The Symmetry In Kinematics Between The Dominant And Non-Dominant Legs In Taekwondo Turning Kick Hafizah Harun & Siau Jun Xiong Fakulti Pendidikan, Universiti Teknologi Malaysia Abstract : The objective of this study was to determine the differences between dominant and non- dominant leg in Taekwondo Turning Kick. There were 5 subjects who are Johor state national level black belt Taekwondo players with the mean age 21.71 ± 2.58 years old, mean weight 55.87 ± 6.76 kg and mean height 170.22 ± 5.41 cm. This research was carried out in the XF Dance and Martial Arts Studio, located in Bandar Putra, Kulai, Johor. A Sony DCR-HC38 digital video camera with 25 frames per second (fps) was used for the sagittal view recording. Movements analysis software - SiliconCoach 7 were used in the digitizing process, which were done manually with a reference point marked at the tarsal bone. The results were focused, firstly, on the comparison of the dominant and non-dominant kicking speeds and secondly, the relationship between the vertical kicking angle and the maximum height at the target spot. The results showed that mean peak velocity for the dominant and non-dominant kick were 12.93 m/s and 12.27 m/s respectively. T-test showed that there were no significant differences in velocity between dominant and non-dominant legs in Taekwondo turning kick. Therefore the null hypothesis of this research was achieved. The mean dominant vertical angle was lower than the mean non-dominant angle which were 70.62° and 72.68° respectively, whereas the mean height of the kick by dominant leg was higher than mean height of the kick by non- dominant leg (1.23m and 1.20m respectively). In conclusion, the expert Taekwondo players were equally fast and efficient during the turning kick when using both dominant and non-dominant legs.

It is also a form of physical exercise to develop ones strength and agility as well as to maintain both physical and mental health. Taekwondo is distinct from Chinese Kung Fu and Japanese Karate. “Tae” (Hangul: 태, hanja: 跆) means to kick, attack or defend with the feet. “Kwon” (Hangul: 권, hanja: 拳) means to punch, strike, or smash with the hand or fist to defend and attack. “Do” (Hangul: 도, hanja: 道) means the art and the way, the methodology of application of our human body parts. Taekwondo is known as one of the combat-oriented sport. This sport uses only hands and feet without any weapons. Due to the unique variety of kicking techniques practiced in Taekwondo, many people have come to call it the “Kicking Martial Arts” although it also practices a fair amount of hand and fist techniques. Taekwondo is famed for its use of kicking techniques, which distinguishes it from others martial arts. Under the latest World Taekwondo Federation (WTF) rules and regulations, sparring takes place between two competitors in an area measuring 10 meters square. Each match or bout consists of three non-stop rounds of contact. Breaks are given between rounds. Points are awarded for permitted, accurate and powerful techniques to the legal scoring areas. Light contact or insufficient impact of kicking to the scoring area does not merit any points. Unlike soccer which determines its’ winners easily by the total number of goals, Taekwondo is “a very subjective sport” when it comes to scoring. “Even if you have one of the best fights of your life, you can still lose based on the scoring.”(Cogan, 2008).
