. These parameters can be easily obtained from global positioning system (GPS) units attached to players. In particular, the recent and widely use of GPS devices monitors the player’s performance during training sessions and competitions, 17 recording various parameters. This information could help to

using 5-Hz global positionning system (Spi-Pro, Team AMS R1 2016.8; GPSports, Canberra, Australia). The reliability and validity of this system to measure distance and accelerations has been reported elsewhere. 7 Global positionning system data were further analyzed using an Athletic Data Innovation

pedestrian travel can be gathered with relative ease using either accelerometers or Global Positioning System (GPS) devices ( Chen, Janz, Zhu, & Brychta, 2012 ; Terrier & Schutz, 2005 ). Ideally, data from these sources could be integrated to enable greater comparative research and build on the specific
