空氣手槍選手瞄準期與準備擊發期之瞄準軌跡特徵與成績之分析

空氣手槍以立姿無依托的動作對10公尺外的標靶射擊，在實際的射擊中，由於舉槍的穩定性較差，射手的槍總是在晃動的，射手的瞄準線也是圍繞著靶心不停的在變化，因此保持在適當的瞄準區就顯的格外重要。研究目的：探討優秀選手與一般選手在瞄準期與準備擊發期之瞄準軌跡參數特徵。方法：以RIKA Home trainer為主要研究工具，以Kwon3D動作分析軟體將資料座標化。結果：優秀選手與一般選手在瞄準期與準備擊發期之平均瞄準點至圓心距離、瞄準軌跡面積、最大水平偏移量有顯著差異；瞄準軌跡長度與最大垂直偏移量無差異。結論：瞄準的晃動範圍大小，表示選手瞄準能力的穩定性，此為獲取高分的重要關鍵，優秀選手在瞄準期與準備擊發期間控制槍穏、找到瞄區等之能力均優於一般選手，因此得分較高。

In shooting sport, the stability of aiming is an inevitable element, and it also is a basis of shooting sport. Using the air pistol without any dependence by the pose of standing to shoot the target which is 10m outside affects the stability weaker while raising the pistol. It is impossible to aim the aiming point totally stable. Hence, to keep in the proper aiming area is extraordinarily important. Purposes: To explore is there any difference between the superior athletes' and inferior athletes' aiming track parameter before shooting. Methods: Using RIKA Home trainer and Kwon3D software to coordinate the data. Result: The superior and inferior athletes' having obviously differences in aiming track and average distance of aiming point, average distance of aiming point and the distance of the center of circle and the area of aiming track and the highest of horizontal offset. Both of them had not obviously in aiming track's distance and the highest of vertical offset. Conclusion: The size of shaking range while aiming indicated the athlete's stability of aiming ability, and it was the key to gain high scores. The superior athletes' control air pistol and find the area of aiming ability during the time in aiming and prepare shooting are better than inferior athletes'. So, the superior athletes gain high scores.
