Introduction: Over the years, there has been an increase in the prevalence of Autism. It has been shown that martial arts are an effective intervention in controlling the symptoms of children and ...adolescents. However, there needs to be reviews that focus on synthesizing this evidence. Objective: Synthesize the current information on the effects and characteristics of carrying out martial arts programs and their effects on autistic traits in children and adolescents. Methodology: Systematic review that adheres to the Prisma 2020 declaration. The search was carried out in the Scielo, PubMed, Pedro, Cochrane Library, ProQuest, Springer Link, Web of Science, and ScienceDirect databases, and randomized and non-randomized clinical trials were selected. Results: Martial arts as a therapeutic intervention had statistically significant beneficial effects on stereotyped behavior 100% (5 of 5 studies), social interaction 100% (3 of 3 studies), emotion management 100% (3 of 3 studies), regulation of behavior 75% (3 of 4 studies), behavioral problems 75% (3 of 4 studies) and difficulty communicating 75% (3 of 4 studies). The most widely used martial art as a therapeutic intervention program was karate. Conclusion: The most evaluated areas in autistic treats are stereotyped behaviors, behavioral problems, social interaction, and communication difficulties. Finally, it was observed that the martial arts programs had favorable effects on ASD symptoms in behavioral, social, and communication skills.
Introducción: La prevalencia del autismo se ha incrementado significativamente. También, se ha evidenciado que las artes marciales son una intervención efectiva en el control de la sintomatología de niños, niñas y adolescentes con TEA. Sin embargo, no existen revisiones enfocadas en sintetizar esta evidencia. Objetivo: Sintetizar la información existente sobre las características de los programas de artes marciales y sus efectos sobre rasgos autistas en niños y adolescentes. Metodología: Revisión sistemática que se adscribe a la declaración Prisma 2020. La búsqueda de información se realizó en las bases de datos Scielo, PubMed, Pedro, Cochrane Library, ProQuest, Springer Link, Web of Science y ScienceDirect. Se seleccionaron Ensayos clínicos aleatorizados y no aleatorizados. Resultados: Las artes marciales como intervención terapéutica tuvieron efectos beneficiosos estadísticamente significativos en conductas estereotipadas 100% (5 de 5 estudios), interacción social 100% (3 de 3 estudios), manejo de las emociones 100% (3 de 3 estudios), regulación de la conducta 75% (3 de 4 estudios), problemas conductuales 75% (3 de 4 estudios) y dificultad para comunicarse 75% (3 de 4 estudios). El arte marcial más utilizado como programa de intervención fue el karate. Conclusión: Las áreas más evaluadas en los rasgos autistas son las conductas estereotipadas, problemas conductuales, interacción social y dificultad de la comunicación. Finalmente se observó que los programas de artes marciales tuvieron efectos favorables en rasgos autistas en áreas de habilidades conductuales, habilidades sociales y habilidades comunicativas.
Introduction. A coach compiles and determines a training program based on the physical fitness profile of the athlete. Central Sulawesi taekwondo and karate athletes have been undergoing independent ...training since mid-2020.
Objective of the study. This study aims to investigate the comparison in physical fitness of elite athletes in taekwondo and karate
Research methods. This study uses a causal-comparative method, where the researcher seeks to determine the cause or effect of the differences that occur between groups. The sample of this research is 20 elite athletes. Evaluation of physical abilities or physical fitness is an instrument used to measure the physical fitness of taekwondo and karate athletes. An independent sample t-test was used for comparison of independent samples.
Research result and Conclusion. The results and conclusions of the study indicate that descriptively the speed, endurance of abdominal muscle strength, and endurance of thigh muscle strength, agility, flexibility, leg reaction speed, and cardiovascular endurance of taekwondo athletes are higher than karate athletes, while for leg muscle strength and breathing karate athletes are higher than taekwondo athletes. Sig value. (2 tailed) or p-value <0.05, it can be concluded that there is a significant difference in the variable components of physical fitness, abdominal muscle strength, agility, flexibility in leg reaction speed, and cardiovascular endurance between taekwondo athletes and karate athletes. Whereas in the variable components of physical fitness, speed, endurance, thigh muscle strength, and leg and respiratory muscle strength, there were no significant differences between taekwondo athletes and karate.
Background:
Prospective studies on injuries in martial arts competition are scarce, especially those involving young practitioners, but the upsurge of children and adolescents taking part in ...organized training and competition in these sports requires clarification of the injury risk that they represent for youths.
Hypothesis:
Top-level karate competition for young adolescents (cadets, or 14- to 15-year-olds) has a low injury rate and can be safely promoted.
Study Design:
Descriptive epidemiological study.
Methods:
Prospective recording of the injuries resulting from all bouts in 3 consecutive World Karate Championships (2009, 2011, and 2013) for cadets was performed. Data were collected prospectively in situ with checklists that described competitor sex, bout category, and weight as well as injured area, diagnosis, mechanism of injury, severity, and treatment.
Results:
A total of 1020 bouts were reviewed, 671 in the male category and 349 in the female category. A total of 61 injuries were recorded. Of those, only 3 were time-loss injuries. During the 2009 and 2011 championships, there was 1 injury per 25.6 fights, while during the 2013 championship the number of injuries increased, with 1 injury per 10 fights (P = .003). There was no statistical difference in the total injury rate between the male and female categories (P = .71), with an odds ratio of 1.16 (95% CI, 0.52-2.55).
Conclusion:
The injury rate for cadet top-level karate competition found in this prospective study is much lower than the rates previously published for karate or other martial arts competitions, but there seems to be a marked increase as more championships are held, which is a matter of concern.
El presente artículo se precisan los principales conceptos relacionados con la táctica en el kumite del karate do categoría escolar, por consiguiente, va dirigido hacia el estudio de la preparación ...táctica, específicamente hacia la determinación de las acciones o fases de la táctica, así como los diferentes métodos de la preparación táctica, sus y pensamiento táctico; el análisis de los principios para la evaluación de la táctica en los deportes de oposición y la concepción de los diferentes tipos de kumite en el karate-do, como aspectos más complejos de la preparación del karateca, lo cual constituye de gran importancia. para el mismo fue necesario el empleo de varios métodos de investigación entre ellos el análisis síntesis el cual permite analizar la literatura consultada y llegar a consideraciones sobre el tema de igual manera el empleo de la inducción deducción permitió arribar a conclusiones.

During a karate competition, a competitor in the kata discipline may choose one kata of 102 katas on the list. This kata must not be repeated. Katas differ in duration, complexity, number of fast and ...slow techniques, which also means different intensity, physiological response of the karateka body and energy coverage.
In our study, we focused on the identification and assessment of the duration and difficulty of selected katas by monitoring the internal response of the human body (heart rate, lactate) of three top women´s Slovak national team karate competitors of kata individual categories during training and competition.
The research sample consisted of 3 karate kata athletes (age 17.3 years, body height 161.7 cm, body weight 55.7 kg), who trained kata on average 7 years. To evaluate the indicators of the internal body load in selected katas we used mean, standard deviation, min-max.
The highest mean maximum heart rate values athletes had during performance kata Gojushi Ho (187 ± 8.2 bpm). The highest average heart rate values were observed during performance kata Chatanyara Kushanku (171 ± 9.9). Similarly, we found the highest mean values of blood lactate 4 minutes after performance kata Chatanyara Kushanku. (7.6 ± 2.5 mmol.l
). The longest duration had the kata Suparinpei (204 ± 13 s). There was a significant difference in level of blood lactate reached in different katas (p ≤ 0.05) and the duration of katas.
The duration of 5 most common katas used at the high level competition is different (p ≤ 0.05), thus the intensity expressed by the frequency of the techniques, and heart rate and blood lactate concentration. ATP-PCr energy system seems to be the major contributor while contribution of the aerobic energy system rises with the increase in duration of kata.
Network science is an interdisciplinary endeavor, with methods and applications drawn from across the natural, social, and information sciences. A prominent problem in network science is the ...algorithmic detection of tightly connected groups of nodes known as communities. We developed a generalized framework of network quality functions that allowed us to study the community structure of arbitrary multislice networks, which are combinations of individual networks coupled through links that connect each node in one network slice to itself in other slices. This framework allows studies of community structure in a general setting encompassing networks that evolve over time, have multiple types of links (multiplexity), and have multiple scales.
Systematic sport practice at younger ages positively influences body composition and maximum oxygen uptake (VO2max). On the other hand, its influence on maturation is still not consensual, and some ...studies claim a negative effect. Few studies have approached the differences in this influence according to different sport practices. The present study aims to analyse and compare the influence of karate and swimming practices, and the non-practice of sports, on body composition, VO2max and maturation in children and youth. Data were collected in 126 youth, 54 karate athletes, 36 swimming athletes and 36 participants with no sport practice (M=11.56±2.06 years). The type of sport practice had a different influence on body composition and VO2max, no negative influence was verified on maturation. In general, the sport practices revealed a positive influence in children and youth’s body composition. The karate practice provided significant lower body fat mass and higher lean mass in males. Swimming athletes revealed a significant higher VO2max compared to all other groups, while karate didn´t differed from no-practice group. The different influence of sport practices verified highlighted the importance of a multilateral development of children and youth by practising several sports.
Resumen: La práctica deportiva sistemática a edades más tempranas influye positivamente en la composición corporal y la absorción máxima de oxígeno (VO2max). Por otro lado, su influencia en la maduración aún no es consensuada, y algunos estudios afirman un efecto negativo. Pocos estudios se han acercado a las diferencias en esta influencia según las distintas prácticas deportivas. El presente estudio tiene como objetivo analizar y comparar la influencia de las prácticas de kárate y natación, y la no práctica de deportes, sobre la composición corporal, el VO2máx y la maduración en niños y jóvenes. Los datos fueron recolectados en 126 jóvenes, 54 atletas de kárate, 36 atletas de natación y 36 participantes sin práctica deportiva (M = 11.56 ± 2.06 años). El tipo de práctica deportiva influyó de manera diferente en la composición corporal y el VO2max, no se verificó influencia negativa en la maduración. En general, las prácticas deportivas revelaron una influencia positiva en la composición corporal de niños y jóvenes. La práctica del karate proporcionó una masa grasa corporal significativamente más baja y una masa magra más alta en los hombres. Los atletas de natación revelaron un VO2max significativamente más alto en comparación con todos los demás grupos, mientras que el karate no difirió del grupo sin práctica. La diferente influencia de las prácticas deportivas verificada resaltó la importancia de un desarrollo multilateral de la niñez y la juventud a través de la práctica de varios deportes.
