Abstract

The purpose of this study was to investigate biomechanical factors associated with successful overhand floater serves. Specifically, the study investigated the kinematics of the server at ball-hand contact. Six subjects performed floater serves for this investigation. Subjects served three trials under each of the following conditions: (a) short and long serves and (b) three ball-valve positions at ball-hand contact. Threedimensional cinematographic methods were used to obtain the data. Descriptive statistics were utilized to compare floater and nonfloater serves with respect to distance and ball-valve position. The results showed that (a) more long serves were classified as floater compared to short serves; (b) long serves were associated with greater linear displacement, linear velocity, and angular velocity at ball-hand contact compared to short serves; and (c) few posture differences were evident in the serving arm of subjects serving floater and nonfloater serves, or long and short serves.
