Whole Body Vibration at Different Exposure Frequencies: Infrared Thermography and Physiological Effects

Table 1

Mean and standard deviation (±SD) for all 24 subjects before and after 15 minutes of WBV exposure. The values are for physiological measurements such as blood pressure, axillary temperature, heart rate, and respiratory rate, measured at 4 different frequencies of WBV (, , , and  Hz) ().
