Abstract |
|
Whole-Body Vibration (WBV) is a
new form of neuromuscular training that seems to improve muscular
performance. The aim of this study was to examine the acute effects of
WBV on vertical jumping ability. Sixteen physically active young women
volunteered to participate in the research (20.59±1.9 years old)
performing two different protocols (vibration protocol and control
protocol). During both interventions, participants were standing at an
upright position, maintaining their knees semi-flexed on a vibrating
platform (Galileo Fitness) for 6min, at a fixed frequency of 25Hz and an
amplitude of 8mm, while in the control protocol no vibration was
performed. For the evaluation of the vertical jumping ability, the squat
jump (SJ) and the counter-movement jump (CMJ) tests were used and were
performed on a force platform (Bertec). The measurements were set
before, post and 15 min after the completion of the protocol. The
subjects executed each vertical jump three times and the best
performance was recorded. A two-way (protocol x measurement, 2x3)
analysis of variance (ANOVA), with repeated measures on both factors,
was used to examine the effects of WBV on vertical jumping ability.
Tukey’s post-hoc pairwise analyses were used when appropriate. The
results revealed no statistical interaction between the factors
“protocol” and “measurement” for both jumps (SJ and CMJ). The
performance on the SJ during the three measurements, before, post, after
15min, was 20.47±2.9, 20.46±2.7 and 19.75±2.9cm for the vibration
protocol and 20.06±2.5, 19.4±3.0 and 19.15±2.8cm for the control
protocol. Similarly, for the CMJ the performance during the three
measurements was 21.73±2.7, 21.23±3.0 and 21.4±3.0cm for the vibration
protocol and 21.5±2.6, 20.72±3.0 and 20.53±3.0 cm for the control
protocol. Conclusively, it appears that WBV does not affect the vertical
jumping ability of young women. |
