骨骼肌纤维和结构特性都有助于肌肉的功能行为。本研究使用判别分析和数学建模，以确定结构和功能上的显着性能。纤维长度，肌肉长度，和羽角的建筑特性被认为是结构上最重要的参数，而纤维长度，肌肉长度，和纤维类型分布被认为是最功能性的决定。架构速度和光纤类型似乎不是互补的（即，速度的结构决定因素纤维长度与高固有速度的纤维无关）。然而，这两种属性类别与生产力之间似乎确实存在协同关系。具有大生理横截面积（PCSA）的肌肉往往含有更大比例的更大，更快的纤维。结构或形态上的重要参数并不总是发现有很大的功能效果。羽角，虽然最重要的结构变量之一，被发现有很小的功能效果。(C)1994 Wiley-Liss，Inc.
Skeletal muscle fiber and architectural properties both contribute to the functional behavior of a muscle. This study uses discriminant analysis and mathematical modeling to identify the structurally and functionally significant properties. The architectural properties of fiber length, muscle length, and pennation angle are found to be the most structurally significant parameters, whereas fiber length, muscle length, and fiber type distribution are found to be most functionally determining. Architectural speed and fiber type do not, appear to be complimentary (i.e., the architectural determinant of speed, fiber length, is not associated with fibers of high intrinsic velocity). However, there does seem to be a synergistic relation between the two property classes and force production. Muscles with large physiological cross sectional areas (PCSAs) tend to contain a greater proportion of larger, faster fibers. Structurally or morphologically significant parameters are not always found to have a large functional effect. Pennation angle, though one of the most structurally significant variables, was found to have very little functional effect. (C) 1994 Wiley-Liss, Inc.
