Cairns, Australia: Science of Sport Exercise and Physical Activity in the Tropics, 28-30 Nov 2013.http://hdl.handle.net/10092/10678Improved technology and increased competition has resulted in more cost-effective (~40% cheaper) global positioning system (GPS) technology options and widespread GPS usage amongst sports coaches. Coaches now routinely compare intra and inter-player match and training performances, and even at the international level budget GPS units are being employed including in tropical environments. However, few studies have quantified the validity and reliability of these commercially available budget GPS units (Visuallex Sport, New Zealand).enConference Contributions - OtherField of Research::11 - Medical and Health Sciences::1106 - Human Movement and Sports Science::110699 - Human Movement and Sports Science not elsewhere classifiedFields of Research::40 - Engineering::4013 - Geomatic engineering::401303 - Navigation and position fixing
