“…The various field test protocols used to estimate the change-of-direction speed (CODS) must be valid and reliable for practical use. In sports practice, specific tests such as Lane Agility Drill, Reactive Shuttle Test-used in NBA when drafting players are most often used, while the most widely used tests with young players are the standardized Agility T-test (Delextrat & Coen, 2009;Sekulić, Uljević, Perić, Spasić, & Kondrić, 2017), Zigzag Drill Test (Bloomfield, Ackland, & Elliot, 1994;Karalejić & Jakovljević, 2009) and Y-shaped Agility Test (Lockie, Jeffriess, McGann, Callaghan, & Schultz, 2014). Although most of these tests contain some of the movement patterns used in basketball (running forward, running backwards and side step movement), different results obtained in the application of these tests in basketball players indicate certain shortcomings in diagnostics of the change of direction movement speed (Paoule, Madole, Garhammer, Lacourse, & Rozenek, 2000;Delextrat & Cohen, 2008;Chaouachi et al, 2009;Brown, 2012).…”
