This study was carried out to determine the effects of frequency whole-body vibration on palmar sweating response and activity central sympathetic nervous system.Palmar volume measured right palm six healthy men before during 3 minutes exposure sinusoidal at three different frequencies (16, 31.5, 63 Hz). The had a frequency-weighted, root mean square (rms) acceleration magnitude 2.0 m/s2. As index activated system, saliva level 3-methoxy-4-hydroxyphenylglycol (MHPG) analyzed immediately after each exposure.Each induced response, that 31.5 Hz being largest. However, no significant difference found between conditions. Saliva MHPG increased in all exposures, largest change observed Hz, significant.Acute system. system were be dependent vibration.
