This study examined the acute effects of whole-body vibration (WBV) on knee joint position sense and indices of neuromuscular function, specifically strength, electromechanical delay and rate of force development. Electromyography and electrically evoked contractions were employed to investigate neural and contractile responses to WBV. Fourteen healthy males completed two treatment conditions on separate occasions: (1) 5 x 1 minute of unilateral isometric squat exercise on a synchronous vibrating platform [30 Hz, 4 mm peak-to-peak amplitude] (WBV); (2) a control condition (CON) of the same exercise without whole-body vibration. Knee joint position sense (joint angle replication task), and quadriceps neuromuscular function were assessed pre-, immediately-post and lh post-exercise. During maximum voluntary knee extensions peak force (PFV), electromechanical delay (EMDV), rate of force development (RFDV) and EMG of the quadriceps were measured. Twitch contractions of the knee extensors were electrically-evoked to assess EMDE and RFDE. Results showed no influence of WBV on knee joint position sense, EMDV; PFV and RFDV during the initial 50, 100 or 150 ms of contraction. Similarly, electrically-evoked neuromuscular function and neural activation remained unchanged following the vibration exercise. A single session of unilateral WBV did not influence any indices of thigh muscle neuromuscular performance or knee joint proprioception.
