The Relationship of Selected Biomechanical Variables with the Performance in Javelin Throw

Abstract

The aim of the study is to assess the relationship between selected biomechanical variables with the performance in Javelin throw.  Five male Javelin throwers of Lakshmibai National University of Physical Education, Gwalior from the track & field match practice group were selected as the subject for the present study. Their age was between 17 to 25 years. The sequential photography technique was employed to record the technique of javelin throwers. A Motor driven, Nikon D-40 camera was used. The subjects were photographed at stance position and release moment in sagittal plane. From the photographs, the stick figures were prepared by using Joint-point Method, and various biomechanical variables were obtained at the moment of releasing the javelin, suggested by Hay. Pearson’s product moment correlation was used to find out the relationship of selected biomechanical Variables with the performance of male Javelin throwers. The level of significance was tested at .05. The angle right and left ankle joint and left elbow joint have exhibited significant relationships at stance position and In case of release moment shoulder joint (right) and elbow joint (left) have shown significant relationship with the performance of subject. The result of the height of C.G. at selected moments has insignificant relationship with the performance of subject at stance position and at release moment. Training focusing on Right knee, ankle, hip and shoulder joint is recommended.
