Previous research has reported no significant benefit in 30 m sprint time for international skeleton athletes who were exposed to acute intermittent synchronous VbX (30 Hz, 4 mm peak-to-peak displacement [p-p]) (Bullock et al., 2008). In a follow up study conducted by the same researchers, national female skeleton athletes were exposed to a higher vibration frequency (45 Hz) with a reduced rest period between vibration exposures (180 s to 60 s) but no sig- nificant improvement in 30 m sprint time was reported (Bullock et al., 2009).
