Background technique

From an anatomical point of view, the core of the human body refers to the spine, hip joints, and pelvis, which are at the junction of the upper and lower limbs and serve as a link between the preceding and the following. Core strength includes core stability strength and core dynamic strength. Core stability strength refers to the ability of the core to resist or rotate the body when the fixator muscles or some muscles that are both fixator muscles and prime mover muscles contract. Core dynamic strength refers to the force of skeletal muscle contraction to produce displacement or rotation of the body. Core strength is not only the main driving force for the formation of the core stability of the human body, but it can also actively exert force during exercise. Core strength training is usually carried out under unstable conditions, which can make the muscle groups of the human body, especially the auxiliary muscles around the joints, participate in sports, and improve the ability of athletes to stabilize joints and control centers during sports. The posture of core muscle training is determined by the sports competition. Action decides.
