THE CHARACTERISTICS OF DOUBLE KICK IN THE AIR DURING ACTIVE AND PASSIVE ATTACK FOR ELITE TAE-KWON-DO ATHLETES

The purpose of this study is to discuss the reaction time and movement time of the double kick in the air (DKA) of the active and passive attacks for elite tea-kwon-do athletes. The experiment takes six male tae-kwon-do athletes (average age: 20.5 yearold; average height: 174.8cm; average weight: 63kg) who won the national match in the past 2 years as the subjects. A high speed camera (120Hz) was used to shoot their movements, which is quantified by a Silicon Coach at the same time. Based on the experimental result, the DKA can be a long, short, or rapid jumping attack movement, whose vertical displacement is large and the rolling angle of the body in the air is large. Therefore, it is suitable for the combo attack after the active attack in the competition
