摘要

射箭講求穩定性，射手從伸展至放箭的過程中需不斷的保持穩定及平衡才能讓箭安穩的往靶心中間飛過去，以達到命中滿分十分的優異成績表現。本研究目的欲分析探究穿著足弓支撐鞋墊對複合弓選手在30 m距離進行瞄靶射箭時，對運動表現和肩關節穩定性的影響。招募15名大專校院射箭隊的優秀複合弓選手為受試者，檢測分成前、後測驗，受試者需穿著足弓支撐鞋墊適應4週後再進行後側。使用加速度感測器來測量右手拉弓手肩關節處的三軸加速度，以射箭平均箭值之得分數為受試者運動表現之數據，以分析受試者穿著平版鞋墊與足弓支撐鞋墊時射箭，在肩關節穩定性及運動表現的差異。本研究結果發現：一、複合弓選手穿著足弓支撐鞋墊比穿著平版鞋墊顯著的提高得分箭值。二、複合弓選手穿著足弓支撐鞋墊可減少右肩峰X軸方向之加速度。三、右肩峰Z軸方向之加速度與射箭得分呈現負相關。本研究結論為複合弓選手在穿著足弓支撐鞋墊的放箭過程中，能有助於增加得分箭值和提高上肢前後方向（X軸）穩定性，代表箭著點的集中性有增加的趨勢。而得分與Z軸呈現負相關係，表示右肩關節向下之加速度是減少的趨勢，推論出穿著足弓支撐鞋墊後拉弓手放箭出手時穩定性會較高。然而，穩定性的提高可能有助於增加箭著點的密集度，並間接影響到得分箭值，且對於射箭選手訓練上具有實用性之價值。

Archery emphasizes the stability of an individual. The archer needs to maintain stability and balance from the stretch to the arrow which enable arrow to fly toward the center of the bullseye in order to achieve an excellent score performance. The purpose of this study was to analyze and investigate the effect of arch support insoles on the performance and stability of the shoulder joint of compound archers when shooting at a target distance of 30 m. Fifteen elite compound archers from college archery teams were recruited as subjects. The test was divided into front and back tests. Subjects wore arch support insoles to adapt to the back after 4 weeks. The acceleration sensor was used to measure the triaxial acceleration at the shoulder joint of the right hand of archer. The average arrow score value of the archery was used as data of the athletic performance, and the differences in shoulder joint stability and athletic performance of subjects shooting archery insoles and arch support insoles were analyzed. The results of this study showed that: (1) Wearing arch support insoles significantly improved the score of the average arrow value compared to wearing flat insoles. (2) Wearing arch support insoles reduced the acceleration of X-axis of the right acromion. (3) There was a negative correlation between the acceleration of Z-axis of the right acromion and score of arrow value of the archery. Our findings conclude that wearing arch support insole can increase the scoring arrow value, and improve the stability of the front and rear direction (X-axis) of the upper limbs during the arrow release process. The score has a negative relationship with the Z-axis, which indicates decreased downward acceleration of the right shoulder joint. It is inferred that the stability of the archer can be greater when archer releases the arrow after wearing the arch support insole. Increasing stability may increase the density of arrow strikes, indirectly affect the value of scoring arrows, and has practical value for archery training.
