在骨骼肌中，纤维、腱膜和肌腱通常被认为是机械上“串联”的。这一概念导致过度简化计算肌腱力的纤维力，不正确的推导本构关系的腱膜，并在肌肉的拉伸缩短周期的弹性能量的恢复误解。在这里，我们从理论上证明，使用日益复杂的例子，肌腱和腱膜是不是在一个肌纤维腱膜肌腱复合体系列。然后，我们证明，假设肌腱和腱膜是在系列可以导致这些被动粘弹性结构的机械工作创建的外观，结果是机械上不可能的。最后，我们解释了不可压缩的肌肉基质的力学作用，从纤维的力传递到腱膜和肌腱，并强调，不可压缩性需要引入必要的额外的力来维持这种约束。不幸的是，这一要求消除了，但最简单的情况下，基于直观的自由体图的肌肉建模的理论方法。(c)2005爱思唯尔有限公司保留所有权利。
Fibres, aponeuroses, and tendons are often considered mechanically "in series" in skeletal muscles. This notion has led to oversimplified calculations of fibre forces from tendon forces, to incorrect derivations of constitutive laws for aponeuroses, and to misinterpretations of the recovery of elastic energy in stretch-shortening cycles of muscles. Here, we demonstrate theoretically, using examples of increasing complexity, that tendon and aponeurosis are not in series in a muscle fibre-aponeurosis-tendon complex. We then demonstrate that assuming the tendon and aponeurosis to be in series can lead to the appearance of mechanical work creation in these passive viscoelastic structures, a result that is mechanically impossible. Finally, we explain the mechanical role of the incompressible muscle matrix in force transmission from fibres to aponeuroses and tendon, and emphasize that incompressibility necessitates the introduction of extra forces necessary to maintain this constraint. Unfortunately, this requirement eliminates, for all but the simplest cases, a theoretical approach of muscle modeling based on intuitive free-body diagrams. (c) 2005 Elsevier Ltd. All rights reserved.
