Kinematic Analysis Forearm Passing in Volleyball at Different Distances

Abstract

The main goal of this study is to determine which of the applied kinematic parameters best predictor of accuracy in passing forearm. At the same time we want to establish the differences in the variables applied during the execution of the lower forearm pass to smaller and further away . The sample for this study is a 31 years old student of II study and cycle studies at the Faculty of Physical and sport of the University. All subjects were male average age of 21.66 ± 1.58 , average body height 180.37 ± 9.00 and an average weight of 76.43 ± 14.25. The video camera Casio Exilim EX-F1 was used for filming. The subjects were five times performed the technique on a smaller and five times farther away. To calibrate the space was used for calibration frame 1m x 1m x 2m. The camera was working at a frequency of 300 Hz resolution 720 x 576. The data was processed using a Kinovea software. On the basis of applied statistical analysis we can say that on the basis of certain kinematic parameters can make the prediction results in criteri variables in both groups. Also, it was found that there were statistically significant differences in the observed kinematic parameters between groups "Closer" and the group "Farther", and these differences are significance at the level .01 and .05. Consequently , our study is focused in order to obtain relevatinih information that will contribute to the understanding of the mechanical characteristics of the movement which ultimately contributes to more efficient training process . The results of our study indicate differences in kinemti?kim parameters when performing techniques of the lower forearm pass but in relation to the different position of the target. For faster and more efficient process of training the lower forearm passing volleyball, very important is the optimization of the angles of individual body segments as well as the defining characteristic of a breach during the execution of technical elements. This study allows us to obtain information that is relevant to the faster and more successful training techniques lower forearm passing.
