Help For The ACL: Correction Of Poor Landings In Volleyball

More on the ACL

While writing my last blog post on landing mechanics and ACL injuries, I came across a study by Parsons & Alexander that was recently published.  The study attempts to discover if the use of one video coaching session can help to make positive changes in the landing mechanics of volleyball players.  I encourage you to read more about this study on modifying landing mechanics.

Here is a quick summary of the volleyball study:

The researchers took video clips of volleyball players completing a spike jump/landing.  They used Dartfish software to give the girls immediate feedback and also to analyze the results in further detail.  They measured numerous angles related to landing position at ankle, knee, hip, and torso.  The researchers found numerous improvements resulted short term from their video & verbal feedback.  While there were some decreases in the results during the 4 weeks prior to retesting, several of the variables maintained a significantly positive improvement.  Basically, the one feedback session did help the volleyball players to make and maintain positive improvements.

So, what are the take home points?

  1. Video can play a huge role in helping your athletes to make improvements.  Remember that some people are visual learners.  Using video can help them to truly understand what you are saying to them in your verbal coaching.
  2. The athletes were able to maintain some of their improvements over 4 weeks.  What if there was to be more of an emphasis on the changes in landing mechanics?  What if they took 15 minutes a week to focus on them?  What if they received visual feedback multiple times with constant verbal coaching everyday?  I’m sure that the results would be more significant.  As they say, “practice makes perfect”.  What would this do the the number of torn ACL’s in volleyball?  I’m sure it would decrease it dramatically.
