人体骨骼肌是由不同类型的肌纤维组成的。(1-3)这种肌纤维类型的范围允许人类肌肉显示各种各样的能力。此外，肌肉纤维可以通过改变尺寸或纤维类型组成来适应不断变化的需求。这种可塑性是许多旨在增加患者力量发展或耐力的物理治疗干预措施的生理基础。纤维类型组成的变化也可能是部分原因，因为长期不活动，肢体固定或肌肉去神经支配而导致的患者中出现的一些损伤和残疾。(2)在过去的几十年里，用于对肌纤维进行分类的技术数量有所增加，从而产生了几种分类系统。本更新的目的是提供必要的基础知识，阅读和解释人类骨骼肌的研究。肌纤维类型可以使用组织化学，生物化学，形态学或生理学特征描述;然而，不同技术的肌纤维分类并不总是一致的。(1)因此，可以通过一种分类技术分组在一起的肌纤维可以使用不同的分类技术被放置在不同的类别中。对肌肉结构和生理学的基本了解是理解肌纤维分类技术所必需的。
Human skeletal Muscle is composed of a heterogenous collection of muscle fiber types.(1-3) This range of muscle fiber types allows for the wide variety of capabilities that human muscles display. In addition, muscle fibers can adapt to changing demands by changing size or fiber type composition. This plasticity serves as the physiologic basis for numerous physical therapy interventions designed to increase a patient's force development or endurance. Changes in fiber type composition also may be partially responsible for some of the impairments and disabilities seen in patients who are deconditioned because of prolonged inactivity, limb immobilization, or muscle denervation.(2) Over the past several decades, the number of techniques available for classifying muscle fibers has increased, resulting in several classification systems. The objective of this update is to provide the basic knowledge necessary, to read and interpret research on human skeletal muscle.Muscle fiber types can be described using histochemical, biochemical, morphological, or physiologic characteristics; however, classifications of muscle fibers by different techniques do not always agree.(1) Therefore, Muscle fibers that may be grouped together by one classification technique may be placed in different categories using a different classification technique. A basic understanding of muscle structure and physiology is necessary to understand the muscle fiber classification techniques.
