PITCHING A BASEBALL is, to put it mildly, a torturous and self-destructive act. Pitching is the fastest known motion in human biomechanics, the shoulder rotating at the rate of 7,200 degrees per second at its maximum, or the equivalent of 20 full revolutions per second. At the time of the ball’s release, the forces acting on the shoulder are basically equivalent to the pitcher’s body weight; they are akin to someone of similar size trying to yank his arm out of his shoulder socket. Right before release, the pitcher’s elbow straightens at a rate of 2,000 degrees per second, or the equivalent of 5.5 full revolutions per second.
Sounds like my golf swing...
the torturous and self destructive, or the very fast rotation?
