Abstract: : The aim of the present study was to evaluate the vibration transmission from a vibration platform through vectran cables to the upper body and its relationship to induced muscular activation.Fifteen clinically healthy participants performed 3 different arm exercises - biceps curl, triceps curl, and lateral raise. Vibration transmission to the upper body was assessed over a wide range of accelerations (from 1.90 to 5.98 g) and frequencies (from 25 to 40 Hz). To assess the vibration transmission, seven tri-axial accelerometers were attached from the hand up to the head and the root-mean-square (RMS) of acceleration signal of each site-specific body point was calculated. Muscular activity of biceps brachii, triceps brachii, deltoid and upper trapezius was recorded.The results showed a significant attenuation of the platform accelerations transmitted through the vectran cables to the upper body. Handle vibration ranged between 27 - 44 % of the acceleration delivered by the platform depending on platform vibration parameters (acceleration/frequency). Vibration increased the muscle activity of biceps brachii, triceps brachii, deltoid and upper trapezius muscles significantly only during biceps curl exercises. No frequency and/or acceleration effect was found on the size of the muscle response.The results of the present study suggest that a cable-pulley resistance system on a vibration platform channels the vibration safely from the platform to the arms and induces additional muscle activation in some arm muscles when biceps curl exercises are performed.
