A common criticism of training using overload/underload implements is that training using weighted balls only trains arm speed, and that such a training method either: Increases the chance of an arm-related injury Doesn’t improve velocity as arm speed is similar across all ages despite differi...
With the recent release of ASMI’s Biomechanical Analysis of Weighted-Ball Exercises for Baseball Pitchers we decided that it was appropriate to discuss its findings in a more in depth review. The first part of this article is going to look at the details of the ASMI study itself. Our commentar...
This article was written by Kyle Boddy, who is the head of the Research and Development department of Driveline Baseball. Kyle designed the study while Michael O’Connell helped collect the data. This is the third of many research themed blog posts where we take a closer look at some of our in-...
This is part two of three of the initial guest posts by Dr. James Buffi. Part one was titled Challenges with Typical Biomechanical Analyses of Pitching. It is impossible to figure out if a specific player scored a run in a baseball game just by looking at the final box score. This is essentially wha...
This is a guest post from Dr. James H. Buffi, Ph.D. in Biomedical Engineering. It is impossible to overstate how excited I am to have Dr. Buffi contribute to our blog in what will be the first article in a three-part series on the biomechanics of pitching. In 2014, Dr. Buffi had a paper published ti...
I’ve been trying to put this article into words for the better part of a year and debated completely shelving it, because frankly, it’s extremely controversial and not accepted by most of the people who train baseball players. However, I am not going to stay silent on the issue any longe...
Two weeks ago, the NY Times published an article titled Young Arms and Curveballs: A Scientific Twist. In the article, Bill Pennington interviewed various experts in the field of youth baseball pitching and got mixed answers. Dr. Fleisig of ASMI said his research can’t prove that curveballs ar...
I’ve been meaning to write on this subject for quite some time, and if it’s received well, I’ll write more about ASMI’s report. A fair warning: This post will be very long and will likely contain a lot of scientific jargon that might be tough to understand. Feel free to conta...
Readers who like a research-specific bent may find my latest postings on the ASMI Message Boards interesting. I am going through a back-and-forth conversation with various people about the relationship between static external rotation (ER) and dynamic maximum external rotation (MER). Miyashita has p...
Tom Verducci has a very interesting article about Stephen Strasburg: Mechanical flaw will be red flag for Strasburg even after return. In it, he says: The answer to why Strasburg blew out — and why his future is a risky one — may lie in his mechanics. Several pitching coaches quietly pre...
