Aim: The efficient use of the prefrontal cortex (PFC) plays a crucial role in athletes' mastery of technical and tactical skills, enabling them to perform at a high level by making sound decisions during competitive encounters. However, the effects of dual-task paradigms on the PFC in athletes remain unclear in the literature. The aim of this study was to investigate the effects of dual-task (cognitive + motor) paradigms presented at varying levels of difficulty on PFC hemodynamic responses. Methods: This study included 14 athletes (mean age = 12 ± 1.56 years), randomized to the "Dual Task" paradigm (P1: motor task; P2: cue task; P3: complex cue task). Dual task performance was measured using the Fitlight system, where participants extinguished 25 lights at varying difficulty levels. In P1, participants extinguished randomly lit lights; in P2, they did so faster as the next light appeared in the same color region; in P3, a more complex cue indicated the light region, requiring altered motor control. Hemodynamic responses in the prefrontal cortex (HbO, HbR, HbT) were assessed using fNIRS during task performance. Results: Significant differences were observed in the competition time of the test between the P1 and P2 tasks (p < 0.001), as well as between the P1 and P3 tasks (p < 0.001). fNIRS data demonstrated a higher level of cortical activation in the prefrontal cortex during the P3 task compared to other tasks; however, this difference was not statistically significant (p = 0.257). A strong and statistically significant positive correlation was identified between the hemodynamic responses and the P1, P2, and P3 tasks (p < 0.001). Conclusion: Task protocols with higher cognitive load resulted in an increase in HbO, HbR, and HbT values, which were proportional to task difficulty in prefrontal activation. Keywords: dual-task, cognitive load, prefrontal cortex, fNIRS
