During aerobic exercise, cerebral blood flow (CBF) decreases past 70% of maximal oxygen uptake (VO2), but transient hypercapnia could mitigate the reduction. To examine effect oral (OB), nasal (NB), and combined (CB) breathing on CBF during a graded exercise test (GXT). Six young males (age: 21.8 ± 2.3 years) performed three GXTs until volitional fatigue using randomized condition (OB, NB, or CB) order. Respiratory gases were assessed via metabolic cart. Ultrasound sonography (7.5 MHz linear transducer) was utilized to assess peak systolic velocity (PSV), end-diastolic (EDV), vessel diameter internal (ICA) external (ECA) carotid artery. A one-way ANCOVA, with VO2 as covariate, followed by Bonferroni post-hoc analysis, differences between conditions. The end-tidal partial pressure CO2 (PetCO2) significantly greater (p = 0.006) NB (33.16 1.37 mmHg) than that CB (26.63 1.32 OB (26.72 1.37) at 100% VO2max. There trend PSV in ICA throughout entire GXT only 0.027) (126.12 7.51 cm/s) compared (92.47 7.34 not (111.91 7.14 GXT, demonstrated superior capacity increase CBF, denoted higher OB, which might be partly related an increased PetCO2.
