Validity of a new tracking device for futsal match

Abstract

Purpose: The purpose of this study was to to evaluate the validity of a new tracking device that allows measuring different performance factors in futsal real game situations.Methods:10 high elite futsal players performed a typical futsal training task, this is, a 4v4 in 28×20m with a duration of 180 seconds, where players wore two tracking devices, the new one (OLIVER) and the already validated device (WIMU PRO). Data recorded by the OLIVER and WIMU PRO systems were compared after the training session. Descriptive analysis was performed for each variable, and a one-way ANOVA was developed to calculate the validity of OLIVER compared with WIMU PRO report.Results:The results reported good validity for most of the variables analysed, such as the total distance (P = .385), the distance traveled at high intensity (P = .786) and maximum intensity (P = .460), as well as the number of accelerations (P = .690) and decelerations (P = .073) and maximum speed (P = .114). However, the distance traveled at low speed (P = .013) and the number of high accelerations (P = .028) reported statistical differences from OLIVER to WIMU PRO.Conclusions: The OLIVER system can be stated as a valid technology for monitoring most of the external load variables in specific training tasks in futsal, which ensures an improvement in the monitoring training process.
