The objective of this project is to measure biomechanical variables such as force and acceleration in taekwondo athletes' joints through the automatic digitization of the movement of the human body in order to improve the athletes performance. The proposed system is based on a mobile application that, through the use of Artificial Intelligence (AI), Computer Vision (CV) and wearables for the acquisition of biometrics, can create a Digital Twin - a virtual representation and a reflection of the dynamic state of a physical entity. Tracking the person's movement without markers on the body, which later provides real-time feedback to the subject with the collected data.
