In Karate, there are series of punching and kicking techniques that fighters use for scoring. Objectives. The aim of this research was to determine the most scoring techniques and their frequencies in final kumite competitions of 2016 world karate championships. Methods. By ...

In this paper, we propose an innovative automatic evaluation process for any sport motions. Based on a 2-level Dynamic Time Warping, the process allows the evaluation of both spatial and temporal errors of a novice motion based on an experts’ motion database and without any prior knowledge on the sport. This new methodology is evaluated with regards to coaches’ assessment on two different kinds...

Abstract. Simplicial complexes represent useful and accurate models of complex networks and complex systems in general. We explore the properties of spectra of combinatorial Laplacian operator of simplicial complexes and show its relationship with connectivity properties of the Q-vector and with connectivities of cliques in the simplicial clique complex. We demonstrate the need for higher order...

introduction: stereotypy is one of the main features of children with autism. these behaviors are associated with deficit in learning processes, social skills acquisition, increased family stress, and self-injuries behaviors. the purpose of the present study was aimed to investigate the effectiveness of two selected karate-hand techniques on hand stereotypic movements in a boy with autism. mate...

Karate is a widely practiced combat sport. Karatekas’ body composition has typically been obtained in small groups using skinfolds or bioelectric impedance. In this work, we assessed three-compartment the accurate dual-energy X-ray absorptiometry technique (QDR Horizon, Hologic) large sample (n = 58; 74% males) of black belt karatekas. Stature-adjusted indices (fat mass index; fat-free bone min...

We propose a method of community detection that is computationally inexpensive and possesses physical significance to a member of a social network. This method is unlike many divisive and agglomerative techniques and is local in the sense that a community can be detected within a network without requiring knowledge of the entire network. A global application of this method is also introduced. S...

Background. Studies in this domain help focus on the techniques with high application to improve the point attainment, without providing points for the other opponents. Objectives. The purpose of this study was to analyze and investigate the most common scoring techniques used and the highest intensity competition times that have been fulfilled by the champions of the World Karate Leagues 2019...
