The effect of local acclimatization to cold on the intensity of vasomotor reaction caused by locally applied vibration.

In two groups of men, acclimatized or non-acclimatized locally to cold, hand skin temperature and the arterial blood pressure were measured during exposure to locally applied vibration of strictly defined parameters. It was found that in acclimatized subjects the intensity of vasomotor response was smaller than in non-acclimatized ones. The results obtained indicate that local acclimatization to cold may be a factor alleviating the action of locally applied vibration on the peripheral vascular system.
