本研究的目的主要在探討籃球的跳投動作特性分析，期望從球員的投籃動作中，找出問題，幫助球員在比賽中提高投籃的命中率。利用文獻分析法分段說明投籃動作的下肢運動學、上肢運動學、以及出手後球體的旋轉來加以探討。結果發現跳投技術的過程中是在極短時間內完成的，投籃動作各個環節是緊密的連在一起，必須使身體的各環節在同一時間的屈、伸中完成出手，而造就了正確的投籃動作。正確的投籃動作，是提高命中率的重要因素，建議籃球教練在指導球員時，必須找出球員投籃命中率低的問題，如接球動作的錯誤、身體和腳分段投籃、練習不足等，適時的幫助球員度過低潮，進而提升球員的投籃命中率，幫助球隊能有好的表現。

This study mainly discussed the analysis of basketball jump shot motion characteristics. Hoping the results help to find out the shooting problems of players and increase field goal percentage. Literature analysis method was used to explain the shooting movement analysis of upper limb kinematics, lower limb kinematics and how the ball rotated after being delivered from the player. The results appeared that jump shot technique process completed in an extreme short period. Every movement of shooting linked closely together. The correct shooting movement depends on every section of body to crook and stretch simultaneously. The correct shooting movement is the critical factor of increasing field goal percentage. It is suggested that coaches should find out the problems of low field goal percentage, such as wrong ball catching techniques, shooting with uncoordinated body and feet, and unpracticed to help players go throw the frustration and raise field goal percentage and team strength.
