Have you ever wondered which part of the body moves the fastest to the acceleration phase of an athlete? Or where in the body do we have a more linear trajectory during the race? This project was born from the will to answer these and many other questions in the framework of a biomechanical study of the acceleration phase of an athlete in speed tests.

The work has been structured as follows: firstly, interesting data on the movement chosen has been obtained through the School's mocap technical team and a video in the "kinovea" software that will allow us to see the data and trajectories of a very graphic mode. Afterwards, the generated data was analyzed and those that were considered most relevant for the next step were selected: the robotization of movement. In this last step, an attempt has been made to reproduce one of the numerous movements in the study in the form of a robot.

The movement chosen to analyze is the departure of a sprinter. The output of a sprinter has two variants, the competition and the training. In the first, the action tries to get out as fast as possible right after hearing the starting shot, with a standard technique that deals with the support of the feet in the starting blocks and both hands on the ground, guaranteeing better acceleration initial. And on the other hand, the training output or output to three supports is what we have represented and analyzed. It consists of the support with one hand on the ground and the exit with the toes touching the ground without any additional structure that helps the explosiveness of the athlete.
