The Hand and Environment

―Physiological Changes of Skin Temperature, Vibratory Sensibility and Pinch Strength of the Hand and Oxygen Uptake in Two Climatic Conditions―

Abstract

Digital temperatures, pinch strengths, vibratory sensibilities, and oxygen uptakes of 21 healthy male adults in two age groups and under two climatic conditions were studied and compared. 1) The digital temperatures of the older age group were always a little higher than those of the younger age group. 2) Pinch strengths became slightly weakened in the 30℃ chamber. 3) Vibratory sensibilities at 125 Hz became slightly sensitive in the 30℃ chamber. 4) Oxygen uptakes were greater in the 10℃ chamber.
