摘要本研究旨在探讨全身振动对下蹲运动中股外侧肌氧合的影响。18名男性受试者[平均年龄，27.3 ± 6.0（SD）岁;平均身高，171.8 ± 4.9 cm;平均体重，64.4 ± 6.1 kg]在振动平台上进行了3 min（有振动和无振动）下蹲运动，并通过近红外光谱测定股外侧肌氧合的变化。肌肉氧合水平和总血红蛋白和肌红蛋白水平（总Hb/Mb）下降，在蹲运动与振动。运动后，肌肉氧合水平和总Hb/Mb从运动过程中的最低值迅速增加，并在随后的10 min内保持不变。在开始蹲起运动后90 ~ 180 s，有振动的肌肉氧合水平显著低于无振动的肌肉氧合水平。从下蹲运动后90 s到540 s，振动组总Hb/Mb显著高于无振动组。本研究表明，WBV运动影响股外侧肌的氧合水平，并降低肌肉氧合水平相比，没有WBV。因此，WBV运动可能是一种有效的肌肉脱氧训练刺激。
The purpose of this study was to investigate the effects of whole body vibration (WBV) on oxygenation of vastus lateralis muscle during squatting exercise. Eighteen male subjects [mean age, 27·3 ± 6·0 (SD) years; mean height, 171·8 ± 4·9 cm; mean weight, 64·4 ± 6·1 kg] performed squatting exercise on a vibration platform for 3 min with and without vibration, and changes in oxygenation of the vastus lateralis muscle were determined by near‐infrared spectroscopy. The muscle oxygenation levels and total haemoglobin and myoglobin levels (total Hb/Mb) decreased during squatting exercise with and without vibration. After exercise, the muscle oxygenation level and total Hb/Mb rapidly increased from the minimum value during exercise and remained constant for latter 10 min. The muscle oxygenation levels with vibration from 90 to 180 s after the start of squatting exercise were significantly lower than those without vibration. Total Hb/Mb with vibration from 90 s after the squatting exercise to 540 s were significantly higher than those without vibration. This study demonstrated that WBV exercise affects the oxygenation level of vastus lateralis muscle and reduces muscle oxygenation level compared to that with no WBV. Therefore, WBV exercise may be an efficient training stimulus for muscle deoxygenation.
