The purpose of this study is to analyze and compare swing distance, swing speed of better, and appropriate weight of a bat used by a baseball player. I chose five player respectively is A-Group that are sluggers and in B-Group that are control hitters, and made them swing. And their swing forms were taken a photograph by high Sensitive Video Camera, and were digitized by Peak Video Motion Analyzer.
The result of this study is follows.
1. In physical characteristic, the players" physique A-Group is better than B-Group especially in height.
2. A horizontal movement distance, a vertical movement distance, and horizontality-vertically synthetic distance of bat use by A-Group"s players are 1.682m, 1.832m, and 0.704m respectively. And horizontal movement distance, a vertical movement distance, and horizontality-vertically synthetic distance of bat use by B-Group"s players are 1.562m, 1.819m 0.675m. These results showed that A-Group"s players are longer than B-Group"s players in swing distance.
3. The average of swing speed of A bat used by A-Group"s is higher than B-Group"s players. This fact showed that when the players of A and B Group swing the same bat, A-Group"s players swing more rapidly than B-Group"s players.
4. Appropriate weight of the bats used by A and B Group are 890g and 880g each. The speed of ball after impacting with a bat is fastest in case the A-Group"s player used the bat that weighed 890g, and B-Group"s players used the bat weighed 880g.
