    Input: INTRODUCTION The preconditioning of divers to reduce  post-dive decompression sickness ( DCS )  has gained increased interest in diving medical research over the last few years . The beneficial effects of physical exercise , oxygen breathing , hyperbaric exposure , heat exposure , hyperhydration , or nitroglycerin administration before the dive are only a few examples of ongoing research . In this work , we investigated the effects of pre-dive whole-body vibration on post-dive bubble formation . METHODS Following French Navy st and ard dive procedures , 14 healthy male military divers performed 2 identical dives 1 wk apart to 30 m of seawater ( msw ) for 30 min . One of the dives was r and omly preceded by a 30-min whole-body vibration session ( frequencies 35 - 40 Hz ) 1 h before the dive . Post-dive bubbles were measured precordially 30 , 60 , and 90 min after the dive and were grade d according to the Kissman Integrated Severity Score ( KISS ) protocol , with and without knee flexing . Arterial endothelial function was measured before and after vibration using flow mediated dilation ( FMD ) measurement . RESULTS A significant reduction in bubble scores was observed after the " vibration " dive . CONCLUSION As there was no observed change in FMD after vibration , we do not believe a nitric oxide mediated mechanism is involved ; rather , a mechanical dislodgement or enhanced lymphatic elimination of gas nuclei is hypothesized The purpose of this study was to investigate the effect of whole body vibration ( WBV ) training on maximal strength , squat jump , and flexibility of well-trained combat athletes . Twelve female and 8 male combat athletes ( age : 22.8 ± 3.1 years , mass : 65.4 ± 10.7 kg , height : 168.8 ± 8.8 cm , training experience : 11.6 ± 4.7 years , training volume : 9.3 ± 2.8 hours/week ) participated in this study . The study consisted of three sessions separated by 48 hours . The first session was conducted for familiarization . In the subsequent two sessions , participants performed WBV or sham intervention in a r and omized , balanced order . During WBV intervention , four isometric exercises were performed ( 26 Hz , 4 mm ) . During the sham intervention , participants performed the same WBV intervention without vibration treatment ( 0 Hz , 0 mm ) . H and grip , squat jump , trunk flexion , and isometric leg strength tests were performed after each intervention . The results of a two-factor ( pre-post[2 ] × intervention[2 ] ) repeated measures ANOVA revealed a significant interaction ( p = 0.018 ) of pre-post × intervention only for the h and grip test , indicating a significant performance increase of moderate effect ( net increase of 2.48 % , d = 0.61 ) after WBV intervention . Squat jump , trunk flexion , and isometric leg strength performances were not affected by WBV . In conclusion , the WBV protocol used in this study potentiated h and grip performance , but did not enhance squat jump , trunk flexion , or isometric leg strength in well-trained combat athletes This study aim ed to compare the effect of local vibration ( LV ) and whole body vibration ( WBV ) on lower body flexibility and to assess whether vibration treatments were more effective than traditionally used static and dynamic stretching methods . Twenty-four well-trained male combat athletes ( age : 22.7 ± 3.3 years ) performed four exercise protocol s – LV ( 30 Hz , 4 mm ) , WBV ( 30 Hz , 4 mm ) , static stretching ( SS ) , and dynamic stretching ( DS ) – in four sessions of equal duration 48 hours apart in a r and omized , balanced order . During a 15-minute recovery after each protocol , subjects performed the st and and reach test ( S&R ) at the 15th second and the 2nd , 4th , 6th , 8th , 10th and 15th minute . There was a similar change pattern in S&R scores across the 15-minute recovery after each protocol ( p = 0.572 ) , remaining significantly elevated throughout the recovery . A significant main protocol effect was found for absolute change in S&R scores relative to baseline ( p = 0.015 ) . These changes were statistically greater in LV than WBV and DS . Changes in  SS were not significantly different from LV , but were consistently lower than LV with almost moderate effect sizes . After LV , a greater percentage of subjects increased flexibility above the minimum detectable change compared to other protocol s. Subjects with high flexibility ( n = 12 ) benefited more from LV compared with other methods ( effect size ≥ 0.862 ) . In conclusion , LV was an effective alternative exercise modality to acutely increase lower extremity flexibility for well-trained athletes compared with WBV and traditional stretching exercises Wyon , M , Guinan , D , and Hawkey , A. Whole-body vibration training increases vertical jump height in a dance population . J Strength Cond Res 24(3 ) : 866 - 870 , 2010-Whole-body vibration ( WBV ) training has gained popularity with the strength and conditioning environment . Previous research reported improvements in strength and power after WBV interventions in untrained individuals with little hypertrophical development of the muscles , suggesting that the improvements are because of neuromuscular adaptations . The present intervention study recruited moderately trained individuals that have jumping as integral to their training . Participants were r and omly allocated to an intervention or control group . The intervention group was exposed to WBV at 35 Hz for 5 minutes twice a week , whereas the control group was exposed to a similar isometric contraction stress . Results indicated that after a 6-week intervention , vertical jump height increased significantly ( p < 0.05 ) in the intervention group than in the control group . The study concluded that WBV was able to maintain vertical jump height with very little intervention time ( 10 minutes a week ) and therefore should be considered as an intervention form for maintaining jump performance Rønnestad , BR and Ellefsen , S. The effects of adding different whole-body vibration frequencies to preconditioning exercise on subsequent sprint performance . J Strength Cond Res 25(12 ) : 3306–3310 , 2011—The phenomenon postactivation potentiation can possibly be used to acutely improve sprint performance . The purpose of this study was to investigate the effect of adding whole-body vibration ( WBV ) to body-loaded half-squats , performed as preconditioning activity to the 40-m sprint test . Nine male amateur soccer players performed 1 familiarization session and 6 separate test sessions . Each session included a st and ardized warm-up followed by 1 of the after preconditioning exercises : 30-seconds of half-squats with WBV at either 50 or 30 Hz or half-squats without WBV . The 40-m sprint was performed 1 minute after the preconditioning exercise . For each subject , each of the 3 protocol s was repeated twice on separate days in a r and omized order . Mean values were used in the statistical analysis . Performing the preconditioning exercise with WBV at a frequency of 50 Hz result ed in a superior 40-m sprint performance compared to preconditioning exercise without WBV ( 5.48 ± 0.19 vs. 5.52 ± 0.21 seconds , respectively , p < 0.05 ) . There was no difference between preconditioning exercise with WBV at a frequency of 30 Hz and the no-WBV condition . In conclusion , preconditioning exercise performed with WBV at 50 Hz seems to enhance 40-m sprint performance in recreationally trained soccer players . The present findings suggest that coaches can incorporate such exercise into the warm-up to improve sprint performance or the quality of the sprint training The aim of this study was to investigate the acute effects of whole-body vibration ( WBV ) on Repeated Sprint Ability ( RSA ) . Seventeen male soccer players ( 16.71±0.47 y ) performed three RSA tests ( R and omized crossover study design ) . The second RSA test was done with WBV ( RSA2 ) to assess the effect of WBV . The studied variables were : best time ( BT ) , worst time ( WT ) , total time ( TT ) , the fatigue index ( FI ) of RSA , and post-test blood lactate ( BLa ) . ANOVA with repeated measures showed no differences between RSA1 and RSA3 , while there were significant differences in all variables studied . TT= [ RSA2 0.93 % and 1.68 % lower than RSA1 and RSA3 respectively ; p<0.05 ] , BLa= [ RSA2 16.97 % and 14.73 % greater than RSA1 and RSA3 respectively ; p<0.001 ] , WT= [ RSA2 1.90 % and 2.93 % lower than RSA1 and RSA3 respectively ; p<0.01 ] , and FI = [ RSA2 30.64 % and 40.15 % lower than RSA1 and RSA3 respectively ; p<0.0001 ] . When comparing individual sprints , WBV showed a significant effect at the 5th sprint : RSA2 2.29 % and 2.95 % lower than RSA1 and RSA3 respectively ( p<0.005 ) , while at the 6th sprint : RSA2 2.75 % and 4.09 % lower than RSA1 and RSA3 respectively ; p<0.005 . In conclusion , when applying WBV during the recovery periods of Repeated Sprint Ability efforts , most of the performance variables improved
