The purpose of this study was to examine the acute effect of a single bout of whole body vibration (WBV) on flexibility and explosive strength of lower limbs in young artistic gymnasts. Thirty-two young competitive gymnasts volunteered to participate in this study, and were allocated to either the vibration group or traditional body weight training according to the vibration protocol. The vibra...

Effects of whole-body vibration (WBV) exposure on professional drivers were predicted using a 45 subjects sample of healthy volunteers from both genders. These volunteers preformed a visual/motor accuracy evaluation test, the 'omega test', inside a vehicle (van) under three different WBV exposure conditions, van halted, van performing a circuit on asphalt, and on cobblestone. WBV levels of the ...

This paper analyzes the reason of Low-speed vibration in an electric vehicle, builds the mathematical equation of powertrain torsional vibration. Then, the model of torque ripple considering non-sinusoidal magnetic field distribution is built, orders and frequencies of torque ripple in PMSM is predicted. According to the relationship between the torsional vibration in low-speed of the electric ...
