過去的研究顯示部分羽球選手都曾發生阿基里斯腱(Achilles tendon)的傷害，但其中的機轉並不清楚。本研究以6位羽球校隊之選手為對象，以Mega Speed MS1000高速攝影機，取樣頻率500Hz 及AMTI BP400600測力板，取樣頻率1,000Hz同步記錄前跨步、前大跨步、輕跳前跨與輕跳後退動作的運動學及動力學參數，並以逆動力學(inverse dynamics)的方式計算阿基里斯腱力，藉此探討傷害發生的原因。結果發現前述四個動作中，最大阿基里斯腱受力分別為3,920、4,560、4,268、4,160N，且發生的時間點多在踝關節由背屈轉為蹠屈時。這樣的動作在羽球中是常見的，也因此羽球選手之阿基里斯腱常需承受較大力量，而提高發生傷害的可能性。

Past studies have shown that most badminton players suffer Achilles tendon injuries. However, the causes of Achilles tendon injuries are still not clear. This study investigated the mechanism of Achilles tendon injuries by the biomechanical analysis. Six university badminton team players volunteered as subjects in this study. Each subject was asked to perform four different kinds of footwork: (1) forward lunge; (2) larger forward lunge; (3) two or three ready hops followed by racket foot forward lunge; (4) two or three ready hops followed by racket foot backward step. A high-frequency camera (Mega Speed MS1000, 500Hz) and a force plate (AMTI BP400600, 1,000Hz) were used to record the kinematical and kinetic data. The Achilles tendon force (ATF) was calculated by the inverse dynamics process. The results showed that the maximum ATF in different types of footwork were 3,920, 4,560, 4,268 and 4,160 Newtons, respectively. The time that maximum ATF occurred was close to the moment when the ankle joint changed from dorsi-flexion to plantar-flexion. This pattern of ankle motion was prevalent in badminton players. That accounted for the fact that the badminton players mostly needed to bear the heavy load on the Achilles tendon, which resulted in the increasing the possibility of Achilles tendon injuries.
