Abstract: | Introduction: Karate is a martial art in which the technics are performed by kicks, punches (hand) and rotational movements. Ura MAWASHI GERI is a kind of kick which involves the core stability muscles of Lumbar – Pelvic areas, Quadriceps muscle (Lower extremity) and knee and lumbar – pelvic joints while being performed. The purpose of this research is to determine the muscle stimulation time pattern of Gluteus Medius (GM), External Oblique (EO) and Quadriceps muscles such as Vastus Medialis (VM), Vastus Lateralis (VL) at any phases of the implementation of the technique by the dominant leg. The muscular activities of VM, VL, EO and GM in 5 Iranian healthy elite Karatekas (in average age of (21/4) were recorded by the Electromyography device. The onset latency of the muscle activity and the Goniometric data (Knee Joint) were defined after processing the RMS of data and according to the Mean+4sd. After that, the average of the obtained records was used to determine the onset of each muscle separately at all phases of the implementation of the techniques. The results showed Glutesus Medius, at the phases of one, four, and five, and Vatus Medialis, at the phases of two and six, and the External Oblique at the third phase act earlier in comparison with other muscles. |
