Abstract
ABSTRACT:: This study aimed to analyze the time-motion structure of combat phases (fighting: F; non-fighting: NF; and stoppage; ST) during semi-final and final matches (three 1.5-min rounds, with 1-min rest in between) of the 2010 Italian Taekwondo Cadet (age 13-14 years) Championship (males, n=40; females, n=28) in relation to gender (males and females) and grouped weight division (light, middle, and heavy) of athletes. Regardless of gender, grouped weight division, round, and tournament stage, differences (p<0.001, ES range: 1.92-3.02) emerged for frequency of occurrence of combat phases (F: 42.4 ± 0.5%; NF: 44.5 ± 0.7%; ST: 13.1 ± 0.9%) and their mean duration (F: 2.8 ± 1.0 s; NF: 6.5 ± 1.8 s; ST: 13.7 ± 5.0 s). A 1:2 F to NF ratio was found, whereas a 1:3 ratio emerged when F was considered in relation to the sum of NF and ST. During F, 5±1 tactical movements and 4±1 technical exchanges were performed, lasting 0.6±0.1s and 0.7±0.1s, respectively. These findings mirrored the intermittent nature of youth combat, characterized by a high occurrence of tactical movements and technical exchanges during F. The lack of differences for round and tournament stages indicates a limited tactical capability of young athletes in adopting specific match strategies, independently from gender and weight divisions of the athletes. To prepare young athletes to handle the technical-tactical demands of the match, coaches could include 7-9 circuit stations of specific TKD sequences of attack and counter attack techniques.

Artigo sobre o ko-uchi-gari


A technical-pedagogical and historical reflection on the
conceptual and biomechanical properties of Ko¯do¯kan
ju¯ do¯’s “ko-uchi-gari” [minor inner reaping throw]

Abstract
Throwing techniques represent an important part of Kōdōkan jūdō, aimed at defeating an opponent. Ko-uchi-gari [minor inner reaping throw] is a versatile throw of which the exact origin is unknown. Clear and correct jūdō-specific and didactic terminology are helpful in acquiring the complex motor skills that enable a refined and highly technical jūdō. Ko-uchi-gari relies on the physics principle of a “simple couple,” i.e., an acting pair of two bound opposing forces around the opponent’s center of mass with the result, in this case, being perpendicular to those forces, hence producing a torque. Appreciating this may provide an idea about the method this throwing technique is relying on to achieve its success and about its challenges. The purpose of the present paper is to improve the understanding of ko-uchi-gari from a historical, terminological, linguistic, technical, and biomechanical perspective in order to facilitate transferring or acquiring the motor skills necessary to properly master and teach this jūdō throwing technique.

Atenção à ausência de expressão dos atletas e ao fato de vários atletas em posição pior no ranking da FIJ terem sido selecionados.
