Kinematic Analysis of the Final Release position of elite Archer

The purpose of the study was kinematical analysis of an Elite archers. In present study total sample five Indian International level male Recurve category Archers was selected by Purposive sampling technique from SAI Archery training Center Sonipat. The age of the subjects was between 24 (± 5) years, hight of the subjects 6.0` (± 5 Inch), participation year between 2016-2022, shooting FITA score between 650-720 in archery was selected as a subjects for the study. According to Casio EX-F1 high speed camera was used, which have frequency from 60-300 frames per second (f/s).  The data were recorded from Superior view, Lateral view, Anterior view and Medial view. The distance between shooting line and target is 70 meter. Shooting line is passed horizontally through the Center of Gravity box, Center of Gravity box is a square box drown with the measurement of 1×1 m, Center of Gravity box is equally divided into 4 parts. A straight line is passed vertically on it and a horizontal line which is shooting line and is drawn 70 meter apart from the target. The distance between bull eye of the target and the floor surface is 5 feet. Siliconcoach Pro8 update motion analysis software and Tracker motion analysis software was used for kinematical analysis of at the time of final release position in archery. Descriptive statistic was used. To find out multi correlation between dependent variable performance on target 1-10 (bull eye) in points and independent variables (selected linear variables). The significant correlation was found between Height of body Center of Mass, Height of body Center of Gravity, Height of Projectile and obtained value (-.893), (.878), (-.945) is greater than tabulated value of (.878) therefore it shows significant relationship of this independent variable with performance in archery. Whereas, in case of Body force aliment right medial, Body force aliment left medial the obtained values (.360) and (.770) are lower than tabulated value of (.878) therefore it shows insignificant relationship of these independent variable with performance in archery. The significant correlations with height variables suggest that certain aspects of an archer's body positioning, such as the height of the center of mass, center of gravity, and projectile, play a crucial role in archery performance. The negative correlation with the height of the center of mass implies that a lower center of mass is associated with better performance. The insignificant correlations with body forced alignment variables suggest that, at least within the parameters measured, the lateral alignment of the body (right and left medial) does not significantly influence performance in archery. Since the significant relationship was found between Height of body Center of Mass and Height of body Center of Gravity, Height of Projectile and Body force aliment left medial of the subject among independent variables as calculated “r” (-.960), (.887), (-.959) is found greater than the required tabulated value of (.878) at .05 level of significance. In case be seen the significant relationship was found between Height of body Center of Gravity and Body force aliment left medial of the subject among independent variables as calculated “r” (.935), is found greater than the required tabulated value of (.878) at .05 level of significance. The strong correlations among these variables indicate a close relationship between the height-related kinematic variables (center of mass, center of gravity, and projectile) and the lateral alignment of the body (body forced alignment left medial). The negative correlations suggest that as the height of the center of mass decreases, the height of the center of gravity and the height of the projectile tend to decrease, and as the height of the projectile decreases, the body forced alignment left medial tends to increase. The study concludes that there is a statistically significant and positive relationship between the height of the center of gravity and body forced alignment on the left medial side in archery. This finding implies that variations in the height of the center of gravity are associated with corresponding changes in the lateral alignment of the body, specifically towards the left medial side.
