title: Optimal kicking of a trampolinist.
abstract: This work aims to create a mathematical model by using kinematical equations that can describe the landing-jump of a trampoline performance. In this model, the trampolinist was assumed to be a combination of two parts of masses. The landing process (from the time trampolinist touches the net to the deepest location) was discretized into two stages. During these two stages, the trampolinist exerts different internal forces. Analyzing the kinematics of the abovementioned two stages, we obtained the numerical solutions for the optimum loading time and loading force of the trampolinist to get the deepest landing location. This work has potential for guiding a trampolinist in developing his/her personalized optimal strategy for exerting force during landing on the trampoline.
