Kinetics of the financial kicks - European Champion measurement taekwon-do
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2014, Vol 24, Issue 68
Abstract
Purpose of the study.The purpose of the study was trying to kinetic identify factors of rotation kick based on values of speed of the feet, the pressure forces on the ground and kicks time.Materials and methods.17 years old athlete weighing 75 kg, 179 cm growth, the holder of the degree and Dan, winner of the title of European Champion in taekwon-do ITF was analyzed. For research it was used a system for comprehensive traffic analysis BTS Spa Italian company called Smart-D.Results.Indicators describing the structure of space-time motion of markers placed on the foot and on the wrists of both hands were registered. In this way, the speed variations as a function of time was specified. Average values of the parameters that were obtained were used to determine the speed of the curve changes as a function of the relative length (performing kick) leg of the athlete. In this way, the average maximum speed of the feet and hands relative to the X, Y and Z axises was determined, also the time of the kick and the maximum force on the ground and the foot supporting force of the foot kicking at its reflection.Conclusions. It was noted that the speed of the foot kicking correlates with sweeping movement of the hands (r = 0.64 for the right hand and r = 61 for the left hand). This may be due to that kinetics of the kicks rotation depends on the correct and dynamic arm swing. The resulting measurements of force on the ground supporting feet shows three characteristic peaks. The first appears right after reflection rate. These values are strongly correlated to the speed of kicking foot (r = 91). The second appears at the time of obtaining the maximum speed of the other foot, and a third informing about returning to the starting posture.
