Abstract: Objective: : By using the method of documents and expert interview, this paper analyzes the status quo of core strength training research. The results show that people's perception of core strength training is divergent, and the fact that many people follow blindly the hot topics has an increasing negative effect; findings through fuzzy reasoning and speculative estimation are short of quantitative support, and are subject to verification. The paper analyzes the viewpoints on core strength training in a rational way, and proposes that the core of rehabilitation training and athletic training feature not only integrity, systematicness, goal orientation, but also periodicity and dynamics; The core area of rehabilitation training should be the injured area the linkage area of injury mechanism, while the core area of athletic training should be the systematic function area involving the special "kinematic chain"; In the special quality and ability, power is the foundation, and speed is the core; The focus of core strength training is not to develop the core stability and the core strength, but to develop the integration and regulation ability of nerve-muscle system; The core area of locomotive anatomy, is neither the core area of body stability, nor the power source of momentum accumulation,but one step in the process of body stability and momentum accumulation.

Key words: Rehabilitation Training and Athletic Training, Core Area, Core Strength, Core Stability, Special Core Competence
