Eleven elite youth futsal players performed a circuit with different type of displacements as sprinting, running at low-medium intensity, standing up and changes of direction. Data recorded by the Overtraq system were compared with video-analyzer during the six trials of each player. Standard error mean, Intraclass Correlation Coeficient and Coefficient of variation, were calculated to analyze the reliability of the device, as well as the Root Mean Square Error and Confidence Interval with correlation of Pearson for its validity. The results reported good validity for three intensity ranges (R2>0.7) with high reliability (Intraclass Correlation Coeficient: 0.8–0.9), especially for high intensity actions (Intraclass Correlation Coeficient: 0.95, Coefficient of Variation: 3.06%). Furthermore, the validity for the number of different actions was almost perfect (96.3–100%), with only small differences regarding changes of activity (mean error: 2.0%). The Overtraq system can be considered as a valid and reliable technology for measuring and monitoring actions at different intensities and changes of direction in futsal, likewise common actions for other indoor sports. date: 2021-03 date_type: published publication: International Journal of Sports Medicine volume: 42 number: 03 pagerange: 253-258 pages: 0 id_number: doi:10.1055/a-1244-9985 refereed: TRUE issn: 0172-4622 official_url: http://doi.org/10.1055/a-1244-9985 num_pieces: 0 gscholar_impact: 0 gscholar_datestamp: 0000-00-00 00:00:00 access: close language: en citation: Artículo Materias > Educación física y el deporte Universidad Europea del Atlántico > Investigación > Producción Científica Cerrado Inglés The purpose of this study was to analyze the validity and the reliability of the intensity ranges, number of actions and changes of direction measured by a commercial inertial measurement unit.
