Key result
Static handgrip exercise increased regional cerebral blood flow in hand sensorimotor (9%), insular (7-8%), and anterior cingulate (6%) regions compared to post-exercise cuff occlusion.
Why the study?
Does central command during static handgrip exercise activate regions of the insular cortex independent of muscle metaboreflex activation and blood pressure elevations?

Supports insular role in exercise autonomic control; leaves open clinical translation to HF or hypertension.

Central command during handgrip exercise activates regions of the insular and anterior cingulate cortices independent of metaboreflex activation and blood pressure elevation.
Williamson et al. (2003) studied this question. Static handgrip exercise (SHG) vs. post-SHG exercise cuff occlusion (PECO) was evaluated on regional cerebral blood flow (rCBF). Static handgrip exercise increased regional cerebral blood flow in hand sensorimotor (9%), insular (7-8%), and anterior cingulate (6%) regions compared to post-exercise cuff occlusion.
