May reduce perfusion during passive stretch via sympathetic nerves; hypothesis-generating for human muscle blood flow regulation.
Does passive muscle lengthening elicit active vasomotor responses in hamster retractor muscle resistance vessels?
Passive lengthening of skeletal muscle stimulates periarteriolar sympathetic nerve activity, causing vasoconstriction and reducing blood flow.
Welsh et al. (1996) studied this question.
