          Abstract

          RESUMEN En el trabajo que se presenta, se plantea como propósito analizar el desempeño táctico del ne waza en judokas escolares de la Isla de la Juventud y determinar las causas que han generado el bajo desempeño en este campo durante los Juegos Escolares Nacionales. Para este fin, se seleccionó una muestra de 16 judokas de ambos sexos, de las categorías 13-14 y 15-16 años. Los métodos fundamentales empleados en la investigación fueron la revisión documental, la observación científica, la entrevista y la medición. Los resultados mostraron poca ejecución y baja efectividad en los ataques. El osae waza fue el factor fundamental para obtener la victoria y el kansetsu waza ocupó la segunda opción jerárquica de preferencia en estas edades. Se corroboró el poco tiempo usado en el trabajo en el suelo durante el combate y que la frecuencia y variabilidad técnica fueron aceptables, mientras que la actividad táctica ofensiva y defensiva no fue suficiente para mejorar los resultados.

Os métodos fundamentais utilizados na investigação foram a revisão documental, a observação científica, a entrevista e a medição. Os resultados mostraram má execução e baixa eficácia nos ataques. O osae waza foi o factor fundamental para obter a vitória e o kansetsu waza ocupou a segunda opção hierárquica de preferência nestas idades. Foi corroborado que pouco tempo foi gasto em trabalhos no solo durante o combate e que a frequência e variabilidade técnica eram aceitáveis, enquanto que a actividade táctica ofensiva e defensiva não foi suficiente para melhorar os resultados.

          ABSTRACT The work presented, has the purpose to analyze the tactical performance of the Ne Waza in school judo athletes from the Isla de la Juventud and determine the causes that have generated the low performance in this field during the National School Games. For this purpose, a sample of 16 judo athletes of both sexes, from the categories 13-14 and 15-16 years old, was selected. The fundamental methods used in the research were documentary review, scientific observation, interview and measurement. The results showed little execution and low effectiveness in the attacks. The osae waza was the fundamental factor to obtain the victory and the kansetsu waza occupied the second hierarchical option of preference in these ages. It was corroborated the little time spent working on the ground during the combat and that the frequency and technical variability were acceptable, while the offensive and defensive tactical activity was not enough to improve the results.

          A comparison of time-motion and technical-tactical variables between age groups of female judo matches.

          The aim of the study was to verify differences between age groups of female judo matches in time-motion and technical-tactical analysis. The sample was composed of pre-cadet (13-14 years, n = 148), cadet (15-16 years, n = 228), junior (17-19 years, n = 104) and senior (>20 years, n = 237) groups. The time-motion indicators consisted of total combat time, standing combat time, displacement without contact, gripping time, total time of techniques, groundwork combat time and pause time, per match and by each combat/pause cycle. Technical and tactical variables were also collected. The one-way analysis of variance and a post hoc test were conducted, P ≤ 0.05. Cadets, with a median of 7 (2, 12), had a number of combat/pause cycles different from junior, with 3 (1, 8.5). Regarding time-motion per match and per cycle, senior had longer total combat time, standing combat time and gripping time than other groups. Senior presented lower frequency of leg techniques than pre-cadet, cadet and junior. Time-motion and technical-tactical variables effects in female judo athletes emphasise the difference between seniors and other groups.

              Sex and Weight Category Differences in Time-Motion Analysis of Elite Judo Athletes: Implications for Assessment and Training.

              Sterkowicz-Przybycień, K, Miarka, B, and Fukuda, DH. Sex and weight category differences in time-motion analysis of elite judo athletes: implications for assessment and training. J Strength Cond Res 31(3): 817-825, 2017-The purpose of this investigation was to support training program development through the comparison of combat and pause phases during elite male and female judo competition in athletes of varying weight categories. A total of 1,411 video recorded judo matches between athletes who qualified for the 2012 Olympic Games were analyzed. Within the matches, 111,203 competitive situations were categorized as combat (with subphases of approach, gripping, attack, defense, and groundwork) or pause phases. Time-motion analysis data were compared between extra light, light, middle, and heavyweight categories for men and women. Median times varied between sex and weight category groups for individual combat (23.9-28.5 seconds), pause (4.0-8.8 seconds), and combat subphases (p ≤ 0.05). Sex-based differences in accumulated combat and combat subphase times were primarily found in the middleweight athletes. Heavyweight female athletes had longer accumulated groundwork and pause times, extra lightweight women had greater groundwork time, and both extra light and lightweight women had shorter accumulated attack times compared with their male counterparts. No differences between men and women were found for the time to complete an individual combat action; however, the pause phase and most of the combat subphases displayed differences. The lightest and heaviest judo athletes displayed unique characteristics compared with athletes in the other weight categories, particularly in the attack, defense, groundwork, and pause phases. These results have important implications related to training program design and support the need for the development of normative data for male and female judo athletes of varying weight categories.
