Exhaustive Exercise Attenuates the Neurovascular Coupling by Blunting the Pressor Response to Visual Stimulation

Table 1

The heart rate (HR), mean arterial pressure (MAP), arterial partial pressure of carbon dioxide (CO₂), and the posterior cerebral artery blood flow velocity (PCAv) during the rest, exercise, and recovery periods.

	Rest	Exercise period		Recovery
		5 min	Exhaustion
HR (bpm)	69.9 ± 2.5	151.9 ± 4.3^*	173.4 ± 4.4^*	117.8 ± 3.5^*
MAP (mmHg)	87.5 ± 4.0	112.9 ± 5.6^*	98.3 ± 4.9^*	85.4 ± 3.6
CO2 (mmHg)	37.2 ± 1.1	42.0 ± 1.1^*	34.3 ± 0.9^*	32.9 ± 1.1^*
PCAv (cm/s)	32.2 ± 1.9	36.2 ± 2.6^*	27.9 ± 2.1^*	26.1 ± 1.5^*

The data are presented as the mean ± SE values, versus rest.
