“…Unfortunately, none of these studies included any Holux GPS devices in their comparisons. The Qstarz is widely used in PA research (Andersen et al, 2017;Carlson et al, 2015;Evenson, Wen, Hillier, & Cohen, 2013;Hu, Li, Li, Houston, & Wu, 2016;Pizarro et al, 2017;Schipperijn et al, 2014;Stewart et al, 2017). The Holux RCV-3000 and its predecessor (Holux M-1000C) have been used in other scientific disciplines (Borkowski, Pietrzykowski, Magaj, & Maka, 2008;Hassein, Diachuk, & Easa, 2017), but only a few studies have used these devices in the field of PA monitoring (Arifin & Axhausen, 2012;Vorlíček, Rubín, Dygrýn, Mitáš, & Voženílek, 2016).…”
