ABSTRACT
Backgrounds and Objectives: The Whole Body Vibration (WBV) training has been considered as a training tool for the athletes, non-athletes, elderly individuals. The aim of this study was to determine the effect of WBV training on electromyography indexes of knee extensor muscles in non-athletic girls. Materials and Methods: Twelve non-athletic student girls randomized into experimental (n=10) and control (n=10) groups. Amplitude and frequency of electrical waves related to right feet knee extensor muscles was measured in a Maximal Voluntary Isometric Contraction (MVC), one day before and after WBV training. The vibration group was treated for 4 weeks (3 times/ week) with 30 HZ frequency, 2.5 mm amplitude and in 5 situations of squat (knee 90°, 120°, 180°, right feet and left feet). The time of each training set was 30 seconds followed by a 20 seconds as rest time between each set. Results: Results: There was no significant differences in amplitude and frequency of electrical waves of rectus femoris, vastus lateralis, vastus medialis muscles between both groups in pre- and post-tests (p>0.05). The significant differences was found in amplitude and frequency of electrical waves of rectus femoris, vastus lateralis, vastus medialis muscles in experimental group in pre- and post-tests (p<0.05). Conclusion: WBV training may affect the electromyography indexes of knee extensor muscles in non-athletic girls.
