Hello,

You are invited to participate in a biomechanical research study investigating how fatigue effects ACL loading between healthy and ACL-reconstructed males and females. This information will hopefully aid in creating better knee injury prevention programs.

We are particularly interested in recruiting males and females that are healthy as well as those that have experienced an ACL-reconstruction. We ask that you be between the ages of 18 and 30 and are recreationally active. We ask that you are physically active at least 3 days per week for a minimum of 30 minutes each session. We also ask that you not have any lower back or leg injuries within the past six months prior to testing.

This study will involve completing a weight-bearing ankle joint range of motion assessment, a knee joint laxity assessment, a single-leg balance assessment, and a muscle strength assessment of your hip, knee, and ankle muscles. We will also involve motion capture to assess your leg mechanics during landing pre and post an exercise protocol aimed to make you tired. For the motion capture testing, you will perform three tasks. For task 1, you will perform a bilateral box jump from a height of 30-cm, followed by a maximum vertical jump immediately after you land; for task 2, you will jump off of a 30-cm box onto your right foot and make a sidecut move to the left; and for task 3, you will jump off of a 30-cm box onto your left foot and make a sidecut move to the right.

The current study will require you to come into the Biomechanics/Sports Medicine Lab for two sessions, which will last approximately two and a half hours each. If you feel you fit the criteria for this study and are willing to participant, please contact the research investigators Dr. Joshua Weinhandl (jweinhan@utk.edu), Shelby Peel (speel@vols.utk.edu), Jake Melaro (jmelaro@vols.utk.edu), or Lauren Schroeder (lschroe1@vols.utk.edu) via email or telephone (865) 974-2091 (office number).

Thank you for your time,
