The role of the lower half when it comes to the pitching delivery is open to interpretation by many coaches out there, which often serves to confuse the individual athlete. We’ve recently started a long-range analytical project using force plates, EMG sensors, and high-speed video to delve deep into what the lower half is really doing during a high-velocity throw. If you don’t follow me on Twitter (@drivelinebases), then you missed out on a few of our recent findings and data dumps.
Here’s some interesting information from our sports science lab on the lower half:

So you think the right leg contributes big time to velocity? Check closer when EMG activity is highest. Deceleration. pic.twitter.com/XSLpoaUhCY

While this isn’t conclusive, it shows that the trailing leg hamstring and glutes are actually most involved during deceleration and not force production. When you consider that the hamstring flexes the knee, this makes a lot of sense, and that the rear glute extends the […]
