Abstract

Karate-Do is an Olympic combat sport with origin in Okinawa island, practiced by people from all over the world with different styles and that have technical characteristics that differ from each other. In Karate-Do fights, performances must strike their opponents with foot and hands that demonstrate control and technique, called sun dome. The impact of a foot or hand strike with excessive force or injury, is considered an infraction and may be a disqualifying factor in a competition. The objective of this study is to compare the sun dome technique, according to different ranks among the Karatekas of the Shorin Ryu school in the city of João Pessoa, taking into anthropometric indicators. The research was of the descriptive type with the quantitative approach. The sample consisted of 30 students from a Karate school, being 21 male and nine female, respectively 13 graduates and 17 were classified as beginners. The variables investigated were body mass, height, wingspan, graduation, training time and sun dome distance, measured by means of an ultrasonic distance sensor coupled to a programmable microcontroller and a notebook computer. The results obtained are those that have graduates with more control of the sun dome technique than the beginner Karatekas, while the others variables are undifferentiated.
