چکیده انگلیسی
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 1â¯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%, pâ¯<â¯0.05). SOL (â13%, pâ¯<â¯0.05) and TA (â6%, pâ¯<â¯0.05) activities were significantly reduced; co-contraction tended to be diminished (â8%, pâ¯=â¯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.
