Abstract
The validity and reliability of global positioning technology (GPS) for measuring the physical demands of various sports have been questioned (1,2,3). Court-based sports are characterized by rapid changes in direction within a confined space (4,5,6,7). Thus, one would expect lower quality of GPS data compared to eld sports (8,9,10).
