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).
Conclusion: WBV and LV were not effective methods to enhance the CMJ performance of well-trained athletes. However, WBV platform can be safely used as LV exercise equipment since no adverse effect was observed.
