核心稳定性是在一个完整的动力链中,为保证力量和运动能够最适宜地产生、传递、控制至四肢末端,而具有的控制躯干位置和运动的能力。其实质是保持脊柱中立区域在一定生理范围内以避免临床不稳定。核心稳定性有赖于控制、被动以及主动三个子系统的协同工作。根据所处位置及功能可以将核心区肌肉划分为：局部稳定肌、整体稳定肌和整体运动肌。核心区肌肉在保持、促进核心稳定过程中是作为一个整体的功能单位进行活动的,但肌肉的动员存在一定的层次性。这也为核心稳定性训练提供了科学依据。

Core stability is the ability to control the position and motion of the trunk over the pelvis and leg to allow optimum production,transfer and control of force and motion to the terminal segment in integrated kinetic chain activities.The essence is to remain the neutral zone within certain physiological thresholds to avoid clinical instability.Core stability system consists of three subsystems： the neural subsystem,the passive subsystem and the active subsystem.Based upon their location relative to the joint they attach and their function,the core muscles can be divided into three categories： the local stabilizing,global stabilizing and global mobilizing muscles.The core operates as one integrated functional unit when to maintain and promote core stability.The core muscles,however,are somewhat of a layered system of operation.At the same time,it provides a scientific base for the training of core stability.
