@Trip Yes you are correct. The statement that sidearm pitchers are “more susceptible to reduced elbow valgus torque” is contradictory and confusing because it is wrong. It was a typo in the original abstract that was later corrected (it is actually “higher” not “reduced”). Here’s a link to updated one:

The papers that I have read by Aguinaldo have been very poorly written. I am not familiar with the one you’re referencing, but I suspect it follows the trend of his other publications. He did/does have a large grant from MLB, however, so he must, at least, be persuasive enough to convince the powers that be to give him some money.

I haven’t actually read the abstract; that is a bit confusing. The study does make it a lot more clear. This is yet another reason why reading abstracts is not a substitute for actually reading the research paper.

I would love to read the entire article (Correlation of Throwing Mechanics With Elbow Valgus Load in Adult Baseball Pitchers by Aguinaldo et al.) because the abstract is a mess.

For example, here are two quotes from it that seem to contradict each other:
-”Fourteen pitchers displayed a sidearm delivery and had significantly higher elbow valgus torques than did those with an overhand arm slot position.”
-”Sidearm pitchers appeared to be more susceptible than overhand pitchers to reduced elbow valgus torque.”

What does “susceptible to reduced elbow valgus torque” mean in the context of this study?

[...] mechanics make it safer to throw a baseball (an extremely un-natural & violent motion), but this is way over my head. Anybody ever play any of the Commander Keen games? How about the original Duke Nukem? I only just [...]
