태권도 앞 꼬아서기 자세의 옆차기 숙련자와 비숙련자의 근 활성도 비교 분석

Abstract

Taekwondo Poomsae competitions use a deduct scoring method. The side kick corresponds to the 3rd level of difficulty and it is reported that the side kick makes people deducted frequently. The purpose of this study is to provide data to instructors and improve performance for Poomsae players by comparing and analyzing the muscle activity of the muscles on the side kick of the front cross stance position. Seven Taekwondo Poomsae elite practitioners and seven Taekwondo Poomsae non-skilled workers were selected and the side kicks in the front cross stance position were analyzed using EMG to compare muscle activity. The results of this study showed that 6 out of 8 muscles in the skilled group were superior to those in the unskilled group, and the important factors in the skilled group were the biceps femoris muscle, erector spinae muscle, and abdominal muscle. Non-skilled people performed side kicks inefficiently using only certain parts of the muscles, while skilled people performed side kicks in harmony and efficiency on muscles. Thus, it can be seen that unskilled people should perform side kicks using trunk muscles that bend the lower limbs muscles as much as possible toward the body to create a minimum angle for the knee joint and support them to hit(strike) the target point like skilled practitioner’s performance form.
