基于肌肉力 - 速度概念的生理学原理，本文探讨了在确定和解读原位肌肉（尤其是人体肌肉）力 - 速度关系时所涉及的特殊问题。严格来说，在原位条件下，能够直接测量的并非力 - 速度关系，而只是关节的扭矩 - 角速度关系。这就需要借助生物力学模型计算，来获取参与关节运动的单个肌肉的力 - 速度关系。除了讨论这些基本原理，本文还详细阐述了使用所谓等速测力计进行测量时出现的方法学问题。鉴于等速测力法在全球已或多或少成为标准程序，本文的一个重要目的是让该方法的潜在使用者关注这些问题。本文还讨论了基于人体肌肉力 - 速度关系来表征肌纤维组成以及评估功率的可能性。最后一部分探讨了肌肉训练对扭矩 - 角速度关系的影响。本文内容可被视为一份指南，以避免在测量人体扭矩 - 速度关系时得出相互矛盾的结果。
Based on the physiological principles of the muscular force-velocity concept, this paper deals with the special problems associated with determining and interpreting force-velocity relations of muscles in situ particularly in humans. In the strict sense, instead of force-velocity relations merely torque-angular velocity relations of a joint can be measured directly under in situ conditions. This calls for biomechanical model calculations to obtain force-velocity relations of single muscles involved in joint motions. In addition to discussing these basic principles, the methodological problems arising in measurements with so-called isokinetic dynamometers are also explicitly described. An important message of this paper is to sensitize potential users of this method to these problems as the isokinetic dynamometry has more or less become standard procedure worldwide. The possibility of the characterization of muscle fiber composition and the evaluation of power on the basis of human muscle force-velocity relations is also discussed. A final section considers the effects of muscle training on the torque-angular velocity relations. The contents of this paper can be understood as a guide to avoid obtaining conflicting results when measuring human torque-velocity relations.
