The relationship of a number of biokinematic variables and dynamic balance to the accuracy and strength of the crescent kick performance of advanced taekwondo players

الملخص

The research aimed to identify the relationship between a number of biokinematic variables and dynamic balance and the accuracy and strength of the crescent kick to the head performance for advanced Taekwondo players. The researchers assumed the existence of a significant correlation between a number of biokinematic variables and dynamic balance with the accuracy and strength of the crescent kick to the head performance for Taekwondo players. The researchers used the descriptive approach to suit the nature and objectives of the research. The research sample included (7) advanced Taekwondo players in Nineveh Governorate. The researchers used the crescent kick to the head test to measure the accuracy and strength of the crescent kick, in addition to using the dynamic balance test (YBT) for the legs. The scientific and technical observation was carried out using digital cameras to photograph the crescent kick to the head test. The data were statistically processed using the (Spss) program. The researchers concluded that the variables (horizontal displacement of BMC, time, horizontal velocity of BMC, angular velocity of the kicking leg, radius of the kicking leg, resultant velocity of BMC) in the main phase of the crescent kick to the head have an effective role in achieving the accuracy and strength required for performance, in addition to the direct effect of dynamic balance in providing a good balance base for performing the crescent kick to the head for Taekwondo players.
