摘要

目的：探討低頻率 (8 Hz) 不同振幅振動運動 (whole-body vibration, WBV) 對衰竭運動後生理恢復之影響。方法：21名大學男性學生（年齡，20.4±2. 6歲；身高，175.7± 5.8 cm；體重，71.3±6.9 kg）自願參加本重覆量數實驗設計之研究，且須於衰竭性腳踏車運動後，分別接受三種10分鐘的實驗處理，包括無振動運動 (0 Hz, 0 mm, Con) 、高振幅 (8 Hz, 4 mm, HAT) 與低振幅振動運動 (8 Hz, 1 mm, LAT)。所有受試者坐在振動平臺上10分鐘。隨後，所有受試者以仰臥姿安靜休息1小時。在實驗處理與恢復期時，檢測攝氧量 (VO2) 、運動後過攝氧量 (EPOC) 、心跳率 (HR) 與血乳酸 (La)。結果：HR、La以及EPOC在三種不同振幅振動運動處理間，皆未達顯著差異。不過，絕對與相對的攝氧量，在WBV處理時，HAT明顯高於Con與LAT（絕對攝氧量，Con vs. HAT vs. LAT, 0.578 ± 0.075 vs. 0.693 ± 0.132 vs. 0.568 ± 0.068 L/min, p < .05；相對攝氧量，Con vs. HAT vs. LAT, 8.21 ± 1.18 vs. 9.76 ± 1.84 vs. 8.00 ± 0.90 ml/kg/min, p < .05）。結論：不管高或低的振幅，低頻率 (8 Hz) 的全身振動運動均無法改善衰竭性運動後之生理恢復。不過，在衰竭性腳踏車運動後，高振幅振動運動的介入仍會增加能量消耗。

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.
