Methods: Twelve college males (age, 22.3 ± 1.9 yrs; height, 174.8 ± 6.1 cm; weight, 68.5 ± 5.3 kg) were voluntarily participated in this repeated measures designed and balanced ordered study. All subjects were asked to squat 6-min on the vibration platform with 10-min rest intervals in a sitting position to randomly perform three treatments, low (10 Hz), medium (30 Hz) and high (50 Hz) frequencies of WBV with different amplitudes (0.4 and 2 mm). During the treatments, the V ‧O2 and La were measured by CORTEX metabolic analysis system and Lactate ProTM. The beat-to-beat heart rates were also assessed by Polar heart rate monitor and HRV analysis software during the WBV. The differences between mean values were tested by repeated measures one-way analysis of variance (ANOVA). Results: The HR, LA, V ‧O2, BP, and HRV were significantly different from the baseline values (p< .05). However, there were no significant differences on the HR, LA, V ‧O2, BP, and HRV among either the different amplitudes or frequencies of WBV treatments. The total average V ‧O2 and LA during the WBV were 15.20 ± 0.69 ml/kg/min and 4.1 ± 0.3 mmol/L, respectively. Regardless of the high or low amplitudes, the mean arterial pressures (MAP) in 10 Hz WBV were significantly higher than the baseline. The CCVLF (coefficient of component variance of low frequency power in HRV) in the 10 Hz and 30Hz with the different amplitudes were significantly lower than the baseline, but not in the 50 Hz. Conclusion: The different frequencies (10, 30, 50 Hz) and amplitudes (0.4 and 2 mm) of WBV could induce similar physiological responses, however, the WBV was a low intensity exercise. Nevertheless, the low frequency (10 Hz) and amplitude (0.4 mm) of WBV might increase the cardiovascular stresses.自律神經系統副作用振動運動autonomic nervous systemside effectsvibration
