The leg joint mechanism in human hopping was modeled, and the numerical simulation was carried out. The movement of each joint during jumping is studied by deriving the equation of the motion based on the Lagrange method, giving the initial value based on an actual human body, and adjusting the numerical values. The feature of the movement of each joint in the jump's moving was able to be captured by solving equations by using the fourth Runge-Kutta methods for the temporal integration. Since the rigidity and the damping coefficient in each joint are adjusted until it succeeds to land, before falling. Therefore, the problem in simulating the jump movement of the human human hopping was partially clarified.
