骨骼肌产生的力随肌节长度和速度而变化。运动过程中发生的肌节长度变化的理解提供了这种关系的生理重要性的见解，并可能提供某些肌肉/关节组合的设计见解。本综述的目的是总结和分析现有的文献发表的肌节长度的工作范围报告的各种物种。我们的第二个目的是应用分析技术，以确定是否可以概括的“正常”肌节长度的骨骼肌的工作范围。分析表明，许多肌肉在狭窄的肌节长度范围内运作，覆盖最佳肌节长度的94+/-13%。肌节长度的测量被发现是系统的影响，严格的状态和方法，用于使这些测量。
The force generated by skeletal muscle varies with sarcomere length and velocity. An understanding of the sarcomere length changes that occur during movement provides insights into the physiological importance of this relationship and may provide insights into the design of certain muscle/joint combinations. The purpose of this review is to summarize and analyze the available literature regarding published sarcomere length operating ranges reported for various species. Our secondary purpose is to apply analytical techniques to determine whether generalizations can be made regarding the "normal" sarcomere length operating range of skeletal muscle. The analysis suggests that many muscles operate over a narrow range of sarcomere lengths, covering 94+/-13 % of optimal sarcomere length. Sarcomere length measurements are found to be systematically influenced by the rigor state and methods used to make these measurements.
