碩士 === 國立臺灣師範大學 === 運動競技學系 === 98 === Purpose: This study was to investigate the effects of the different amplitudes of whole-body vibration (WBV) with low frequency (8 Hz) on the physiological recovery from the exhaustive exercise. Methods: Twenty-one college males (age, 20.4 ± 2.6 yrs; height, 175.3 ± 3.5 cm; weight, 71.3 ± 6.9 kg) were voluntarily participated in this repeated measures designed study and were asked to respectively perform three 10-min treatments, non-vibration (0 Hz, 0 mm, Con), high (8 Hz, 4 mm, HAT) and low (8 Hz, 1 mm, LAT) amplitudes of WBV, after incremental exhaustive cycling exercises. During the 10-min treatments, all subjects sat on a chair on the vibration platform, and then were asked to rest in supine position during the 1-h recovery phase. The oxygen consumptions (V ‧O2), excess post-exercise oxygen consumption (EPOC), heart rates (HR) and blood lactate levels (La) were measured during the treatments and recovery phases. Results: There were no significant differences on the HR, La and EPOC among the three treatments. However, the absolute and relative V ‧O2 during the WBV treatment in the HAT were significantly higher than those in the Con and LAT (absolute V ‧O2, Con vs. HAT vs. LAT, 0.578 ± 0.075 vs. 0.693 ± 0.132 vs. 0.568 ± 0.068 L/min, p < .05; relative V ‧O2, Con vs. HAT vs. LAT, 8.21 ± 1.18 vs. 9.76 ± 1.84 vs. 8.00 ± 0.90 ml/kg/min, p < .05). Conclusion: Regardless of the high or low amplitudes, the low frequency whole-body vibration (8Hz) could not improve the physiological recovery from exhaustive exercise. However, the high amplitude WBV still increased the energy expenditures even after the intense cycling exercise.
