This brings us to the kinetic chain. What is the kinetic chain?Simply put, it is the leg force (the source is the reaction force of pushing off the ground), which is transmitted to the crotch and waist, and the waist turns and the body moves (plus the force of coil, uncoil).Waist stop (deceleration) to the shoulder, shoulder turn arm movement (plus arm strength), shoulder stop (deceleration) to the elbow, forearm, wrist, hand, head.This involves the use of muscles and tendons, as well as the range of motion of joints, restrictions and so on.Modern biomechanics, especially the analysis of various sports, will consider how to establish an optimal way of power training.To achieve the effect of certain actions most efficiently.
