Abstract

INTRODUCTION: The forceful overarm throwing is considered as one of the fundamental movement for many skills. In addition to this, it is also regards as one of the basic motion of child development for the area of development. There are two ways to study development researches. One is cross-sectional research and the other is logitudinal research. The study adapted Burton’s (1992) amendment of Development Sequences for Overhand Throwing table to measure throwing patterns . In order to realize the change of the throwing distance and related factors that were associated with throwing distance, we tried to trace the developmental trend for a year.
