In sports medicine, disorders of muscle function and muscular imbalance play an important role in both risk of injury and lack of improvement. They are highly important for the trunk muscle function, since low back pain is one of the most common disorders of sportsmen and is usually diagnosed as "functional disorder" without further specification. Despite its relevance, little is known about the specific capabilities of trunk muscle function in elite sportsmen. This study describes the measurement of trunk muscle torque, velocity, endurance and coordination in elite sportsmen. The study was performed by clinical examination and an isoinertial testing device (ISOSTATION-B200, Isotechnologies, Hillsborough, NC, USA). The results of a study of 20 German elite male rowers are presented and the relevance of these results is discussed in respect of their implications for training and therapy in injured athletes. Mean torques in extension and flexion were 319 Nm and 295 Nm, respectively. Elite rowers were stronger in isometric torque in all planes compared to normals and other sports groups, such as tennis players and swimmers. The better the rowing performance was, the lower was the extension/flexion ratio, the coordination and the decrease in velocity during endurance testing. This testing procedure is a useful tool in the measurement of trunk performance in elite sportsmen.
在运动医学中，肌肉功能紊乱和肌肉失衡在受伤风险和恢复不佳方面都起着重要作用。它们对躯干肌肉功能非常重要，因为腰痛是运动员最常见的病症之一，通常被诊断为“功能紊乱”而无进一步明确说明。尽管其具有相关性，但关于精英运动员躯干肌肉功能的具体能力却知之甚少。本研究描述了对精英运动员躯干肌肉扭矩、速度、耐力和协调性的测量。该研究通过临床检查和等惯性测试设备（ISOSTATION - B200，Isotechnologies，美国北卡罗来纳州希尔斯伯勒）进行。展示了对20名德国精英男性赛艇运动员的研究结果，并就这些结果对受伤运动员训练和治疗的影响进行了相关性讨论。伸展和屈曲的平均扭矩分别为319牛米和295牛米。与正常人以及其他运动群体（如网球运动员和游泳运动员）相比，精英赛艇运动员在所有平面的等长扭矩方面更强。赛艇成绩越好，伸展/屈曲比率、协调性以及耐力测试期间的速度下降就越低。这种测试程序是测量精英运动员躯干性能的有用工具。
