Summary over the last two decades, the use of vibration as a complementary means of physical exercise has increased significantly. Scientific literature shows different positive effects, although most trials have focused on the analysis of the squat exercise. The objective of this study was to analyse muscle activity of rectus abdominis and transmission of vibration in the human body during the realisation of a front bridge over an oscillating vibration platform by vibrating at different frequencies (5, 16.20 Hz) and at a constant amplitude (3 mm). Maximum head accelerations (X, Y, Z axes) and average electromiographic activity of rectus abdominis were determined in 31 healthy subjects by means of a triaxial accelerometer and surface electromiography. For each axle, a damping coefficient was calculated by subtracting the maximum acceleration recorded on the head from the maximum acceleration recorded on the platform. The electromiographic activity of the rectus abdominis and the damping coefficients in the X and Z axes increased significantly with each increase in the platform vibration frequency (p < 0.001). It is concluded that the front bridge over vibratory platform at frequencies of 16-20 Hz is an effective exercise to recruit the muscle fibres of rectus abdominis in the student population. AbstractWhole-body vibration exercise have been wisely used during the last two decades, with most scientific publications various reporting effects. Most commonly, squat exercises have been studied. Instead, this study explored the rectus abdominis activity and the transmission of sinusoidal vibration to the human body during the performance of front bridges on a oscillating vibration platform at different frequencies (5, 16.20 Hz) with constant Amplitude (3 mm). Maximal vibration-induced acceleration at the head (axis X, Y, Z) and mean electromyographic activity were assessed in thirty-one healthy pressures using a skin-led triaxial accelerometer and surplus electromyography. A damping cost-efficient was calculated for each axis as the difference between platform and head maximal accelerations. Rectus abdominis activity and the occurrence of losses in the axis X and Z significantly increased with each increase in the platform vibration frequency (p < 0.001). It is concluded that a front bridge on an oscillating vibration platform vibrating at 16-20 Hz is effective to Activate meaningful the rectus abdominis MUSCLES in the surveyed population. http://dx.doi.org/10.5232/ricyde2012.02802
