BACK GROUND AND PURPOSE: Hamstring injury is a common occurrence in sport and there has been limited success in reducing this rate of recurrence to date.
High speed running requires eccentric strength when the hamstring muscles are in a lengthened state. The lengthened state occurs when the hip is in flexion and the lower leg moves into extension, thus lengthening the two joint hamstring muscle over both articulations upon which they act. There is evidence to suggest that athletes who have sustained a hamstring strain lack strength when the muscle is utilized during performance in a lengthened state.
To examine the risk factors contributing to such a high recurrence rate and propose a unique rehabilitation strategy addressing these factors in order to decrease the rate of reinjury.
DISCUSSION/RELATION TO CLINICAL PRACTICE: Failing to increase an athlete's eccentric strength in a lengthened position after a hamstring injury may predispose an athlete to subsequent reinjury. Incorporating lengthened state eccentric training may help reduce the rate of reinjury.

背景与目的：腘绳肌损伤在体育运动中很常见，迄今为止，在降低其复发率方面成效有限。
高速奔跑时，当腘绳肌处于拉长状态时需要离心力量。当髋关节处于屈曲且小腿伸展时会出现拉长状态，从而使双关节腘绳肌在其作用的两个关节上都被拉长。有证据表明，曾发生过腘绳肌拉伤的运动员在肌肉处于拉长状态下进行运动时力量不足。
研究导致如此高复发率的风险因素，并提出一种独特的康复策略来解决这些因素，以降低再次受伤的发生率。
讨论/与临床实践的关系：腘绳肌损伤后未能增加运动员在拉长位置的离心力量，可能会使运动员更容易再次受伤。纳入拉长状态下的离心训练可能有助于降低再次受伤的发生率。
