RELATIONSHIP BETWEEN OVER-ARM THROWING PATTERN AND THROWING PERFORMANCE

Abstract

Throwing is a common movement among the upper extremities activities. This study examined the relationship between throwing patterns and throwing distance. Eighty-five age 21 years old students (m =29, F =56)voluntarily participated in the study. Each subject threw a tennis ball as hard as they could straightforward for three trials. A video camera at subjects' right hand side was used to record the subjects' motion. The Burton's (1992) amendment of DSOT table was used to quantify the throwing patterns. Data collected was examined by Pearson correlation(p < .05). The results were as follows: 1. the trunk rotation was found to associated with throwing distance for the male SUbject, 2. the backswing and trunk rotation were associated with throwing distance for the female SUbject.
