摘要

緒論：高爾夫球開球距離與準確度極重要，因其可優化球道策略之執行。近年職業賽事中已導入科技儀器，即時蒐集彈道飛行參數作為運動表現之依據，相關業餘賽事中未有此數據。故本研究於業餘賽事蒐集彈道飛行數據，並探討業餘參與者運動表現與運動表現之關聯。方法：本研究對象以男性業餘高爾夫參與者（共143名），蒐集其一號木桿開球參數。資料蒐集儀器為多普勒雷達（Doppler radar; 20KHz），以擷取彈道飛行與揮桿技術參數。分組依照該當日成績依據USGA差點分成三個組，分別為高差點組（high-handicap, HH）、中差點組（mid-handicap, MH）、與低差點組（low-handicap, LH）。統計方法為獨立樣本單因子變異數分析 （one-way analysis of variance, one-way ANOVA），並用Scheffé法事後比較。結果：顯示各組別在開球距離都達顯著。低差點組於球速與桿頭速度達顯著。高差點組於擊球效率與動態傾角達顯著。低差點與高差點組出球角度與總旋轉值達差異，前者向目標右邊之桿頭路徑與負球旋軸心。結論：本研究結論業餘參與者欲降低差點以增加距離為首要，欲進階到低差點者須提升桿頭速度與球速度。高差點者建議須提升擊球於甜蜜區提升擊球效率，亦可降低總旋轉值。建議高差點者多採用符合一號木桿的D平面擊球方式，如內向外的平面與桿頭路徑，更容易擊出左曲球之旋轉軸心。

Introduction: Golf drive distance and accuracy are vital parameters for golf performance and can enhance course strategy. Professional tours have implemented technology to capture golf driving characteristics during tournament. The purpose is to analysis golf drive characteristics between the different handicap of golfers during tournament. Method: Subjects were male amateur golfers (N =143). Subjects were divided into three groups based to the final score, into three categories, high-handicap group (HH), middle-handicap group (MH), and low-handicap group (LH). The study used Doppler radar (20KHz) to capture ballistic flight, golf swing technique parameters. One-way ANOVA (α = .05) was used to analysis the data and Post-Hoc with the Scheffé method. Results: The differences between the handicap group is distance. Low-handicap group have faster initial ball velocity and clubhead velocity. Mid-handicap group differs from high-handicap group in smash factor, backspin and driving distance. Low-handicap group have lower dynamic loft, attack angle, backspin, and higher swing efficiency than high-handicap group. High-handicap golfers should enhance their swing techniques by adjusting their swing direction to more right of target inside-out, with square or a left-of-path face angle at impact. Conclusion: This study found that the main contributor for amateur golfers to lower handicap is to increase drive distance. Those want to become single digit handicap must focus on increasing the clubhead and ball velocity. High-handicapper should focus to impact closer to sweet spot to increase smash factor and for lowering backspin. Additionally, high-handicapper are suggested enhance techniques with an inside-out swing path accompanied for draw trajectory.
