To demonstrate the potential for a simple clinical test of hamstring muscle strength to identify susceptibility to muscle strain injury.
A single-case design was used; specifically, an elite-level male Australian Rules football player performed bilateral isometric maximum voluntary contractions of the hamstring muscles on a weekly basis for a period of 5 weeks preceding a right hamstring muscle strain injury.
Minimal asymmetry (no greater than ±1.2% difference) was evident in the hamstring isometric maximum voluntary contractions during the first 4 weeks, but 5 days prior to injury, the right hamstring isometric maximum voluntary contraction was reduced by 10.9% compared to the left.
Measuring asymmetry in isometric maximum voluntary contractions of the hamstring muscles may be a useful clinical test to identify susceptibility to muscle strain injury.
证明通过一项简单的临床测试来评估腘绳肌力量，以此确定肌肉拉伤易感性的可能性。
采用单病例设计；具体而言，一名精英水平的澳大利亚式橄榄球男子运动员，在右侧腘绳肌拉伤前的5周内，每周进行双侧腘绳肌等长最大自主收缩测试。
在前4周，腘绳肌等长最大自主收缩中，两侧差异极小（不超过±1.2%），但在受伤前5天，右侧腘绳肌等长最大自主收缩较左侧降低了10.9%。
测量腘绳肌等长最大自主收缩的不对称性，可能是一种有用的临床测试，有助于确定肌肉拉伤的易感性。
