Monitor de desempenho de golpes

Abstract

Combat sports are competitive sports where two fighters fight against each other abiding by certain rules of engagement. Boxing and mixed martial are the most popular and fastest growing combat sports and have become a major source of entertainment for fans and the general public. The training of martial arts fighters using punching bags is one of the simplest ways to apply and refine strokes, as punches and kicks. We notice, however, that the athlete has no quantitative response regarding your perfomance. In order to provide to fighters, information about their performance, this work aims to develop a system capable of monitoring fighter’s punches, so quantify the intensity of the blows in a workout, presenting to users a monitoring application that reports their performance. This system will have a sensor board in which an accelerometer will serve to capture the accelerations of punches from the fighter. The sensor board is adapted to the punching bag and contains a microcontroller that must acquire acceleration signals from the sensor, filter the signal, process it in order to obtain useful information about the coup, as a force, and send it in the form of package data through a bluetooth low energy wireless communication to a smartphone, which will contain an application. Through this application the fighters will be able to view the performance of their training. As results, we noticed that there are variations of sensor response according to the mass of the punching bag. Then, we develop statistical relationships that give us support for the correct calculation of force. So, this work brings a totally new system with a great background for further research on the theme.
