Khanzadeh, S., Sadeghi, H., Choghagalani, S. K., & Hoseiynpour, S. (2015). Muscle stimulation timing while implementing Ura Mawashi Geri in Iranian elite women. J. Hum. Sport Exerc., 9(Proc2), pp.S677-S686. 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.

Biomechanical Analysis of Mawashi-Geri in Technique in Karate: Review Article

“…In addition, it is also consisted of skills and physical arts that is an active and dynamic (3) that involves multiple muscles. The activity of these muscles is associated with flexion, extension and rotation of various joints (4,5). Foot techniques in Karate include Mae-Geri, Mawashi-Geri, Ora Mawashi-Geriand Yoko-Geri.…”

Incidencia de la contextualización en la adquisición de los elementos técnicos - tácticos del Karate Do durante la iniciación deportiva (Incidence of contextualization in the acquisition of tactical technical elements of Karate Do for the Sport Initiation

“…A partir de lo anterior, se busca darle un vuelco metodológico a la enseñanza del Kárate Do, aplicando alternativas que favorezcan la adquisición de los elementos técnicos -tácticos de esta disciplina durante la fase de iniciación deportiva, asumiendo la incorporación de procesos de desarrollo del pensamiento más relacionados con la producción, aplicación y creación (Montes, Leff, Gallopin, Gutman, Vessuri, Fernández, Marulanda, Morello, Robirosa & García, 2000), así como métodos más problémicos como la modelación y simulación (Corona, Fonseca, Figueiras & Hernández, 2002;Suwarganda, 2015;Khanzadeh, Sadeghi, Choghagalani & Hoseiynpour, 2015;Ramasamy & Suwarganda, 2015), de tal manera que se potencie el desarrollo de habilidades tácticas durante la iniciación (lo anterior se profundiza en el apartado metodológico del presente artículo).…”
