Kinematic Comparison of Different Technique of Putting the Shot at the Moment of Release

Abstract

The purpose of the study was to conduct a kinematic comparison of different techniques of putting the shot at the moment of Release. Eight male shot putters of L.N.U.P.E. between the age group of 20 to 26 years, who had been participating regularly, were selected as subjects. 2 D Kinovea Video Anlysis software was used for kinematical analysis of different techniques of putting the shot. Casio Exilim Ex F1H a standard camera which frequency was 300 frame/second and which was placed at 4.67 meter distance perpendicular to  the subject in horizontal plane at height of 1.50 meter.  To find out kinematical comparison between those shot putters who uses different stances t-test was used. For testing the hypothesis the level of significance was set at .05.Results show that the calculated t value is 1.237   and      .260   in relation to linear kinematical variables at moment of releases i.e. Height of c.g. of subject and height of c.g. of shot respectively. It also show that calculated t value for angular kinematic variables such as ankle (right & left),knee(right&left),hip(right&left),shoulder(right&left),elbow(right&left)andwristjoint(right&left)is(.454&2.83*),(1.39&.351),(2.23&1.51),(.290&.419),(.550&.794)and(.365&.833). 1)Insignificant difference was found between those shot putters who uses different technique of putting the shot in relation to  height of c.g. of subject and height of c.g. of shot put.2)Insignificant difference was also found in relation to ankle (right), knee (right & left) and hip joint (right), shoulder (right & left), elbow (right & left) and wrist joint (right & left).3)Significant difference was found between those shot putters who use different technique of putting the shot in relation to ankle joint (left).
