Abstract

The purpose of this study is to provide teachers and students with scientific basis for effective teeball batting motions by comparing and analyzing foot pressure against the ground caused by weight movements of skilled players who have experiences in playing in the teeball matches and unskilled students who just played during teeball class.

The data of this study were yielded by TPScan V4.3 Triple Pod System of Biomechanics. Inc. SPSS Ver 20.0 was used later for statistics process. T-test was conducted to figure out statistical differences of pressure distribution on the fixed foot between skilled and unskilled players.

The following is the result of this study which measured the overall pressure of the fixed foot and pressure distribution between front part of the fixed foot and back part of the fixed foot of skilled players and unskilled players.

1. According to the analysis on pressure distribution of back part of the fixed foot, there was no difference during ready poses but a meaningful difference was observed at the end of swing motion.

2. According to the analysis on pressure distribution of front part of the fixed foot, both ready poses and swing motion showed a meaningful difference.

3. In terms of pressure ratio of the back part of the fixed foot during batting exercise, no difference was shown during ready poses. However, a meaningful difference was found at the end of swing motions.

4. In terms of pressure ratio of the front part of the fixed foot during batting exercise, there was no difference between skilled players and unskilled players during ready poses but a meaningful difference was showend at the end of swing motions.
