摘要

目的：本研究旨在探討優秀射箭選手引弓動作相關肌群張力及硬度在測驗過程各階段張力與硬度的特性。方法：對象主要以國立台灣體育運動大學、國立體育大學及特力射箭隊男女計17名為受測對象。每位選手均接受70公尺雙局的模擬比賽程序進行測驗，並從射箭過程記錄受試者在熱身前、熱身45分鐘、測驗前、測驗18箭時、測驗36箭時、測驗54箭時及測驗72箭時左斜方肌、右斜方肌、伸腕肌及屈指肌的肌肉張力及硬度，並以相關量化資料進行無母數統計之弗里曼單因子等級變異數分析，比較引弓動作各相關肌群張力及硬度在各階段的肌肉特性分析。結果：優秀射箭選手引弓動作相關肌群在熱身後肌肉張力及硬度下降。優秀女子射箭選手引弓動作相關肌群在測驗過程中各階段肌肉張力及硬度並不會隨著測驗過程顯著變化。優秀男子射箭選手引弓動作相關肌群在測驗過程中各階段肌肉張力及硬度會隨著測驗過程顯著變化。結論：優秀射箭選手引弓動作相關肌群在熱身後，降低肌肉的張力與硬度。此外，測驗過程中在不同階段的肌肉張力與硬度亦多未呈現明顯變化。該發現可能由於優秀射箭選手有較佳的肌力，以維持較穩定的射箭表現。

Purpose: The purpose of this research was to study the relationship of drawing to release associated muscular groups in muscle tension and muscle stiffness in 70 meter double rounds of various periods for elite archery athletes. Methods: Subjects were composed of 17 male and female from National Taiwan University of Physical Education and Sports, National Taiwan Sports University, and B&Q archery team. Data of Left trapezius, Right trapezius , wrist extensors and wrist flexors was assessed by myotonometer (MYOTON-3) for each athlete was collected in the periods of pre warm-up, after warm-up 45 minutes, pre-test, test after the 18th arrow, test after the 36th arrow, test after the 54th arrow, and test after the 72nd arrow in 70 meter double rounds simulated competition. Quantitative data analysis was performed with non-parametric Friedman one-way analysis of variance by ranks. Results: This research showed that the muscle tension and muscle stiffness reduce after warm-up in associated muscular groups. The muscle tension and muscle stiffness has no significantly different in elite female archer during 70 meters double rounds. The muscle stiffness are significant difference in elite male archer during 70 meter double rounds. Conclusion: The elite athlete have reduction of muscle tension and muscle stiffness on main muscle group for archery performance after warm-up. The muscle tension and muscle stiffness have not changed during whole testing processes. The findings suggest that elite archers might have better muscle strength and maintain stable performance.
