          Abstract

          El objetivo es identificar las acciones técnicas de las karatekas que consiguen puntuar en competición y explorar si el comportamiento técnico puede discriminar entre diferentes niveles competitivos. Se ha registrado el comportamiento técnico de 35 karatekas, modalidad de kumite femenino, en un total de 40 combates (18 de nivel regional/nacional y 22 de nivel internacional). Se ha utilizado un diseño observacional situado en el cuarto de cuadrante de carácter nomotético y de seguimiento multidimensional. El registro se ha realizado con el programa Lince y una herramienta de observación "ad hoc" formada por un sistema mixto de formatos de campo y un sistema de categorías denominado FCSCSHIAIKUMITE. Se ha utilizado la prueba de Chi-cuadrado (p< 0,05) y se ha realizado un análisis de coordenadas polares, escogiendo como conductas focales aquellas relativas a la puntuación y como conductas condicionadas todas aquellas relativas a los demás criterios. Los resultados muestran que solo el criterio puntuación discrimina entre ambos niveles de rendimiento, sumando 152 puntos en nivel internacional frente a 78 en nivel nacional (p= 0,002). El Yuko es la forma de obtener punto más frecuentada en ambos niveles (76,4% vs 86,8%), no obstante, el Ippon es eficiente y frecuentado a nivel internacional (21,7%), y solo representa un 4,4% en combates de nivel nacional. En conclusión, hay dos aspectos que podrían ser de especial atención, el perfeccionamiento de las acciones técnicas de punto más habituales y de las acciones defensivas a esas técnicas, así como la eficacia para obtener más puntuación al utilizarlas.

          Translated abstract

          The aim is to identify the technical actions of the karatekas that achieve to mark in competition and explore if the technical behaviour can discriminate between different competitive levels. It has registered the technical behaviour of 35 karatekas, modality of kumite feminine, in a total of 40 fights (18 of national regional/level and 22 of international level). It has used an observational design situated in the chamber of quadrant of nomothetical character and of multidimensional follow-up. The register has made with the program Lince and a tool of observation "Ad hoc" formed by a mixed system of formats of field and a system of categories designated FCSCSHIAIKUMITE. It has used the proof of Chi-square (p< 0,05) and it has made an analysis of polar coordinates, choosing like focal behaviours those relative to the punctuation and like behaviours conditioned all those relative to the other criteria. The results show that only the criterion punctuation discriminates between both levels of performance, adding 152 points in international level in front of 78 in national level (p= 0,002). The Yuko is the form to obtain point more frequented in both levels (76,4% vs 86,8%), nevertheless, the Ippon is efficient and frequented to international level (21,7%), and only represents 4,4% in fights of national level. In conclusion, there are two appearances that could be of special attention, the improvement of the technical actions of point more usual and of the defensive actions to these technicians, as well as the efficiency to obtain more punctuation when using them.

            Energetics of karate kumite.

            It is speculated that anaerobic metabolism is the predominant source of energy in karate kumite. However, no experimental proof is currently available. The metabolic cost and fractions of aerobic and anaerobic energy of karate kumite fighting were investigated. Ten male nationally or internationally ranked karateka [means (SD) age 26.9 (3.8) years, height 1.80 (0.08) m, mass 77.2 (12.8) kg] performed two to four fights scheduled and judged like a championship. Oxygen uptake was measured continuously with a portable spirometric device. Blood lactate was determined immediately before, and minute by minute after, each fight. Aerobic, anaerobic alactic and anaerobic lactic energy were calculated from oxygen uptake during the fight ( VO(2)), the fast component of the post-fight oxygen uptake ( VO(2PCr)) above resting values and changes in blood lactate concentration (Net-BLC), respectively. Altogether, 36 fights lasting 267 (61) s were analysed. The referee's decisions caused an activity-to-break ratio of approximately 2:1. VO(2), VO(2PCr), and Net-BLC per fight were 165.3 (52.4) ml(.)kg(-1), 32.2 (7.2) ml(.)kg(-1)and 4.2 (1.9) mmol(.)l(-1); the overall energy cost above rest was 334.3 (86.3) kJ per fight. Fractions of aerobic, anaerobic alactic, and lactic energy sources were 77.8 (5.8)%, 16.0 (4.6)%, and 6.2 (2.4)%, respectively. The results indicate a high metabolic rate in karate kumite. However, the acyclic activity profile implies that aerobic metabolism is the predominant source of energy and there is anaerobic supplementation, mainly by high-energy phosphates.
