Challenges constant cerebral perfusion assumptions during exercise; leaves open prospective validation of intensity-dependent metabolic shifts.
This review highlights that high-intensity exercise can decrease cerebral blood flow and shift brain metabolism toward lactate, challenging the traditional view of constant cerebral perfusion.
Lucas‐Cuevas et al. (2015) reported a review. Physical exercise was evaluated. Physical exercise alters cerebral blood flow, increasing it during moderate intensity and decreasing it during high intensity, while shifting brain energy metabolism from glucose to lactate.
