A Study on Impact Analysis of Side Kick in Taekwondo

Abstract

Taekwondo is a martial art form and sport that uses the hands and feet for attack and defense. Taekwondo basic motion is composed of the breaking, competition and poomsea motions. The side kick is one of the most important breaking motions. The side kick with the front foot can be made in two steps. In the first step, the front foot is extended forward from the back stance free-fighting position. For the second step, the rear foot is followed simultaneously. Then, the side kick is executed while the entire body weight rests on the rear foot. In this paper, the impact analysis on a human model for kicking posture was carried out. The ADAMS/LifeMOD used numerical modeling and simulation for the side kick. The numerical human models for assailant and opponent in competition motion were developed. The maximum impact force on the human body was obtained by experiment and was applied to impact simulation. As a result, the impact displacement and velocity of the numerical human model were investigated.

Sport-specific balance ability in Taekwondo practitioners

“…Rotation of the body and pivoting on one leg is an essential component in all of these kicking skills. Previous studies found that elite TKD athletes could turn and kick at high speeds (5.2m/s to 16.26m/s) and they generate huge amount of striking forces (390.7N to 661.9N) without loosing balance (Pieter and Pieter, 1995; Lee et al, 2008). In addition to turning and kicking, TKD practitioners adjust their body position and distance to the opponent frequently by stepping to different directions during competitions in order to score points.…”

Impact Force and Velocities for Kicking Strikes in Combat Sports: A Literature Review

“…The velocity of kicks was reported in 31 instances for the roundhouse kick [ 2 , 12 , 21 , 26 , 28 , 29 , 31 , 32 , 42 , 43 , 44 , 46 , 47 , 53 , 57 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ], 10 for the roundhouse kick to the head [ 24 , 59 , 66 , 67 , 75 , 76 , 77 , 78 , 79 , 80 ], 8 for the side kick [ 13 , 25 , 28 , 57 , 65 , 71 , 72 , 81 , 82 ], 19 for the front kick [ 11 , 45 , 55 , 57 , …”

“… Means and standard deviations of peak linear foot velocity (m/s) for kicking strikes in combat sports: ( a ) roundhouse kick, ( b ) roundhouse kick to the head; ( c ) side kick, ( d ) front kick, ( e ) back kick, ( f ) axe kick. Where an error bar is absent, only a maximum velocity value was reported [ 2 , 11 , 12 , 13 , 21 , 23 , 24 , 25 , 26 , 28 , 29 , 31 , 32 , 42 , 43 , 45 , 46 , 47 , 50 , 52 , 55 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , …”

“…Where an error bar is absent, only a maximum impact force value was reported. Where only N/KG was reported, an average participant weight of 75 kg [ 121 ] was used to calculate impact force [ 11 , 13 , 22 , 24 , 27 , 30 , 44 , 48 , 49 , 51 , 52 , 54 , 55 , 56 , 66 , 67 , 72 , 81 , 82 , 84 , 88 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 ].…”

“…Thoroughly understanding how a human responds in an impulsive environment is essential to prevent injuries [2,3]. Many improvements have been accomplished through various studies and analyses, and these results have been applied to new aircraft designs [4].…”
