Objectives: To determine the acute effects of different static and dynamic whole body vibration on vertical jump performance in male collegiate students. Methods: Fifteen male students (Mean; age: 25±5 years, height: 175±10 cm, weight: 70±20 kg) volunteered to participate in this study. The participants completed three different treatments (control, static and dynamic) followed the balance order design. The control treatment, participants stood on vibrating platform in squat position (120° of knee angle) without vibration. Under static treatment, they performed with the same schedule of control treatment but the vibration was with a frequency and amplitude of 30 Hz and 2 mm respectively. Under dynamic treatment, they stood on vibrating platform in dynamic squat position (90°↔160° of knee angle) with the vibration was with a frequency and amplitude of 30 Hz and 2 mm respectively. The whole body vibration treatment included three sets of 40-second vibrations with a 30-second rest in between. The two test sessions (countermovement jump and squat jump) were performed before and after vibration treatment. The data were analyzed using SPSS version 20 and the dependent two way ANOVA statistical method. All values were reported as means ± standard deviation (SD), significant level was set at α of .05. Results: The results showed there was a significant interaction effect (treatments × pre-post test) of enhanced countermovement jump height (F2,28 = 7.116, p < .05) and squat jump height (F2,28 = 4.325, p < .05) parameters following whole body vibration. There was no significant interaction effect for rate of force development following the three different whole body vibration treatments. Conclusions: We concluded that the acute dynamic WBV exercise could be used for enhancing the human performance, especially in vertical jump height. On the other hand, the rate of force development was no change for all the WBV treatment.
