Figure Lengend Snippet: A and B: normalized (i.e., zeroed to baseline) group average data for deoxygenated hemoglobin (HHb) and total hemoglobin (THC), respectively, presented as 5-s intervals with associated 95% between-participant confidence interval bands. C: an exemplar participant’s blood velocity through the middle cerebral artery (BV; cm/s) via transcranial Doppler (TCD). Light and dark gray rectangles depict the durations of an exercise warm-up and intervention (i.e., exercise and hypercapnia), respectively.
Article Snippet: For the hypercapnic, exercise, and control conditions, transcranial Doppler ultrasound (TCD) (Neurovision 500M, Neurovision TOC2M; Multigon Industries, Elmsford, CA) and near-infrared spectroscopy (NIRS) (Oxiplex TS, model 92505; ISS, Champaign, IL) probes were used to measure 1 ) blood velocity through the middle cerebral artery (BV), 2 ) absolute cerebral deoxygenated hemoglobin (HHb), and 3 ) total hemoglobin concentrations (THC), measures that provide a valid proxy for a direct measure of CBF ( Bishop et al. 1986 ; Madsen and Secher 1999 ).
