Monitoramento da escalada no equipamento peg board para prova de CrossFit®

Abstract

With worldwide growth of approximately 104,000% between 2005 and 2016, CrossFit® can be considered a major sport in the world. From this considerable growth, competitions seeking the best athlete were initiated and, with this, problems arose in relation to the fidelity of their results. Until 2017 the arbitration found in championships was human, thus allowing different interpretations arising from the subjectivity and individuality of the referees. This work presents the development of an electronic monitoring system for the “Peg Board” equipment used in CrossFit® competitions, aiming to provide athletes with an effective and linear arbitration. Motion detection is performed by magnetic sensors, whose information is processed by an ESP8266 NodeMCU ESP-12E module and then sent via wireless transmission to a server installed on a computer. Information such as number of rounds and repetitions will be stored in database, as well as the times of rise, descent, repetition, round and total time at the end. These elements will be presented via a graphical interface where they can be accessed from any device connected to the network.
