A Study on the Applications of Open Source Software for Temporal Analysis of Rotational Technique of Shotput


Author(s): Raghvendra Shukla

Abstract: A study on the applications of open source software for temporal analysis of rotational technique of shotput. For the study, ten national level (male/female) shotputters were randomly selected as subject for the purpose of present study. Each shotputters have three trails, and was been recorded with a video camera using 2d methods. Casio Exilim Ex F1H a standard camera which frequency was 300 frame/second and which was placed at 4.50 meter distance perpendicular to the subject in horizontal plane at height of 1.50 meter. Each trail of each subject was analysed thrice independently using open source software, adopting 2d analysis. The variables were selected were total time taken in rotational technique of shotput, total time taken in preparatory phase of technique, total time taken in execution phase of technique (First turn), total time taken in execution phase of technique (Second Turn), total time taken in final phase ( Follow Through). The result presented in table indicate that the calculated mean of total time taken in rotational technique of shotput ranged from 3.52 to 3.89, total time taken in preparatory phase of technique ranged from 1.53 to 1.77, total time taken in execution phase of technique (First turn) ranged from 0.69 to 0.79, total time taken in execution phase of technique (Second Turn) ranged from 0.41 to 0.54, total time taken in final phase ( Follow Through) ranged from 0.62 to 1.24 and the coefficient of varicance among the trail of an individual confirmed the movement elasticity that is consistency (validity) among the trail of an individual performance. The findings reflect that all the athlete selected for the study having consistency. The overall coefficient of varriance among selected athletes was 1%, 8%, 1%, 67% respectively. Mean, S.D, coefficient of variance have been calculated to determine the repeatability of individual video analysis i.e. reliability of adopted software. Further the mean, S.D and coefficient of variance of the trails determined the consistency (validity) among the trial i.e. movement elasticity (validity) of each selected samples. Finally the mean, S.D and coefficient of variance determined of differences (validity) among the athletes in regard to selected temporal variable of rotational technique of the shot.
