The Effect of Whole-Body Vibration on Jump Height and Active Range of Movement in Female Dancers

Abstract Background Patellofemoral pain (PFP) is the most prevalent orthopedic problem in active young adults. Due to its multifactorial etiology, a variety of therapeutic measures have been adopted to treat PFP, including exercise therapy, electrotherapy, and manual therapy. It has also been suggested that whole body vibration (WBV) can improve neuromuscular function in persons with knee problems. The aim of the present study was to evaluate the effects of adding WBV to routine exercise programs on flexibility, vertical jump height, agility and pain in athletes with PFP. Methods Twenty-four male athletes with PFP were randomized into two groups of WBV + exercise (n = 12) or exercise only (n = 12). Participants received their interventions during 4 consecutive weeks (12 sessions). Pain intensity, flexibility and agility were assessed respectively as score on a numerical rating scale, the sit-and-reach test, and a modified T-test, and vertical jump height was measured to the nearest centimeter. The tests were done before and after the interventions, and the results were compared between the two groups. Independent t-tests and paired t-tests were used for between- and within-group comparisons, respectively. Results After the interventions, all variables for vertical jump height, flexibility, agility and pain intensity improved significantly in both groups (p < 0.05). The flexibility test showed significantly greater improvement in the WBV + exercise group (p<0.001), whereas for vertical jump height, agility and pain intensity, there were no statistically significant differences between groups (p>0.05). Conclusions The present findings showed that exercise therapy with and without WBV can significantly decrease pain and increase agility, vertical jump height and flexibility in athletes with PFP. Adding WBV to routine exercise therapy, however, can augment the effects of the latter on flexibility. Trial registration IRCT, IRCT20090831002391N39.

Abstract BackgroundWhile many studies suggested the effects of plyometric and whole-body vibration exercises on post-activation potentiation, few studies have compared the acute effects of plyometric and whole-body vibration on the occurrence of post-activation potentiation. Therefore, this study aimed to compare the acute effects of plyometric and whole-body vibration exercises on postactivation potentiation in collegiate basketball players.MethodsTwenty-four collegiate basketball players (Age 20.8 ± 2.02 Y, height 1.79 ± 0.7 m, weight 71.2 ± 7.6 kg, and body mass index 22.00 ± 1.49 kg/m2) participated in this randomized crossover study. Subjects were received both plyometric and whole-body vibration exercises after 48-hour washed-out period. Countermovement Jump height, sprint, and agility time were measured at baseline, 4- and 12-minute post-plyometric and whole-body vibration exercises. ResultsThe result suggests a positive effect of both the plyometric and whole-body vibration exercises on countermovement jump and agility time (p = 0.001). While the countermovement jump height and agility were higher in the plyometric group (mean difference 1.60 cm and 0.16 sec, respectively), the sprint performance was higher in the whole-body vibration group (mean difference 0.28 sec). However, these differences were statistically nonsignificant between the two groups (p > 0.05 ).ConclusionsThis study suggests that both plyometric and whole-body vibration exercises may improve postactivation potentiation, which leads to a better physical performance.Trial registrationCTRI/2019/05/019059.
