... This conference also illuminated some problems with Taekwondo literature. With the exceptions of some biomechanics studies (e.g., Heller et al., 1998;Wąsik, 2007Wąsik, , 2009Wąsik, , 2011 and historical articles (e.g., Heo, 2015;Johnson & Vitale, 2018), ITF literature is greatly overshadowed by research on its Olympic counterpart. It is therefore understandable that the two main presenters would not be well-versed in ITF literature. ...
p>General Choi Hong Hi has long been a controversial figure in the Republic of Korea (ROK; South Korea) despite his extreme influence on Taekwondo. The “Conference for the 100<sup>th</sup> Anniversary of Choi Hong Hi: Taekwon-Do and Life; How to View Choi Hong Hi” was held on November 28, 2018 at the Korea National Sport University. This report on that conference intends to disseminate the speakers’ findings to a wider audience and establish new directions for academic discussions on International Taekwon-Do Federation (ITF) Taekwon-Do. This conference also illuminated some problems with Taekwondo literature; namely that ITF literature is greatly overshadowed by research on its Olympic counterpart. Additionally, it seems that the only ROK Taekwondo governing body interested in reestablishing General Choi’s legacy is the Taekwondo Promotion Foundation. Nevertheless, even though he was a taboo topic in the ROK a decade ago, the political climate in the ROK has changed and General Choi’s legacy is re-emerging slowly.</p
... Second research conducted by Bedolla [16] and Ke-Tien [17] anaerobic endurance along with the explosive force are determining factors for success during the fight. However for Lin et al. [18], Sadowski et al. [19] and Wąsik [20,21] beyond these physical factors mentioned above, the technical and tactical factors also are critical to good performance during the fight, and therefore should not be overlooked by coaches. ...
Background & Study Aim: Taekwondo WTF, together with wrestling, judo, and boxing, is a combat sports that is part of the Olympic Games
... Having adopted commonly used biomechanical analysis criteria of sports technique [15] as well as quantification means used in taekwon-do research in particular [16,17], the axe kick was broken into four stages, i.e. the initial stance (preparatory phase), foot take-off, the upswing, and the downswing. The four stages were kinematically captured and analysed using six high-speed cameras. ...
Background & Study Aim: Taekwon-do is famous for its powerful kicking techniques and the axe kick is the challenging one, aiming at kicking high section of an opponent. The relevance of the skill in the traditional version of taekwon-do is that a single strike might happen to reveal the winner. The main aims of the study were 1) the kinematic characteristics of the axe kick using motion capture technology and 2) the kinematics conditions leading to maximization of kick effectiveness. Material & Methods: Six International Taekwon-do Federation (ITF) practitioners participated in the study and each of them performed the axe kick (neryo chagi) three times. Using a 3D motion capture technology, selected parameters such as maximum kick foot velocity, durations of take-off, the upswing, the downswing as well as the whole kick and the kick leg angle at maximum velocity were quantitatively determined. The basic descriptive statistics (means & standard deviations) and correlation analyses were performed for revealing the dominant factors related to the kick. Results: The results indicate that the maximum kick power appears around 45° of the kick leg to vertical direction or 85-89% of one's body height (i.e. the optimal offence/attack height) during the downswing. The variation of the optimal offense height depends on one's body height, gender and race. And the keys for increasing the kick effectiveness are balanced weight transfer, large hip ROM for pre-lengthening hip extensors and follows an explosive foot downswing for maximizing kick-foot power. Conclusions: The above observations: the maximal kick power occurs around 45° of the kick-leg to the vertical direction during the downswing; shortening the downswing phase could increase the axe kick quality further.
