摘要：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;np 2 = 0.04) and LV (p = 0.57;np 2 = 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.
