摘要

本研究針對羽球線在持續拍擊下的拍擊力量進行分析，球拍和球線由百弘體育用品有限公司提供，球線則穿到22、26和30磅以進行測試。實驗時，首先將球拍固定於GOTECH測量儀，之後讓測量儀持續揮動球拍進行模擬比賽並測量球拍撞擊羽球頭時的拍擊力量，最後針對不同模擬比賽時間點與比賽分數下的拍擊力量進行比較，結果顯示：
一、在持續拍擊模擬比賽下，不同比賽時間點、比賽分數對於羽球線拍擊力量產生影響。
二、本研究球線拍擊力量並沒有產生規律性變化，和球線自然退磅的規律性變化不同。
三、在同一比賽時間點—不同比賽分數下，22磅低穿線磅數球線拍擊力量改變幅度不大，較為穩定；反之，26磅中穿線磅數與30磅高穿線磅數球線拍擊力量的改變幅度較大，較不穩定。
四、在不同比賽時間點—相同比賽分數下，30磅高穿線磅數球線拍擊力量曲線最小值會出現在第96或第120小時，較26磅中穿線磅數與22磅低穿線磅數的第72或第96小時來的晚；另外30磅高穿線磅數球線拍擊力量的改變幅度也較大。

In this research, hitting forces of badminton strings in continuous hitting situation were aimed to study. All rackets and strings were offered by PAI-HONG SPORTS GOODS CO.LTD. Strings were strung into the rackets at 22, 26 and 30 pounds respectively to study. In experiment, rackets were fixed at GOTECH measuring instrument firstly and then used the instrument to wave rackets continuously to complete simulating games and measure hitting forces when rackets hitting badminton sphere simultaneously. Lastly, hitting forces at different times and scores of simulating games were aimed to compare. Results showed: 1. In continued simulating games, different times and scores would effect hitting forces of badminton strings. 2. Unlike the regular changing of declination of string’s tension, hitting forces of badminton strings weren’t showing regular changing. 3. When in the situation of same time-different score, the changing of hitting force wasn’t obvious and hitting force was stable when the string strung at low thread pound (22 pounds). On the contrary, the changing of hitting force was obvious and hitting force wasn’t stable when the string strung at mid thread pound (26 pounds) and high thread pound (30 pounds). 4. When in the situation of different time-same score, the hitting force curve minimum value of high thread pound (30 pounds) string was occurring at the 96th or 120th hour, later than the happening times (at the 72th or 96th hour) of mid thread pound (26 pounds) and low thread pound (22 pounds) strings. Moreover, the changing of hitting force of string strung at high thread pound (30 pounds) was obvious than the changing of hitting forces of strings strung at the other two thread pounds.
