Background and Study Aim: The traditional karate is a martial art that includes an application of many forms of kick in situations to combat sports, this way, involving different training methods to improve the technique of kicking. The objective of this study was analyse the kinematics variables of the front kick of karate practitioners of traditional style in conditions with impact in a target and without impact.
Material and Methods: For the study, were collected the anthropometrical data from 8 graduate male karatekas with brown and black belt (time of medium training 13.7 +; 4.7 years). The assessment of kinematic of the kick was made by means of computed kinemetry, acquiring 3 sequences of front kick in conditions with and without impact with both sides of the individuals, being analyzed in the software Skillspector 1.3.2. The statistical analysis was performed in the software SPSS version 15.0.
Results: The results of the study demonstrated that the subjects were with mean of age of 30.1 +; 10.2 years, body weight of 85.3 +; 16.2 kg and height of 178.9 +; 4.9 cm. In relation to the kinematics variables analyzed the velocity of 5th metatarsus in the condition with impact and using the dominant member was significantly larger than the other conditions, as well as at the speed of the lateral malleolus in the condition with impact and utilizing the dominant member. In relation to the angle of the ankle joint the condition without impact presented better results, the knee joint the best results were seen in the condition without impact.
Conclusions: Finally, the study concludes that the kicks conducted with impact by the dominant member has higher speed values, however the kicks without impact present better angular conditions to the technique of the kick. Therewith, recommends that it be prioritized in sports training traditional karate the application of kicks with the impact targets.
