ACL Strong Research Study

With knees being the most frequently injured body part in skiing, and a factor causing many to give up the sport earlier than planned, we owe it to the industry to figure out how to preserve knees and keep skiers and riders on the mountain for as long as possible.

ACL Strong utilizes neuromuscular training concepts and simple at-home exercises to help skiers and riders reduce the chance of knee injuries and perform better on the snow.

After 3 successful seasons with our ski area program, we are launching a formal research study with the support of NSAA to assess the effectiveness of ACL STRONG on reducing injuries, particularly ACL (knee ligament) injuries, among ski area employees.

Organizations who Trust ACL Strong

ACL Strong was Designed for Ski Area Employees, with Instructors, Patrollers, and On-Snow Staff in mind...

We plan to begin the Research Study in January 2021!

We are looking for volunteers to participate in the study in one of two groups. The "intervention" group will complete the ACL Strong training. The "control" group will NOT complete the training, but will be paired (virtually) with a member from the intervention group. Both groups will answer basic questions throughout the season. (more info coming soon)

ACL Strong is endorsed by the Professional Ski Instructors of America & American Association of Snowboard Instructors (PSIA-AASI) and is approved for 2.0 CEUs.  PSIA-AASI members may submit their certificate to PSIA-AASI to attain their credits.
