This paper relates is the result of a research collaboration with an Italian group and presents some preliminary findings on WBV in isolation or combined with strength training in female athletes. the most important findings relate to the behaviour of the WBV platform used in this study and the limitations in using such devices for performing strength training exercises with additional mass. Needless to say that more studies are needed with larger sample sizes to improve our understanding of the effectiveness of vibration exercise.

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
