The purpose of the study was to identify the specific kinematic and kinetic variables associated with a successful fast ball, drop ball, and rise ball using the windmill style softball delivery. The subjects chosen for the investigation were female pitchers who participated in the Women's National Fast-Pitch Softball Tournament held in Buffalo, New York from August 17, 1984 to August 24, 1984.
After analyzing the data obtained from these subjects, the investigator concluded that: (a) there is a great deal of variability between the fast ball pitching mechanics of elite windmill style softball pitchers; (b) the success of a drop ball is dependent upon a small degree of hip and shoulder rotation and a large degree of hip and shoulder closure; and (c) the success of a rise ball is dependent upon a large degree of hip and shoulder rotation and a small degree of hip and shoulder closure.
