Key result
Isometric exercise and mental stressor tasks significantly increased mean arterial blood pressure and heart rate (P<0.001) and increased regional cerebral blood flow in discrete brain regions.

Do isometric exercise and mental stressor tasks alter regional cerebral blood flow in healthy volunteers?
p-value: p=<0.001
Peripheral cardiovascular arousal induced by exercise and mental stress is associated with specific regional cerebral blood flow changes in areas implicated in cognitive and emotional behaviors.
Critchley et al. (2000) conducted an observational in Autonomic cardiovascular arousal (n=6). Isometric exercise and mental arithmetic stressor tasks vs. Corresponding control tasks was evaluated on Changes in regional cerebral blood flow (rCBF), mean arterial blood pressure (MAP), and heart rate (HR) (p=<0.001). Isometric exercise and mental stressor tasks significantly increased mean arterial blood pressure and heart rate (P<0.001) and increased regional cerebral blood flow in discrete brain regions.
