Abstract:
A study on the applications of open source software for two dimensional video analysis of throwing angle of the shot in 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 result presented in table indicate that the calculated mean ranged from 38.66 to 43.55 and the coefficient of variance 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 variance among selected athletes was 32%. In the above table 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 variable throwing angle of the shot. The analysis of throwing angle of the shot have complied the objectives i.e. reliability, movement elasticity, validity and feasibility hence, accepted the drawn hypothesis (The analysis using open source software for 2d analysis of throwing angle of the shot is reliable, the analysis using open source software for 2d analysis of throwing angle of the shot will be high movement elasticity, the analysis using open source software for 2d analysis of throwing angle of the shot will have high validity, the analysis using open source software for 2d analysis of throwing angle of the shot put will have feasibility in regard to selected kinematic variable throwing angle of the shot in regard to the same.
