Relationships between recall of perceived exertion and blood lactate concentration in a judo competition
2001
Relationships between perceived exertion and blood lactate have usually been studied in laboratory or training contexts but not in competition, the most important setting in which sports performance is evaluated. The purpose of this study was to examine the relationships between psychological and physiological indices of the physical effort in a competition setting, taking into account the duration of effort. For this, we employed two Ratings of Perceived Exertion (RPE and CR-10) and lactic acid plasma concentration as a biological marker of the effort performed. 13 male judo fighters who participated in a sports club competition provided capillary blood samples to assay lactate concentrat…
Sports, Executive Functions and Academic Performance: A Comparison between Martial Arts, Team Sports, and Sedentary Children
2021
It is well known that curricular physical activity benefits children’s executive functions and academic performance. Therefore, this study aimed to determine whether there is an influence of extracurricular sports on executive functions and academic performance. However, it is less known which specific types of the sport better enhance executive functions in children
Development of a Taekwondo Combat Model Based on Markov Analysis
2019
The purpose of the present study was to examine male and female Olympic taekwondo competitors' movement patterns according to their tactical actions by applying a Markov processes analysis. To perform this study, 11,474 actions by male competitors and 12,980 actions by female competitors were compiled and analyzed. The results yielded 32 significant sequences among male competitors and 30 among female competitors. Male competitors demonstrated 11 sequences initiated by an attack, 11 initiated by a counterattack, and 10 initiated by a defensive action. Female competitors demonstrated nine sequences initiated by an attack, 11 initiated by a counterattack, and 10 initiated by a defensive move.…

The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Use of heart rate variability in monitoring stress and recovery in judo athletes
2013
The main objective of this study was to examine the effect of different judo training loads on heart rate variability (HRV) measurements, to determine if they can be used as valid indicators in monitoring stress and recovery in judo athletes. Fourteen male national-standard judo athletes were randomly divided into 2 groups, and each group followed a different type of training, namely, a high training load (HTL) and a moderate training load program (MTL). Data collection included HRV measurements, a Recovery Stress Questionnaire for athletes (RESTQ-SPORT), and strength measurements, 4 weeks before and after the training program. The HTL group had lower square root of the mean squared differe…
Reflexive Modernization and the Disembedding of Jūdō from 1946 to the 2000 Sydney Olympics
2004
This article considers some of the sociologically significant changes to jūdō in its process of transformation from a Budō based martial art into a modern competitive spectator sport. Taking the period of time from 1946 until the Sydney Olympics, an examination is undertaken using Giddens’s notion of reflexive modernization in which key aspects of the original jūdō are disembedded or ‘lifted out’ of the practice. They are then re-embedded with western structures, practices and meanings. Central themes to emerge from this analysis are the social forces of internationalization, institutionalization and commodification of jūdō over this period, each of which contributes to a reflexive moderni…
Influence of Vertical Dimension of Occlusion on Peak Force During Handgrip Tests in Athletes
2018
Background: In contact sports, such as martial arts, protection from oral injuries is generally recommended. Several authors have focused on the effects of wearing such oral protective gear on sports performances and, in particular, occlusal devices. Although many studies have shown improvements in athletic performance, especially in maximal isometric strength, to date there is still no consensus on the issue. Objectives: The aim of our study was to evaluate differences in isometric handgrip before and after the application of an occlusal splint (OS) in martial arts athletes. Methods: A repeated measures within-subjects design was adopted for the study. Twenty-five young martial arts athlet…

Judo as a tool for social integration in adolescents at risk of social exclusion: A pilot study
2020
Purpose: Social policies of the advanced countries have begun to incorporate sport to speak on manifestations of social exclusion, as tool to reach out to young people, strengthen their identity or enhance self-esteem vulnerable groups. Judo can be a good tool for the fulfilment of this purpose because has a philosophy and educational practice that contains much of the core competencies of the educational system. The aim of this study is to analyse the incidence of judo practice in changing attitudes, values, norms and capabilities across organizational forms as a means of enhancing socialization in their interventions with young people at risk of social exclusion. Material/Methods: We used…
‘Strong and courageous’ but ‘constantly insecure’: dialogical self theory, intersecting identities, and Christian mixed martial arts
2021
Being a mixed martial arts fighter and a devout Christian seems to present an apparent contradiction that requires identity work to bring these identities into unity. We used Dialogical Self Theory and explored the autobiography of Ron ‘H2O’ Waterman, a professional fighter turned evangelist, to understand how the tensions between the different identities or I-positions were negotiated. We identified two I-positions, ‘Ron the Fighter’ and ‘Ron the Pater Familias’, which related differently to religion, sport, and masculinity. Importantly, the negotiations were not between MMA and faith, but between these two I-positions that served the different needs for self-enhancement and union with som…
