A relationship between anthropometrical and kinematical variables of spike jump of intercollegiate level male volleyball players
Abstract:This study was structured to observe whether any relationship exist between anthropometrical and kinematical variables of spike jump of intercollegiate level male volleyball players. For the purpose of the study eight intercollegiate level male volleyball players were selected. The age of the subjects were ranged from 17 to 20 years. Age, height, body weight, arm length and leg length were taken as anthropometric variables. The kinematical variables selected were jump height, range of motion, angular velocity, shoulder joint hyperextension angle and arm swing duration. To obtain data of kinematical variables the selected subject's performances were video recorded. For recording a camcorder operating at a nominal frame of 60Hz and with a shutter speed of 1/2000 second was used. The camcorder was placed on a rigid tripod at the height of 1.5 meters on the right angle i.e. perpendicular to the side-line. It was placed at a distance of 13 meters away from side-line. A setter was used to set the ball for the subjects to spike. Only 3 successful spike jump performance were recorded. The digitization of the obtained data was done with the help of Silicon Coach Pro-7 motion analysis software. The correlation-coefficient was used as tool to establish a relationship between anthropometrical and kinematical variables of spike jump performance. The statistical analysis revealed no significant relationship between variables of spike jump performance of intercollegiate level male volleyball players.
