摘要


射擊運動中,瞄準的穩定性是不可或缺的,同時也是射擊運動的基礎。空氣手槍以立姿無依托的動作對10公尺外的標靶射擊,舉槍的穩定性較差,不可能完全穩定在瞄準點上,因此保持在適當的瞄準區就顯的格外重要。研究目的:一、探討優秀選手與一般選手擊發前之瞄準軌跡參數、擊發後彈著分布、瞄準時間與得分等是否有差異。二、探討受試者擊發前之瞄準軌跡參數、擊發後之彈著分布、瞄準時間分別與得分之相關程度。研究方法:以RIKA Home trainer接收安裝於十公尺空氣手槍上的紅外線瞄準軌跡訊號,輸入電腦後以RIKA Home trainer 2.05版軟體,記錄選手的瞄準軌跡資料;再以JVC攝影機(60Hz)拍攝瞄準軌跡,最後以Kwon3D動作分析軟體將瞄準軌跡資料座標化。結果:得分與標準差方面,兩組達顯著差異;瞄準時間與標準差及彈著分布與標準差,兩組均未達顯著差異。擊發前3秒、前1秒、前0.5秒,優秀選手之在三階段瞄準軌跡參數均小於一般選手。相關分析方面,16名受試者擊發前各階段之瞄準軌跡參數均與得分呈顯著負相關。瞄準時間與得分無關;彈著分布與擊發前各階段之瞄準軌跡參數均與得分呈顯著負相關。結論:優秀選手在擊發瞬間之瞄準軌跡較一般選手靠近標靶中心,所以整體成績優於一般選手。因此保持在正確的瞄準區,尤其是接近擊發瞬間,是得高分的關鍵。

The stability of aiming is one of the most important elements of shooting sport. Purposes: The purposes of this study was to compare the differences between the superior and inferior 10m Air Pistol athletes’ aiming track parameter when they were performing shooting. And explore the correlation between the scores and aiming track parameter before shooting. Methods: Using RIKA Home Air Pistol trainer system to receive the aiming track signal of infrared rays, and to collect the athletes’ aiming track data by the software, RIKA Home trainer 2.05 edition. We used a JVC camera (60Hz) to record the aiming track locus and to digitize the coordinates of the aiming track locus by using Kwon3D motion analysis system. Result: From the results we found that there were significant differences (p<.05) in scores and score standard deviations between the superior and inferior athletes. There were insignificant differences (p>.05) in the duration time of aiming, aiming time standard deviations and pellets distribution and distribution standard deviation. During three seconds, one second and 0.5 second before shooting, the superior athletes’ aiming track shaking displacement was less than inferior athletes’. There was a significant negative correlation (p<.05) between point and aiming track from the sixteen subjects data.. Conclusion: Before shooting, the superior athletes’ aiming track area was smaller than the inferior athletes’. So, to steady or to freeze on the correct aiming area near the shooting moment was the key to gain the high Air Pistol scores.
