Grunt = Velo - Grunting added 2.7 mph velocity for college pitchers

Grunting added 2.7 mph compared to non-grunting for D3 college pitchers!

There’s also some research on grunting for improving tennis serve speed.

If it works for throwing and serving, why not hitting?? 


Summary:

The document is a research article titled "The effect of grunting on overhead throwing velocity in collegiate baseball pitchers" published in the International Journal of Sports Science & Coaching. The purpose of the study was to determine the effect of grunting on overhead throwing velocity in collegiate baseball pitchers. Twenty-four division III collegiate baseball pitchers participated in the study and were asked to replicate the technique of grunting during their throws. Throwing velocities were measured with a radar gun. The results showed that throwing velocity was significantly higher during the grunting trials than the non-grunting trials. Age, height, weight, and handedness had no impact on the effect of grunting on throwing velocity. The authors suggest that grunting offers a simple and immediate means of enhancing throwing velocity in collegiate baseball pitchers, and more research is needed to determine the effects in populations of different skill levels.
