A THREE-DIMENSIONAL KINEMATIC ANALYSIS OF THE STAND-AND JUMPSERVE IN FISTBALL
Keywords:fistball, kinematics, serve, segment velocities, segment angle
AbstractThe purposes of the study were a detailed 3D kinematic description of the stand and jump serve in fistball, a comparison of players of different performance levels regarding kinematic parameters and a kinematic comparison of the stand and the jump serve. 19 male fistball players -separated in 3 (stand) respectively 2 Uump) performance based groups -performed a long stand and jump serve. The movements were filmed with two digital cameras (60 Hz) and were analysed using SIMI Motion. The peak velocity of the hip, shoulder, elbow, wrist, fist and ball as well as body angles (shoulder axis, pelvis axis, body torsion and spread angle) and ball parameters were analysed. The results showed significant differences regarding all velocities and ball hitting heights between the groups, but only tendencies concerning the body angles. Thus, peak body segment velocities and -to a certain extent -peak body segment angles during stand and jump serve in fistball were found to be performance limiting factors.
