- W1413603115 abstract "Background & Study Aim: An important aspect of ap bal ap dolio tchagui kick in tae kwon do is that it is usually performed in reaction to a signal or event. That is, given a specific stimulus (i.e. the movement of the opponent), the tae kwon do athlete must react as quickly and accurately as possible to the stimulus. Reacting to a stimulus requires preparation and it is essential to determine this preparation of an elite athlete to perform a task. Therefore, to investigate this movement a reaction time paradigm is appropriate wherein the athlete accomplishes the kick in response to a stimulus. The study investigates the processing, reaction and motor response of male and female athletes in an ecological task. The purpose of this study was to verify the authenticity of the two hypotheses: (1) that the pre-motor time, response time and motor time would be the same for males and females; (2) that the magnitudes of the muscle activation would be different between males and females. Materials & Method: The main method is an analysis and comparative study of empirical data. We collected data on 13 Brazilian national calibre tae kwon do athletes (6 male and 7 female) when performing a simple reaction time kicking manoeuvre. The experimental equipment included EMG electrodes placed on six muscles and an electrogoniometer placed on the knee of the kicking limb. Results: We found that pre-motor and response times were faster for females than males for several muscles but the faster movement time for males was sufficient to equate the total time between males and females. These results suggest that quantification of biomechanical parameters from skilled athletes allows coaches to understand the movement which will ultimately improve the technique to establish training goals. Conclusions: It is suggested that the knee extensors muscles are mainly responsible for a kicking movement. Our data showed that trunk stabilizers were activated prior to the main knee extensors muscles. In tae kwon do, athletes have to be very precise and fast in order to surprise their opponent, avoiding defence and counterattack. Monitoring pre-motor muscle activation during training sessions, potentially gives support for specific training and/or aiming movement optimization." @default.
