ANALYSIS OF CORRELATION BETWEEN AIMING ADJUSTMENT TRAJECTORY AND TARGET

Abstract

In archery, there is the relationship among stability of the archer, adjustments made during the aiming procedure, and the targeting coordination. Twelve specialists from the male archery team of National College of Physical Education and Sports took part in this research, with 12 arrows sets up at a distance of 70 m. A laser pen is located on the bow handle for capturing the trajectory of the aiming procedure with a digital video camera, and the other camera for the coordination of target. The Ariel Performance Analysis System motion analysis system is used to obtain the x and y aiming trajectory coordinates for analyzing the correlation. Results of this research were: (1) Ten archers whose variation of the x axis is larger than that of the y axis. (2) There are four archers whose aiming adjustment procedure has all the positive correlation with the target in the x axis, but there are three archers with all negative correlation. (3) In terms of the correlation in the y axis, there are six archers with all positive correlation, but there are two archers with all negative correlation.
