    Abstract: 本研究藉由文獻蒐集及彙整羽球專業教練的意見,探討歸納出羽球正手放網前球之技術模式。以數位攝影方式紀錄受試者放網前短球的動作,並將其動作加以分析,佐以專家之評估,驗證定性評估之可靠性,藉以提出動作修正之建議。本研究結果顯示,動作定性分析專業教練評分的相關值是很高的,同時歸納出優質的正手放網前球應具備良好的站位準備動作、正確的上網步法、穩定的身體軀幹動作,再加上靈活的手腕及良好的拍面角度,才能打出貼網的正手放網前球。而在檢驗受試者動作中發現其在站位準備動作時,球拍位置太低,跨步不足,有些微跳步情況完成最後一步的動作。另外身體穩定性不夠,體位下沉,有多餘往下的動作。擊球瞬間手臂太直,放鬆度不足,影響控球。此外,羽球過網高度亦稍微過高。經以技術模式分析評估後,提出以下之修正:準備動作時,拍頭應朝上一點。最後跨步時步幅需加大,早點到位,不要在停步時擊球。另上半身宜稍微往前,避免體位下沉,造成後退回防時腿部的負擔。觸及球時手肘應微屈,除了較放鬆之外也可增加觸球距離之適應性,可以避免球的過網高度不穩定,提高球過網之質量。
    The present research collected the discussion from references, and the opinions of professional coaches, proposed a skilled model of placing net-front balls by forehand for badminton players. Through digital photographic method, the exercised motions of selected testers were analyzed to examine the proposed skilled model. The assessment of experts was then added to testify its reliability, and followed by offering suggestions of modifying the movement. The investigation of the present work concludes that to place a high-quality net-front ball by forehand should possess good preparation motions, correct net front foot-work, and steady body motion. In addition, flexible wrist and a good angle of racket paddle would also helpful in hitting a good forehand drop shot in the net front. As for the part of examining the exercised motion of the tester, it was found that the position of the racket was held too low during preparation, and insufficient forward step resulted in finishing the last step by jumping. Secondly, the performance of the body of the testers seemed not stable enough, the upper body was too straight, caused a sinking body posture and surplus downward movement. Furthermore, the arm of the tester seemed too stiff at the instant of hitting a shot, i.e. not relax enough so that affected her ball controlling, that caused the ball flew too high while crossing over the net. Having assessed by the proposed skilled model, suggests of correction have been obtained as follows. First, the tester should uplift the racket a bit during preparation, and enlarge the final step in order to reach the position as soon as possible. Do not hit a shot while stopping. Secondly, upper body should lean forward to avoid the body posture sinking, which may cause additional burden of legs when doing defense return movement. Finally, the elbow should bend a little bit more while hitting a shot to gain a better control of the ball, and eventually would avoid the unstable crossing height of the ball over the net.
