| Research Abstract |
This study examined physiological mechanisms of Cold-induced Vasodilation responses to local cold exposure. The results were as follows; 1) Onset time and degree of cold-induced vasodilation response were affected, respectively, by flexibility and responsiveness of blood vessels. 2) Cold-induced vasodilation response of the finger was improved by the moderate oppression on upper arm. 3) Cold-induced vasodilation response of the right finger was improved by the light cold stimulus to left finger. 4) Onset of cold-induced vasodilation response was affected by neurogenic and/or localized vascular regulation systems. 5) The mechanisms of cold-induced vasodilation response vary with individuals.
