Effect of Excessive Contralateral Trunk Tilt (HS Pitchers)

[Slade-OH]

Interesting. I originally thought they were trying to determine if use of contralateral trunk tilt increases injury risk. Thanks for clearing that up.

Doesn't appear that anything conclusive can be taken away from this particular study but it is an interesting concept. It could perhaps explain why someone with a smaller stature like, say, Tim Lincecum, is able to generate so much velocity. Looking at the pictures below, he seems like a textbook example of contralateral trunk tilt.

Excellent example.

There was a sort of related article in today's New York Times that ponders whether the biomechanical limit to pitching speed has been reached.

At the end of the article there is a brief mention of Mike Marshall (former Cy Young winner and PhD in exercise physiology). He has a system that involves pitchers limiting the lateral arm extension in the pitching motion and throwing "in a straight line as much as possible toward home plate". He claims this increases speed. But it is unclear from the brief mention in the NYT piece how Mike's system relates mechanically to the contralateral trunk tilt tested in the study.

I remember stumbling on a video demonstrating this motion a while ago.
