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.
