A training intervention comparing resistance exercise with or without whole-body vibration (WBV) was conducted to compare acute and chronic effects on functional and molecular parameters.
A six-week training intervention was performed including 26 healthy males (26 years, SD=4). Two groups were analyzed in a parallel design performing either resistive exercise (RE, n=13) or resistive vibration exercise (RVE, n=13) training with weekly increasing vibration frequencies (20-40Hz). Resting and exercising blood pressure and heart rate were measured before and after the 6-week intervention.
Both training interventions decreased resting systolic blood pressure (P=0.003). Resting diastolic blood pressure was significantly decreased only in the RVE group (P=0.01). Exercising diastolic blood pressure was significantly decreased during the final training (P<0.001) with no additional effect of superimposed vibrations. Resistance exercise with superimposed vibrations evoked back pain to a higher degree than resistance exercise alone when training at frequencies above 30Hz (P<0.01).
These data suggest positive effects of resistance exercise upon cardiovascular health and vascular responsiveness and a further beneficial effect of superimposed vibrations in decreasing resting diastolic blood pressure. Finally, development of back pain may be fostered by superimposed vibrations to high training loads, particularly at higher frequencies.
进行一项训练干预，比较有或无全身振动（WBV）的抗阻运动，以比较其对功能和分子参数的急性和慢性影响。
对26名健康男性（26岁，标准差 = 4）进行了为期六周的训练干预。采用平行设计分析两组，一组进行抗阻运动（RE，n = 13）训练，另一组进行抗阻振动运动（RVE，n = 13）训练，每周增加振动频率（20 - 40Hz）。在为期6周的干预前后测量静息和运动时的血压及心率。
两种训练干预均降低了静息收缩压（P = 0.003）。仅RVE组的静息舒张压显著降低（P = 0.01）。在最后一次训练期间，运动时的舒张压显著降低（P < 0.001），叠加振动无额外影响。当训练频率高于30Hz时，叠加振动的抗阻运动比单独的抗阻运动引起背痛的程度更高（P < 0.01）。
这些数据表明抗阻运动对心血管健康和血管反应性有积极影响，叠加振动在降低静息舒张压方面有进一步的有益作用。最后，叠加振动到高训练负荷，特别是在较高频率时，可能会促进背痛的发生。
