　The purpose of this research was to examine the new criteria for observational evaluation of throwing motion for students from 1st to 6th grade elementary school. 570 students (304 boys and 266 girls) participated in this research. We had the performance test of softball throwing. The data was analyzed according to the following four measures: softball throwing distance, throwing motion scores. In addition, we compared the new criteria for observational evaluation of throwing motion with the criterion from previous research.

　　The main results were as follows:

　　1. The new criterion was shown to be reliable, objective and valid for evaluating the series of motions during softball throwing.
　　2. Also in the case of throwing motion the new criterion was shown to be statistically better than previous criterion.
　However, this new criteria is now complicated and isn’t available to many elementary school teachers. So it’ll be necessary to simplify this new criterion, if many elementary school teachers use it to analyze their student’s motion.

　The purpose of this study was to make criteria for observational evaluation of the basic movements on the horizontal bar of first to fourth grade

elementary school children. We evaluated the movements of actual

elementary school children according to these criteria and were able to examine the characteristics of the children’s movements.

　We chose four most basic movements on the horizontal bar of the elementary school.

　1) Inverted hang putting both legs on bar in cross, to front and by bent arms
　2) Front support on bar
　3) Inverted hang putting the region under navel on bar
　4) Inverted hang putting both knees on bar.

　We made these criteria from the viewpoints of overall impressions and various body regions.

　The main results were as follows:

　These criteria were shown to be reliable and objective in overall impressions and various body regions. Furthermore, The data of four basic movements showed almost normal distribution in overall impressions.
