Effects of endurance exercise on physiologic complexity of the hemodynamics in prefrontal cortex.

This research paper explores the effects of endurance exercise and the intake of hydrogen gas on the complexity of hemodynamics in the prefrontal cortex (PFC). The study involved 24 healthy young men who completed endurance cycling exercise at different physical loads after either taking hydrogen gas or a placebo. The complexity of the PFC hemodynamics was measured using functional near-infrared spectroscopy (fNIRS) and quantified using multiscale entropy. The results showed that the fNIRS complexity was significantly greater during exercise compared to baseline, and the intake of hydrogen gas further increased the complexity. The study suggests that fNIRS complexity could be a marker for the adaptive capacity of the PFC to endurance exercise and interventions. [Extracted from the article]
