射箭是一項看似容易但卻相當複雜的運動，其中的動作技巧往往都需要更多的時間與精力才能有所突破，所以除了反覆練習之外，更需要相關儀器協助偵測動作正確性與否。過去國內已有很多文獻針對影響射箭成績的關鍵因素作分析研究，例如：瞄射時間、手臂震顫、反應時間、持弓手的肌耐力...等等，但目前國內針對足底壓力參數介紹射箭運動的研究則較少，因此是否可從足底壓力的變異探究射箭運動表現合理性尚未有一定定論。本文首先將應用足底壓力及重心移動情形與站立式運動表現之關係進行介紹，接著介紹射箭運動之足底壓力分佈的變化情形，希望籍由本文提供射箭選手與教練作為評估練習表現時的參考。

Archery is a sport which seems simple but is quite complicated in reality, and players have to devote their time and energy to improve the skills required for archery. Besides repeated practice, applying instruments to judge the accuracy of archery motion is even more important. Many domestic studies have investigated the correlation between archery performance and certain key factors, such as aiming time, hand tremor, reaction time, muscular endurance of the bow arm, respectively. However, few of these studies considered planter pressure as a possible factor in archery performance, and the feasibility of assessing players' performance by planter pressure analysis is still an open question. In this study, first we introduced how to assess performance in perpendicular sport by planter pressure and weight shift analysis. Subsequently, we showed the variation of planter pressure under different shooting stances. Finally, we discussed the correlation between planter pressure and each archery phase. We hope our study can provide a performance estimation method for archery.
