Title Suppressive mechanism of gastric motility by whole-body vibration
Bibliographic information Oct. 1999, Vol.72, No.7, p.469-474. Illus. 21 ref.
Abstract Gastric motility suppression due to exposure to whole-body vibration (WBV) was evaluated by electrogastrography (EGG) in ten healthy volunteers. The amplitude of EGG wave and the power spectrum corresponding to the slow wave component was remarkably decreased by vibration exposure. Food intake enhanced gastric motility about 2.5-fold in the power spectral density. During and after vibration exposure, the response mode was similar to those in fasting states. Anticholinergic and alpha-adrenergic blocking agents decreased the power spectra. A further decrease was observed during vibration exposure. A beta-adrenergic blocking agent led to a marked increase in the amplitude of EGG and its power spectrum. However, pretreatment with a beta-adrenergic blocking agent resulted in a reduction of EGG amplitude and power spectrum on exposure to vibration. Results suggest that short-term exposure to WBV can suppress gastric myoelectric activity, the responses of which may be mediated by neurohumoral effects as well as by the mechanical effect of WBV.
