Abstract: To enrich the theoretical system of functional training, the paper clarifies the training mode of functional training. Through literature review, expert interviews and taxonomy, the paper summarizes, refines and classifies the theoretical system of functional training methods at home and abroad. Conclusion: 1) the functional training system is laterally divided into functional movement system, functional training system, corrective action system, activating and regenerating system; 2) functional movement system includes functional movement screening (FMS), selective functional movement assessment (SFMA), Y- balance test (YBT); 3) functional training system consists of the seven plates of activation and regeneration, operation mode, rapid expansion of training complex, multi-directional speed, energy metabolism, functional strength, core training; 4 )functional operation mode is divided into upper limb exercises in three planes, lower limbs, trunk, upper limbs and trunk combination, a combination of lower limbs and torso and the six kinds of push, pull, rotate, flexion and extension involving the whole body. This study helps to clarify analyzes the he main content of functional training system in order to provide practical guidance and reference fro China’s functional training theories.
