Abstract

The purpose of the research was to compare muscle torque of elite combat groups. Twelve taekwondo WTF athletes, twelvetaekwondo ITF athletes and nine boxers participated in the study. Measurements of muscle torques were done under static conditions on a special stand which belonged to the Department of Biomechanics. The sum of muscle torque of lower right and left extremities of relative values was significantly higher for taekwondo WTF athletes than for boxers (16%, p < 0.001 for right and 10%, p < 0.05 for left extremities) and taekwondo ITF (10%, p < 0.05 for right and 8% for left extremities). TaekwondoITF athletes attained significantly higher absolute muscle torque values than boxers for elbow flexors (20%, p < 0.05 for right and 11% for left extremities) and extensors (14% for right and 18%, p < 0.05 for left extremities) and shoulder flexors (10% for right and 12%, p < 0.05 for left extremities) and extensors (11% for right and 1% for left extremities). Taekwondo WTF andtaekwondo ITF athletes obtained significantly different relative values of muscle torque of the hip flexors (16%, p < 0.05) and extensors (11%, p < 0.05) of the right extremities.

Abstract

Hill and Barton (2005) showed that fighters in tae kwon do, boxing, and wrestling who wore red jerseys during the 2004 Olympic Games won more often than those wearing blue jerseys. Regarding these results, this study investigated the effects of jersey color during a combat situation on fighters' physical parameters of strength and heart rate. An artificial, experimental combat situation was created in which the color of sport attire was assigned randomly. Fourteen pairs of male athletes matched for weight, height, and age had to fight each other: once in a red jersey and once in a blue. Heart rate (before, during, and after the fight) and strength (before the fight) were tested wearing the blue and the red jerseys. Participants wearing red jerseys had significantly higher heart rates and significantly higher pre-contest values on the strength test. Results showed that participants' body functions are influenced by wearing red equipment.

Aspectos psicológicos de atletas de TKD


Summary
Introduction. The aim of the present investigations was to evaluate selected motor and psychological factors characterising students training Olympic taekwondo at various level of sports advancement. Material and methods. Forty students of the Universities from Zamość representing Olympic taekwondo took part in the
research. The type and structure of personality were measure by Questionnaire of Personality of ZKKO Zuckerman-Kuhlman and International Committee on the Standardisation of Physical Fitness Tests (ICSPFT) were measure level of physical fitness. Results. The research proved that personality features under investigation, i.e. Imp-SS, N-Anx., Agg-Host, Act. fall into the range of medium results. The group of subjects demonstrating high levels of sports advancement Imp-SS and N-Anx fall into the range of low results. The other features, i.e. Agg-Host, Act. and Soc. are at the level of medium results. As far as the group of subjects with medium levels is concerned, all personality traits fall into the range of medium results.
Conclusion. It was observed that competitors with higher levels of physical fitness manifest higher levels

Até que enfim um protesto contra as regras novas do judô

Um pouco radical, mas acredito ser importante que alguém se manifeste...
