  • Title: Acute whole-body vibration increases reciprocal inhibition.
    Author: Ritzmann R, Krause A, Freyler K, Gollhofer A.
    Journal: Hum Mov Sci; 2018 Aug; 60():191-201. PubMed ID: 29957423.
    Abstract:
    Based on previous evidence that whole-body vibration (WBV) affects pathways involved in disynaptic reciprocal inhibition (DRI), the present hypothesis-driven experiment aimed to assess the acute effects of WBV on DRI and co-contraction. DRI from ankle dorsiflexors to plantar flexors was investigated during submaximal dorsiflexion before and after 1 min of WBV. With electromyography, musculus soleus (SOL) H-reflex depression following a conditioning stimulation of the peroneal nerve (1.1x motor threshold for the musculus tibialis anterior, TA) was assessed and co-contraction was calculated. After WBV, DRI was significantly increased (+4%, p < 0.05). SOL (-13%, p < 0.05) and TA (-6%, p < 0.05) activities were significantly reduced; co-contraction tended to be diminished (-8%, p = 0.05). Dorsiflexion torque remained unchanged. After WBV, DRI increased during submaximal isometric contraction in healthy subjects. The simultaneous SOL relaxation and TA contraction indicate that a more economic movement execution is of functional significance for WBV application in clinical and athletic treatment.
