Background. The ranking system can be considered a measure of athletes’ performance. In addition, countries with high performance are expected to have better athletes. Problem and Aim. The present study aimed to verify whether ranking scores and country performance by competitors differ between winners and losers; and whether ranking scores and country performance by competitors could predict winners...
Background. The kumite section or karate kumite is characterized by high-intensity activity, including explosive actions. Problem and Aim. Determine the magnitude of the effect on the physical performance of karate athletes of the application of two protocols: HIIT-SPRINT and HIIT-JUMP performed at the beginning of a training session (20 minutes) for six weeks. Methods. Both the HIIT-JUMP and HIIT-SPRINT...
Background: Physiological measurements during simulated competitions are useful to make training programs more specific to sport-specific demands. Problem and Aim: The objective of the present study was to analyze the physiological response of kumite karate athletes during a simulated competition. Methods: Ten athletes from Chile’s national karate team (5 males, age: 24.2 ± 1.8 years, height: 1.67...
Introduction. Martial arts and combat sports are practiced by thousands of people around the world and increasingly discussed in scientific publications. Material and Methods. We describe an observational case study by describing and analyzing the activities of the II International Congress on High Performance Sports, an event hosted by Universidad Santo Tomas and the High Performance Center, Government...
Aim. The aim of this study was to determine differences in muscular activation and the moment of maximum electromyography amplitude pre- and post-impact of the roundhouse (bandalchagui) kick between novice and advanced taekwondo athletes. Method. Sixteen taekwondo competitors (four women) were categorized according to years of practice into novice (n = 8, < 3 years of experience) and advanced athletes...

We describe an observational case study by describing and analyzing the activities of the “Martial Arts and Combat Sports: Science, Research and Culture” event hosted by the University of Santiago, Chile. Results. Activities...
Background and Problem. Taekwondo is an Olympic sport characterized by the extensive use of kicking techniques which require a significant amount of explosive force and agility [Valdes-Badilla et al. 2014; Perez-Gutierrez et al. 2015]. It is considered an intermittent-high intensity short duration discipline, in which the predominance of the aerobic and anaerobic systems is alternated [Campos et al...
Aim and Method. The purpose of this study was to describe the physical performance (acceleration, number of impacts, distance and maximum speed) and physiological response (heart rate and blood lactate) of young female taekwondo athletes during combat simulations. Material. The sample consisted of seven girls (13.1 ± 1.1 years), who participated in a simulated taekwondo competition. Results. The main...
The purpose of the present study was to compare the physiological responses and the actions performed by taekwondo athletes from three different age groups. The sample consisted of children (10.9 ± 1.6 years), cadets (14.7 ± 1.3 years) and adults (23.4 ± 3.1) male taekwondo athletes, who participated in simulated taekwondo competition. Higher values were found in blood lactate cadets (9.49 ± 3.52...
