Two dimensional analysis of javelin throw with their performance

The motive of the study is to find the most significant effect of selected kinematic variables on the performance of javelin throwers. Total five [N=5], male university level players of Lakshmibai National Institute of Physical Education, Gwalior, who had the good proficiency on the javelin throw. The mean age was 20.4 years. Videography technique was used in order to check the performance of the subjects in performing javelin throw. The Nikon D-3100 camera was used which has frequency of 30 frames per second. The video was taken in the sagittal plane. Three trials were given out of three best performance was selected and the selected phases were taken out from the video by using Kinovea 8.23 software. Through the software, angle of release, angle of wrist joint, angle of elbow joint, angle of shoulder joint, angle of hip joint, angle of knee joint, angle of ankle joint and height of center of gravity, is found out from the photographic sequence. The best performance in javelin throw was used as the criterion measure for the study. The data was analyzed by using multiple regressions to find out the effect of the selected kinematic variables with the performance of javelin throw. Data were taken during the releasing phase of javelin throws.
