采用新式腘绳肌测试仪可减少运动损伤发生概率
昆士兰科技大学9月29日报道，最近昆士兰科技大学（QUT）的研究人员研制出了一种具有突破性的仪器。该仪器可以帮助顶尖职业运动员评估并减少腘绳肌损伤风险。该仪器为目前全世界唯一一种可以在诺迪克腘绳肌屈伸动作（Nordic hamstring curl）中进行肌肉力量测量的便携式装置。 [国际体育科教资讯服务]

研究团队首次证明腘绳肌损伤风险是可以通过测量运动员进行诺迪克屈伸动作时腘绳肌的力量来进行量化的。腘绳肌力量提升10牛顿可以将腘绳肌损伤降低约9个百分点。澳大利亚的一些重量级俱乐部已经开始使用原型设备，而该研究团队也已经开始在橄榄球联盟、NRL、板球以及A-联赛（足球）俱乐部中开展相关初期测试。

Beijing Sport University From Wikipedia, the free encyclopedia

Beijing Sport University (BSU) (Chinese: 北京体育大学) (formerly Beijing University of Physical Education), founded on November 1, 1953,3 has contributed greatly to the sustainable development of Chinese sport and physical education and has enjoyed the fame as one of the key sport universities in China.

I would imagine that they have good enough credit to trust the material they put out.
