摘要：Background and Study Aim: Exercise with vibration exposure is a type of neuromuscular training that has been used with athletes and nonathletes. The vibration is used in the development of sports performance by applying only oscillatory movements in the human body or combining those oscillations with conventional strength training exercises. No studies were found that verified the effects of applying vibration on the performance of roundhouse kick. Thus, the aim of this study was the possibility of optimising performance of kick speed and maximal isometric strength through the application of mechanical vibrations.Material and Methods: Ten taekwondo athletes (6 males and 4 females) with mean age 18.3 ±2.5 years, mean body mass 62.1 ±6.6 kg, mean height 173.3 ±7.0 cm and mean practice time 5.5 ±3.2 years volunteered to participate in this study. All the volunteers participated in two different sessions. In the sessions, they performed a warm-up, speed kick pre-test, maximal voluntary contraction (MVC) intervention (with or without vibration) and a speed kick post-test.Results: No significant differences were found between pre-test and post-test (immediately, 3, 5 and 8 minutes after intervention) for speed kick. For the force recorded during MVC with local vibration (LV), a significant difference was found between moments, during and after vibration. The force produced during LV exposure was higher compared with after vibration. However no significant difference were found between the moments after and during LV compared to MVC without LV (in corresponded moments in the given range curve), in addition, the moment after LV was higher in MVC without LV. The impulse without vibration was significant higher than impulse with vibration.Conclusions: These data suggest that training with the vibration parameters used in this present study was not able to increase the performance of speed kick (subacute) and maximal force (acute). In addition, reduced the maximal force subacutely and impulse acutely.
