The Relationship between the Performance of Soccer Players on the Curved Sprint Test, Repeated Sprint Test, and Change-of-Direction Speed Test

The curved sprint test is the most commonly used in team sports. From a practical point of view, it would be interesting to know what extent related direct and involving changes direction. This study investigated relationship between times taken by soccer players test, repeated direction, change-of-direction speed test. Two age groups U15 U17 (n = 22) took straight total time did not differ significantly from (46.80 ± 1.85 s 34.51 1.66 s, respectively; T 120). was different direction 82.36 4.47 115). There no significant correlation (CST) (RSCD) (r 0.180). also (RSST) 0.301). non-significant these abilities implies that they are independent each other may have tested trained complementarily.
