Purpose: Agility in young soccer players has long been associated with physical attributes like strength, speed, and power. The aims of this study were to investigate the relationship between cognitive factors and agility performance in this unique population. Methods: 39 young soccer players age 13.56 (SD 0.58) years were assessed for leg-muscle function (jump tests) and maturation status (peak height velocity). The Y-Agility Test, which included decision making in players, was used to measure performance. Cognitive factors such as perceptual skills and decision making were evaluated with the Y-Agility Test. Results: The linear regression showed an absence of significance between the Y-Agility Test and drop-jump contact (P =.283), Y-Agility Test and drop-jump flight (P =.185), Y-Agility Test and squat jump (P =.868), and Y-Agility Test and countermovement jump (P =.310). The linear mixed-model analyses suggested a difference between early-average maturers (P =.009) and early-late maturers (P =.005) but did not show a difference between average-late subjects (P = 1.000). Drop-jump flight did not show a difference in maturation (early-average P = 1.000; early-late P = 1.000; average P = 1.000). Squat-jump performance did not demonstrate any significance (early-average P =.618; early-late P = 1.000; P = 1.000). Countermovement-jump performance did not show any significance (early-average P = 1.000; early-late P = 1.000; average-late P =.492). Finally, agility performance does not show any significance between maturation levels (early-average maturer P =.450; early-late P = 1.000; average-late P =.830). Conclusion: Agility in young soccer players appears to follow a nonlinear trajectory, with cognitive factors possibly playing a more significant role than previously thought.
