Analysis of Injury Factors according to Foot Angle of Jumping Front Kick in Taekwondo

The purpose of this study is to analyze the factors of injury according to the landing foot angle of the jumping front kick and to present the ideal landing method and the landing foot angle. The impact variables were analyzed by selecting 13 participants (age: 20.8±0.8 years, height: 171.4±4.1 cm, body weight: 66.1±6.1 kg, career: 7.6±4.6 years) who could adjust the angle of foot at the landing phase during the jumping front kick. As a result, the mean impact force durng landing phase was greater 45° and 90° than 180°. The maximum vertical ground reaction force was greater 90° than 135° and 180°. The loading rate and vertical stiffness were greater 45° and 90° than 135° and 180°. Base on the results, it is believed that landing of the footwork by turning at least 135° after a forward kick will relieve the shock and load transmitted to the human body a little bit.
