反曲弓競技用箭桿精度差異性分析
Analysis of the Difference in the Accuracy of the Shaft in the Recurve Bow Competition
摘要
目的：探討反曲弓競技用箭桿，以不同材質（價位）分類，比較精度相關參數之差異情形提供訓練及競賽參考依據。方法：利用Fivics射箭器材公司所製造箭桿檢測儀（Fivics-FIV161）測4種競技用不同材質（價位）箭桿之精度參數，包含箭桿不同接觸面之撓度（Arrow spine）、箭桿直度（Straightness）以及使用微量電子秤（Lichen-JT3003D）檢測箭桿重量公差（Weight Tolerance），並以單因子變異分析（One-way ANOVA）分析不同箭桿之差異，及利用變異係數（Coefficient of Variation）了解不同箭桿重量誤差情形。結果：箭桿材質對於箭桿直度達顯著差異（p<.01），X10 碳鋁箭＜A/C/E碳鋁箭＜X7鋁箭＜Apollo碳箭；箭桿材質對於箭桿撓度達顯著差異（p<.05），X7鋁箭＜X10碳鋁箭＜A/C/E碳鋁箭＜Apollo碳箭；箭桿重量變異係數A/C/E碳鋁箭＜Apollo碳箭＜X10碳鋁箭＜X7鋁箭。結論：材質（價位）不是影響箭桿不同接觸面撓度主要因素，但相同材質不同價位（碳鋁箭）會因價位較高有較佳的撓度一致性表現。箭桿直度會受到材質（價位）的影響，高單價之箭桿直度較佳。箭桿重量一致性不是影響售價主要因素，A/C/E碳鋁箭為最優，次之Apollo碳箭，再者為X10碳鋁箭，最後X7鋁箭為最差。

Purpose: To discuss the competitive arrow shafts for recurve bows, classify them according to different materials (prices), and compare the differences in accuracy-related parameters to provide a reference for training and competition. Methods: Using the arrow shaft detector manufactured by Fivics Archery Equipment (Fivics-FIV16) to detect the accuracy parameters of 4 kinds of arrow shafts with different materials (prices) for competition, including the deflection of different contact surfaces of the arrow shaft (Arrow spine), the straightness of the arrow shaft (Straightness) and The weight tolerance of the arrow shaft was detected by a micro-scale electronic scale (Lichen-JT3003D), and the difference between different arrow shafts was analyzed by one-way ANOVA, and the weight error of different arrow shafts was understood by using the coefficient of variation (Coefficient of Variation). Results: The shaft material had a significant difference (p<.01) for the straightness of the shaft (X10 carbon aluminum arrow < A/C/E carbon aluminum arrow < X7 aluminum arrow < Apollo carbon arrow); Reach significant difference (p<.05) (X7 aluminum arrow < X10 carbon aluminum arrow < A/C/E carbon aluminum arrow < Apollo carbon arrow); shaft weight variation coefficient A/C/E carbon aluminum arrow < Apollo carbon arrow < X10 Carbon Aluminum Arrows < X7 Aluminum Arrows. Conclusion: Material (price) is not the main factor affecting the deflection of different contact surfaces of the arrow shaft, but the same material at different prices (carbon-aluminum arrows) will have better deflection consistency due to higher prices. The straightness of the shaft will be affected by the material (price), and the straightness of the shaft with a high unit price is better. The consistency of the shaft weight is not the main factor affecting the price. A/C/E carbon and aluminum arrows are the best, followed by Apollo carbon arrows, X10 carbon, and aluminum arrows, and finally, X7 aluminum arrows are the worst.
