Résumé / Abstract

Vibration exercise (VbX) is a new type of physical training to increase muscle power. The present study was designed to assess the influence of whole-body VbX on metabolic power. Specific oxygen uptake (sVO2) was assessed, testing the hypotheses that sVO2 increases with the frequency of vibration (tested in 10 males) and with the amplitude (tested in 8 males), and that the VbX-related increase in sVO2 is enhanced by increased muscle force (tested in 8 males). With a vibration amplitude of 5 mm, a linear increase in sVO2 was found from frequencies 18 to 34 Hz (p<0.01). Each vibration cycle evoked an oxygen consumption of approximately 2.5 μl × kg-1. At a vibration frequency of 26 Hz, sVO2 increased more than proportionally with amplitudes from 2.5 to 7.5 mm. With an additional load of 40% of the lean body mass attached to the waist, sVO2 likewise increased significantly. A further increase was observed when the load was applied to the shoulders. The present findings indicate that metabolic power in whole-body VbX can be parametrically controlled by frequency and amplitude, and by application of additional loads. These results further substantiate the view that VbX enhances muscular metabolic power, and thus muscle activity.
