Galileo Research Facts No. 110: Can Galileo Training at high frequencies increase isokinetic eccentric knee torque?

This study investigated the short-term effects of Galileo Training at (very) high frequencies of up to 40Hz on isokinetic eccentric knee torque in young health men. The study compared 3 groups: Galileo at 26 and 40Hz versus a control group performing identical exercises without vibration (10 times 60 seconds, 90° knee angle). The group at 26Hz used position 4 the one at 40Hz position 1.5 – the reason for this difference was to keep the acceleration in both groups identical. Each person performed all three training types on different days with at least 3 days of rest in-between. Pre and post measurements on each day where compared.

The Galileo groups showed higher results with significant effects in the 26Hz group compared to control with an increase of 14% and a difference vs. control of 41%. Interestingly the 40Hz group showed slightly smaller effects – even though research showed that increasing frequencies between 5 and 30Hz showed increasing muscle activation (#GRFS3, #GRFS109). There are two obvious possible explanations: one that the much smaller amplitude of the 40 Hz group (Pos. 1.5 vs. 4) limited the effects at the higher frequencies and second that there is an individual maximum frequency where no additional muscle activation can be generated by increasing frequencies – in our experience this seems to be the case depending on the individual physical abilities and age. This is one of the reasons why current Galileo devices for home use are limited to 33Hz, for Fitness use up to 36Hz and for athletes up to 40Hz, simply because not everybody will profit of the very high frequencies.
