Abstract/OtherAbstract:
The aims of this study were to assess the behaviour of a vibrating platform under different conditions and to compare the effects of an 8-weeks periodised training programme with whole body vibration (WBV) alone or in combination with conventional strength training.Vibrating frequencies, displacements and peak accelerations were tested through a piezoelectric accelerometer under different conditions of load and subjects' position. Eighteen national level female athletes were assigned to one of three different groups performing WBV, conventional strength training (ST), or a combination of the two (WBV+ST). Isometric maximal voluntary contraction, dynamic maximal concentric force, and vertical jump tests were performed before and after the conditioning programme.Vibrating displacements and maximum accelerations measured on the device were not always consistent with their expected values calculated from the display and manufacturers' information (sinusoidal waveforms). WBV alone or in combination with low intensity resistance exercise did not seem to induce significant enhancements in force and power when compared to ST.It appears that WBV cannot substitute parts of strength training loading in a cohort of young female athletes. However, vibration effects might be limited by the behaviour of the commercial platforms as the one used in the study. More studies are needed to analyse the performances of devices and the effectiveness of protocols.
