The aim of this study was to examine the relationship between change of direction-and-speed performance during a match and time on two change of direction-and-speed tests performed during the same season. 31 young soccer players participated in all conditions and were included in the analysis. Tests performed were the Modified Illinois Change of Direction Test (MICODT) and the Change-of-Direction and Acceleration Test (CODAT). Change of direction-and-speed performance during the match consisted of maximal achieved speed, acceleration, angular velocity and combinations of these, called speed-angular velocity surface, speed-acceleration surface, acceleration-angular velocity surface, and agility-boundary volume. These variables were calculated from position data gathered with the Local Position Measurement (LPM) system. A subdivision was made between low-speed movement (<4 m·s-1) and high-speed movement (≥4 m·s-1). Significant differences between the match, CODAT and MICODT were found for maximal values on speed, acceleration and angular velocity (F(12,19)=89.458, p < 0.001, η2=0.998). Relation between time on the test and match variables were similar for both tests. Significant correlations existed between time on the tests and acceleration, speed-angular velocity surface, speed-acceleration surface, acceleration-angular velocity surface and agility-boundary volume (r = -0.301 − -0.609). The highest correlations were found between time on the tests and the agility-boundary volume in low-speed movement and all movement categories (r = -0.532 − -0.609). Both tests are appropriate for giving an indication of change of direction-and-speed performance during a match and are equally suited for this. Using a complex construct, consisting of speed, acceleration and angular velocity, seems more appropriate to capture change of direction-and-speed performance.
