Aim: This study aimed to compare
the effectiveness of whole body vibration (WBV) and local vibration (LV)
exercise on counter-movement
jump performance (CMJ) and its residual characteristics in well-trained
athletes.
Material
and Methods: Thirty-two male
athletes (age: 22.3±3.2 years) visited the laboratory twice, 48 hours apart,
and performed WBV and LV in two sessions of equal duration. Each test day had
two parts (sham [0 Hz, 0 mm] and vibration treatment [50 Hz, 4 mm]), 20 min
apart. LV or WBV were applied for 6×15 sec with 1 min passive rest between
repetitions. During the LV, participants were asked to lie supine (2×15 sec)
and then lie laterally (2×2×15 sec) such that the quadriceps muscles connected
to the WBV device. WBV was applied in the squatting position at 135º knee
angle. After each session, the participants were tested for CMJ for 8 min at
the 1st, 2nd, 3rd, 4th,6th, and 8th min.
Results: The results of two-factor
repeated measures ANOVA test revealed that both WBV (p = 0.27; np2
= 0.04) and LV (p = 0.57; np2 = 0.03) and their sham
conditions decreased CMJ height to a similar extent. Further, there was no
statistically significant difference between WBV and LV at any measurement time
point (p>0.05).
