A practical monitoring system for measuring kinetical variables of semi- professional athletes

The development of monitoring systems that can allow the efficient tracking and datalogging of athletes’ performance is an ever-evolving task due to the difficulty to fulfill the required specifications: (1) high- sampling rate, (2) accuracy, (3) portability. In this sense, the development of inertial measurement unit- based systems can allow achieving the aforementioned features, since the basic sensors that are employing have a similar sensitivity that vision-based systems. This paper presents the development of an accelerometer- based system to measure kinetic variables of semi- professional athletes using a low-cost processing controller. The obtained results show the proposal performs as expected, as the physical quantities (acceleration and velocity) values are within the range of the reported values in the state-of-the-art.
