由先前對籃球出手型態的研究可以知道投籃在比賽中是一個非常重要的技術。雖然跳投的命中率常因為距離籃框遠的關係而較其他出手方式低，但在高層級的籃球比賽中跳投仍然是最常被使用的得分技術。跳投前的腳步是球場上的基本動作：踏步，一二步停，跳步停及轉身。這些腳步不只可以在跳投前使用，也是籃球場上跳躍，停止，轉換方向必須的動作。在不同層級的比賽中，由於技術能力、體型及速度不同，基本技術的表現可能會有不同；此外，競爭激烈的程度在同一個層級的比賽中亦有不同。本研究以業餘籃球競賽中具高技術水準之歐洲男子籃球錦標賽為範圍，將比賽分差使用集群分析，分成小比分、中比分、大比分差的比賽，再以影片標記分析的方法，探討跳投前不同腳步使用的次數與結果。結果顯示在2015年歐錦賽男籃中比分中（10到23分），敗隊的跳投次數明顯高過勝隊，勝隊的出手被犯規多於敗隊。中比分及大比分(25到30分)勝隊出手命中率顯著高於敗隊。無論比分差距、收球方式，一二步是最常用的跳投腳步，跳步跳投次之，踏步、轉身及無腳步跳投數量最少，其中轉身腳步跳投在禁區數量較多，有別於無腳步跳投在三分球較多的現象。在大比分中勝敗隊的命中率有顯著差距，其中一二步、跳步皆是勝隊高於負隊，唯有踏步跳投命中率為負隊高於勝隊。跳投的次數越遠越多，並以接球為主；中距離跳投命中率較三分球跳投高。建議以最少次數的跳投腳步，無腳步投籃開始學習跳投，而高水準籃球選手的訓練應強調外線接球跳投。

Shooting is a very important technique in basketball games based on previous studies on the types of field goals analyzed. Jump shot is one of the most used techniques to score in high level basketball games although the shooting accuracy may be suffered from the broader range of shots. The footwork on jump shots is part of the basic body movements on court: step, one two stop, jump stop, and turn. These types of footwork are not only used before jump shots, but also essential movements to jump, stop and to change directions on court. These basic skills might emerge in different ways because of different skill levels, physical characters, and moving speeds in different levels of basketball leagues. In addition, the competition intensities in the same league may also affect the application of these basic skills. Therefore, the purpose of the study was to examine the influence of different types of footwork on the frequency and outcome of jump shots for the European men’s basketball championship under different game results. The results show that losing teams jump shot more and received less shooting fouls than winning teams in the group of medium point difference (10-23). Field goal percentage was significantly higher for winning teams in both medium and large point difference (25-30). For all 3 groups of point difference and 2 types of action before the jump shots, the frequency of the footwork recorded from the highest to the lowest was one two stop, jump stop, step, turn, followed by jump shot without footwork. Turn jump shot was found more in the post, in contrast to jump shot without footwork found most at perimeter. On shooting percentage, one two stop jump shot, jump stop jump shot were both higher in winning teams of large point difference, but losing teams performed better than winning teams in step jump shot. Based on the findings, we suggest that the progression of footwork before jump shot when learning to play basketball should start from shooting without footwork. In addition, for the training of elite level of basketball, emphasis should be made on three-point catch and shoot jump shot.
