Supports pre-exercise flow as modulator of isometric vasoconstriction; leaves open active vasodilation withdrawal in thermoregulatory models.
Does isometric handgrip exercise decrease cutaneous vascular conductance when skin blood flow is elevated by local heating?
The decrease in cutaneous vascular conductance during isometric handgrip exercise in hyperthermic conditions is associated with pre-exercise CVC levels, arguing against the withdrawal of active vasodilation as the primary mechanism.
