Why the Martial arts principles of Tongbei and Liuhe were early principles of cutting-edge Sports Science
Tongbei (通背) or Posterior Chain Dominance is the engine. Liuhe (六合) or Kinetic Chain Coordination is the transmission system. The six external harmonies connect the body segments in proper sequence, minimizing energy leaks and force efficiently.Tongbei generates force; Liuhe transmits force, allowing power, speed, stability, and efficiency to become one integrated expression.
