Abstract

The purpose of the study was to apply personal counter movement jump (CMJ) ability as a standard of choosing the height of the platform and to analyze the kinematics and kinetics during DJ in order to find the appropriate height of the platform for an individual. Twenty male Division I college volleyball players were the participants. Data were collected using 11 infrared Eagle cameras and two AMTI force platforms. The major finding was that the personalized platform height designed according to personal jumping ability showed significant increase in the impulse of eccentric phase during the drop height being above 100%CMJ. The platform height chosen according to 100%CMJ would be an appropriate height for an individual.
