Mechanical Analysis of the Roundhouse Kick According to Height and Distance in Taekwondo
Competition regulation in taekwondo has experienced several changes during the last few years, for example, kicks to the head score more points than kicks to the chest. In addition, some external factors such as the height of target and execution distance seem to affect the kick performance. The aim of this study was to analyse selected biomechanical parameters (impact force, reaction time, and...
متن کاملEffect of Olympic Weight Category on Performance in the Roundhouse Kick to the Head in Taekwondo
In taekwondo, kick performance is generally measured using impact force and time. This study aimed to analyse performance in the roundhouse kick to the head according to execution distance between and within Olympic weight categories. The participants were 36 male athletes divided into three categories: featherweight (n = 10), welterweight (n = 15) and heavyweight (n = 11). Our results show tha...
متن کاملThe Impact of the Initial Stance Position on Lower Limb Joint Kinetics in the Taekwondo Roundhouse Kick
BACKGROUND: To achieve good performance, taekwondo athletes should optimize the stance position of the foot on the ground. OBJECTIVE: The aim of this study is to compare generated net joint power (hip, knee and ankle) during stance phase, magnitude of peak foot velocity of the attacking lower extremity and execution stance time produced from three stance positions (forward “0°”, diagonal “45°”,...
متن کاملRelative analysis of Taekwondo back kick skills’ biomechanics based on 3D photograph parsing
As photographing and video parsing techniques improved, it provides a boost for taekwondo technical researching. This paper make analysis of every stage features of back kick skills by using video parsing data, then based on analysis human gravity shifting features and relative features between hip angle and kick velocity in motion process, through analysis of each link of lower limbs’ velocity...
متن کاملEffect of Fatigue in Roundhouse Kick’s Reaction Time, Response Time and Impact Force in Taekwondo
The aim of the present study was to verify the effect of fatigue on reaction time, response time, and impact force during the roundhouse kick in Taekwondo athletes. Six competitive male athletes performed a time to exhaustion test. Results show that a specific protocol to exhaustion reduce impact force but do not change reaction time and response time during the roundhouse kick in Taekwondo ath...
