Breaking Into Softball Baseball and softball are similar in some ways but very different in others. Nothing is more evident than the pitching delivery between overhand and underhand. When you look at the movements between both deliveries, softball deliveries start with the toes pointed toward home plate, opposed to baseball pitchers who have their toes oriented at 90 degrees in home plate’s direction. You need to look no further from the drive foot to see how the kinetic chain differs between two deliveries; however, they both end up in the same position with the pelvis, trunk, and shoulders facing forward. In softball, one impressive thing is that the pitchers are airborne for a brief instant in their deliveries, which is a prime feature of the direction of triple extension at the ankle, knee, and hip directed right in line with the target. In baseball pitching, triple extension occurs in the frontal plane (plane of movement we see from the inside of the delivery that splits the body in front and back halves). The energy produced into foot contact is, in a sense, laterally directed. I have studied momentum profiles in pitchers, but my gut is that softball pitching momentum linearly is much higher than baseball (along the sagittal plane), but rotational momentum (along the transverse plane) is likely higher in baseball pitchers. |
