Down sindromea duen kolektiboaren agilidadean, koordinazioan eta orekan taekwondo-a duen eragina

[EUS] Proiektu honen bitartez, Down sindromea pairatzen duten, >14 urteko 8 parte hartzaileen agilidadea, koordinazioa eta oreka ebaluatu izan da, taekwondo-ko ordu bateko lau saio eginez. Aipaturiko faktoreak neurtzeko, ECOMI eskala egokitua erabili da. Hau, lehenengo eta azkenengo saioetan erabili izan da, datuak hartzeko eta konparaketak egin ahal izateko, eboluzioa ikusiz. Neurketak behin eginda, ikusi egin da bai koordinazioan eta orekan hobekuntzak izan dituztela orokorrean, aldiz, agilitatean ez da hobekuntza aipagarririk egon, eta aldi berean, parte hartzaileen arteko aldea nahiko nabarmena izan da. Hobekuntza ezak edo txikiak izateak, denbora eskasagatik izan dela esan daiteke. Beste autore batzuen esanetan, 20 saiotan hobekuntza nabarmenak lortu daitezke.

Incidência e Caracterização de Lesões Desportivas no Taekwondo segundo o Gênero

Taekwondo practice has been associated with physical and biomechanical overloads, which are related to occurrence of sports injuries (SI). However, etiological and nosographic information about SI are limited and conflicting. This study analyzed and characterized the SI in Taekwondo athletes, according to gender. Casuistic integrated 22 athletes, 12 men and 10 women, athletes from São Paulo State Team of Taekwondo, adult category, with 23,6±6,8 years, body weight of 66,0±13,1 kg and 1,72±0,09 m of height. Reported morbidity survey was used to obtain retroactive information to 2009 season. Nosographic variables were analyzed using Goodman’s Test for contrasts among multinomial populations. All athletes reported injuries in the season; 56 cases were registered, determining an injury rate of 2.54 SI/athlete; 26 events (46.4%) occurred in males (2.17 SI/athlete), and 30 (53.6%) were related to women (3.00 SI/athlete). There were predominance of injuries in joints (35,7%) and muscles (39,3%); both genders presented injuries in lower members (82.1%, p<0.01), predominant in combat situations (80.4%, p<0.05), during the preparatory period of training (73.2%). There was a higher treatment request among male athletes (73.1%), which showed high asymptomatic return (69.2%); the female group referred similar proportions of absence and presence of treatment request, collaborating for the greater symptomatic return of these athletes (70.0%). In conclusion, the results support predominance of muscles and joints injuries in lower segments, derived from fighting, involving female athletes.

Talent detection in taekwondo: which factors are associated with the longitudinal competitive success?

Background Several morphological and functional characteristics are associated with the performance of taekwondo (TKD) adult athletes. However, we did not find any longitudinal study associating these features to the future performance of young athletes, and thereby, identifying the best variables to use in a battery of tests to talent detection. Therefore, the aim of this study is answer the question which factors are associated with the longitudinal competitive success of TKD young athletes over five competitive years (2008 to 2012).Material &Methods: Six taekwondo athletes (13.06 +/- 1.07 years, 43.6 +/- 6.6 kg, 157.9 +/- 8.3 cm), who trained three to six hours per week, for more than three years, were assessed on 32 maturational indicators, of body composition, anthropometric and functional, using anthropometric techniques, dual energy x-ray absorptiometry, carpal radiography and contact platform. To determine the competitive ranking, the competitive results of athletes from 2008 to 2012 were analysed, and these values were correlated with the other 32 indicators for determining the Longitudinal Predictors of Performance in TKD (LPPT). Moreover, one of the athletes achieved results notably higher than the other, being medalled at Junior World Championships. Therefore, all variables were transformed into z-scores and all those in which this athlete presented superior performance in 1 z-scores were considered as LPPT. Results: The athlete of reference (the first in Longitudinal Competitive Ranking 2008-2012) distinguished, in accordance with the criteria, in nineteen LPPT indicators. The ranking was correlated with 6 LPPT parameters, including one from the maturation group of indicators and five from the functional group.Conclusion: Our results allowed us to identify several factors that are related to longitudinal competitive success in taekwondo young athletes. These factors should be considered by coaches to the proper selection of training programs, as well as for the pre-selection of young talents in competitive taekwondo. However, these results apply only to the Portuguese taekwondo adolescent athletes, being of limited generalizability.

Energy demands in taekwondo athletes during combat simulation

The purpose of this study was to investigate energy system contributions and energy costs in combat situations. The sample consisted of 10 male taekwondo athletes (age: 21 +/- 6 years old; height: 176.2 +/- 5.3 cm; body mass: 67.2 +/- 8.9 kg) who compete at the national or international level. To estimate the energy contributions, and total energy cost of the fights, athletes performed a simulated competition consisting of three 2 min rounds with a 1 min recovery between each round. The combats were filmed to quantify the actual time spent fighting in each round. The contribution of the aerobic (WAER), anaerobic alactic (W-PCR), and anaerobic lactic (Wleft perpendicularLA-right perpendicular) energy systems was estimated through the measurement of oxygen consumption during the activity, the fast component of excess post-exercise oxygen consumption, and the change in blood lactate concentration in each round, respectively. The mean ratio of high intensity actions to moments of low intensity (steps and pauses) was similar to 1:7. The W-AER, W-PCR and (Wleft perpendicularLA-right perpendicular) system contributions were estimated as 120 +/- 22 kJ (66 +/- 6%), 54 +/- 21 kJ (30 +/- 6%), 8.5 kJ (4 +/- 2%), respectively. Thus, training sessions should be directed mainly to the improvement of the anaerobic alactic system (responsible by the highintensity actions), and of the aerobic system (responsible by the recovery process between high- intensity actions).

Las artes marciales son un modo de vida. Disciplina corporal, moralidad y trabajo entre los practicantes de Taekwondo y Gumdo en Geoje-Do, Corea del Sur. En: LaRivada, V. 3, nº 4

La tesis de Gonzalo Ariel Millán titulada “Las artes marciales son un modo de vida”. Disciplina corporal, moralidad y trabajo entre los practicantes de Taekwondo y Gumdo en Geoje-Do, Corea del Sur” busca dar cuenta de la producción de un tipo particular de cuerpo y experiencia sensorial como es la de los practicantes de dichas artes marciales. Aplicando la técnica de observación participante, Millán se somete al proceso de socialización propio de estas disciplinas marciales captando sus particularidades así como aquellos elementos que las artes marciales coreanas tienen en común con la estructura social y la historia del pueblo coreano.
