Description of the whole body vibration exercise protocols.

Study	Type of the OVP	Frequency (Hz)	Amplitude/PPD (mm)	Position	Sessions/sets	Sets/Time series/ rest between series
Menéndez et al., 2016	Not informed	10	PPD 5	Seated on wheelchairs with the feet on the OVP	Single session.	10 × 1min/1min
Johnson et al., 2014	Alternating	26	Amplitude 2	Squat with knees flexed 30 to 40°.	Single session.	10 × 30 s/1min
Sañudo et al., 2013	Alternating	12-16	PPD 4	Eight different dynamic and static exercises (lunge, step up and down, squat, calf raises, left and right pivot, shoulder abduction with elastic bands, shoulder abduction with elastic bands while squatting, arm swinging with elastic bands	3 sessions/wk – 12 wks.	8 × 30-60 s / 30 s
Lohman et al., 2014	Synchronous	50	PPD 5-6	Subject stands supported with one foot on the vibration platform for 10 min.	Single session.	10 bouts × 60s/ 2 s
Herrero Et al., 2011a	Alternating	10-30	PPD 5	Subject was laid down and fixed to a tilt table with straps (60º knee flexion -0º the full knee extension). Tilt table was placed at 45º and the subject was kept in that position for a period of 10 min before the WBV.	Eight sessions in 3 wks.	3 min continuous (constant) or fragmented (three bouts 60s exposures, separated by 60 s rests).
Herrero et al., 2011b	Alternating	10-30	PPD 5	Same as above (Herrero et al,33)	Eight sessions in 3 wks.	3 min continuous (constant) or fragmented (three bouts 60s exposures, separated by 60 s rests).
Lythgo et al., 2009	Alternating	5-30	Amplitude 2.5-4.5	Squat position (50° of knee flexion).	Single session.	14 × 1-min and 2 × 1 min bouts where no vibration was applied.
Lohman et al., 2007	Synchronous	30	Amplitude 5-6	Isometric hold with Knees bent at 25°, 80° or at 100°	Single session.	3 × 60 s (180 s).

min – minute, PPD – peak-to-peak displacement, s – second, WBV- whole body vibration, WBVT- Whole body vibration training, wks - weeks
