“The aim of this study was to compare the fighting strategies between medalists and non-medalists in Taekwondo. A total of 107 matches from the 16th Asian Games had been video-taped for notational analysis. Round house kick was the most frequently used kick by the medalists in the competition (63.29%) while cut down kick (9.26%) and push kick (7.08%) were ranked second and third respectively. Aggressive mode of attack was the dominant fighting strategy used by the medalists (63.17%). Discrepancies in fighting strategies between Taekwondo medalists and non-medalists were found in this study including mode of attack, use of turning attack, and number of types of kick employed.”

The purpose of the present study was to examine the validity of using a 20 meter multistage shuttle run test to estimate maximal oxygen uptake.

Twenty-two elite taekwondo athletes (11 male, 11 female, members of the Turkish young national team), participated in the study. The respiratory gas exchange parameters were measured using portable gas analysis system while shuttle run test was carried out. All tests were performed last August 2004, in the gymnasium of Suleyman Demirel University, Isparta, Turkey.

Analysis of the test scores showed a mean score on gas analysis of 51.79 ml/kg/min and a mean score of 43.59 ml/kg/min on the shuttle run test. On average, the scores predicted by the shuttle run test were 16% lower than those for the gas analysis score. The correlation between the tests was significant at a level of r = 0.810.

Maximal oxygen consumption (VO2 max) can be predicted from shuttle run test scores, but not as indicated with the test package. In order to obtain the true score one must apply a regression equation.”

Objective: To report rates of injuries sustained during Junior taekwondo competitions.

Design: Prospective.

Materials and Methods: Data were collected with simple check-off forms that describe the athlete, nature, site, circumstances, and severity of the injury at three major taekwondo tournaments involving a total of 3,341 boys and 917 girls.

Main Results: No difference was found between boys (58.34/1,000 athlete-exposures) and girls (56.57/1,000 athlete-exposures) in total injury rate (p > 0.05). Collapsed over gender, significant differences (p = 0.013) in injury rates of body parts were found with the lower extremities (21.83/1,000 athlete-exposures) ranked first. Unblocked attacks are the major cause of injury in both boys and girls.

Conclusions: Coaches are advised to work on the blocking skills of their Junior taekwondo athletes. No head contact for children in taekwondo competition should also be considered.”

Relationship between attack and skipping in Taekwondo contests

“The purpose of this study was to determine the relationship between attack time (AT) and skipping time (ST) during the 2007 Taekwondo World Championship and 2008 Beijing Olympic Games. A total of 22 matches (65 rounds, 13 semifinals, and 8 finals) from the World Championship and 23 matches (63 rounds, 22 rounds with 16 athletes each and 1 quarterfinal round) from the Olympic Games, both in the male category, were assessed using time-motion analysis. The AT was considered as the total time during which the athlete attacked or tried to attack, whereas ST was the total time without attempting to attack. The ratio of AT to ST was ∼ 1:7 based on the data pooled from the 2 competitions. The AT/ST ratio was significantly lower for the World Championship than for the Olympic Games (p ≤ 0.05). In the Olympic Games, no consistent differences across weight divisions were found. However, during the World Championship, the heavier weight divisions (>78 kg) exhibited a lower average AT, lower summed AT, lower attack numbers (ANs)and higher average ST than lighter weight divisions (<58 kg, p ≤ 0.05). For both competitions, the ST was lower, and the ANs and AT/ST ratio were higher in round 3 than in round 1 or 2. In conclusion, the results of this study suggest that matches in the Olympic Games were less cadenced than in the World Championship, but that in both competitions, the intensity of the match increased in round 3. Practically, these data suggest that coaches need to structure Taekwondo training sessions in a manner that allows the work/pause ratio to mirror the physical demand imposed during competitions.”

The aim of the study was to identify selected success factors of elite Olympic taekwondo competitors in the context of medals that they have or have not won during Polish Junior Championships (PJCs).

Material and methods.
Sixty-three elite male taekwondo competitors took part in the study. The competitors were divided into two groups on the basis of their achievements: PJC medallists and non-medallists. Factors determining sports success were modelled with the use of a general linear model (GLM). The procedure lasted until the minimum of the quality criterion, i.e., the Akaike information criterion (AIC), was reached.

Successful competitors (medallists) demonstrated significantly better conditioning, technique, coordination and structural parameters. Dynamic strength, general endurance, technical skills (e.g., roundhouse kicks), complex reactions and low adiposity levels were the factors that contributed to the achievement of excellent results in taekwondo.

The research results revealed groups of success factors in taekwondo at a national level. Variables concern- ing coordination factors (complex reaction – 16%) and technical factors (360° dollyo chagi montong – 8.8%) exerted the great- est influence on point scores.”
