The effect of different vibration frequencies in the skin temperature in healthy subjects

This study assessed the impact of acute exposure to whole-body vibration in skin temperature of the lower limbs in healthy subjects. Twelve healthy volunteers (mean age 24.55 years) were randomly assigned to two groups and were exposed to different whole-body vibration protocols (35 Hz and 40 Hz frequency and 5-6 mm amplitude). Skin temperature was measured before and immediately after exposure. Infrared thermography measurements revealed that skin temperature decreased significantly after exposure to vibration. The results were different for both vibration frequencies. Exposure to 35 Hz vibration produced significant decreases in skin temperature in some of the studied regions of interest and exposure to 40 Hz vibration produced significant decreases in skin temperature in all studied regions of interest.
