dc.description.abstractObjectives. - The prefrontal cortex (PFC) is one of the most investigated brain regions on exercise due to its relationship with maintaining exercise. This study aims to demonstrate the effects of a high-intensity exercise on cerebral hemodynamic parameters in the PFC and how physical load reflects on PFC. Methods. - Twelve male (mean +/- SD: age = 20 +/- 1.56 years) performed the Wingate Anaerobic Test (WAnT; 30-s all-out) for three repetitions as a Sprint Interval Training (SIT) exercise model via a cycling ergometer with 4 min of active recovery (50 W, 50 rpm) between the repetitions. A functional Near-infrared Spectroscopy (fNIRS) device was used to record hemodynamic changes of the prefrontal cortex throughout the entire protocol. Results. - The oxy-hemoglobin (oxy-Hb) and total-hemoglobin (total-Hb) levels in the PFC were increased significantly (P < 0.001), while the power outputs were decreased in repetitive WAnT's (P < 0.05). The oxy-Hb values were higher than the pre-exercise values even in the recovery periods between WAnT's (P < 0.001). Conclusions. - In conclusion, repeated load with the active recovery periods might be an optimal approach for increasing the PFC oxygenation to its peak values. These results suggest that a repeated Wingate test could be used as a test to improve the metabolic condition of the athlete's brain. (c) 2022 Elsevier Masson SAS. All rights reserved.
