Relationship among vibration-induced relative changes in peak torque during maximal voluntary contraction (MVC, A–C) of plantar flexion or rate of torque development from the onset to 0–100 ms (RTD, D) and neural variables [root mean square of the electromyogram (RMS-EMG), voluntary activation (VA%), V-wave] of the medial gastrocnemius (MG) for young men. Data of older men were not included because no significant changes were shown for MVC and RTD after the vibration.
