“…Technical-tactical differences between male and female judokas have been shown ( Brito, Aedo-Muñoz & Miarka, 2020 ) in extra light and lightweight women categories as they had shorter accumulated attack times compared with their male counterparts ( Sterkowicz-Przybycień, Miarka & Fukuda, 2017 ). It was reported that in World championships, the percentage of matches completed before the official duration was higher in female categories when compared to males ( Ceylan & Balci, 2021 ).…”

Background Judo, as a high-intensity contact sport, may lead to the occurrence of injuries, especially in competitions. This work aims to assess the likelihood of soft and hard tissue injuries in top-level judokas during competition with defining factors that determine the probability of injury occurrence. Methods The injuries that occurred in 123 official international competitions from 2005–2019 were recorded by the European Judo Union (EJU) Medical Commission as a survey that was a part of the EJU Injury Registration form with internal consistency shown by a Crombach Alpha of 0.69. This survey data identified factors such as: sex, anatomical localisation of injury, type of injury, tissue involved and mechanisms of the injury. A total of 650 tissue injuries were reported correctly in terms of tissue injury definition. Results The most frequent soft tissue injury (STI) reported was a ligament STI (48.15%), closely followed by skin STI (12.15%) and muscles STI (11.38%). In turn, the most frequent hard tissue injury occurred in bones (8.56%). The highest rates of injuries occurred during the fight in the standing position (78%). Injuries in the standing position mainly occurred while executing a throw (25.85%) and followed by the attempt to throw, i.e., the action of reaching the throwing position (22.30%), grip fighting (15.07%), and during falls (14.77%). Opposite to this, fight in groundwork reached only 18.30% soft and hard tissue injuries combined. The ongoing registration of injuries during judo combat and training and the early diagnosis of risk factors for injuries are the basis for the development of effective strategies for injury prevention and further treatment.

“…On the other hand, collar and sleeve grips (69.9%), followed by back-number (15%) and in other areas (15%) scored more when there was no grip reconfiguration (Ito et al, 2019). Additionally, Brito et al (2020) proposed gripping locations on the right and left sides of the collar, sleeve and dorsal.…”

In judo combat, the grip (kumi-kata) helps to control and to dominate the opponent, and per the current rules is a prerequisite to executing a throwing technique. In this scoping review, articles and reviews published in scientific journals in English were searched in Web of Science, Scopus, PubMed and SPORTDiscus databases from inception until December 2020. The studies were classified into technical-tactical or time-motion analyses, grip or grip attempts, grip locations on uke´s (athlete receiving the attack) judogi (judo uniform) or hands that performed the grips, and one or two hands holding. Articles evaluating the physical and physiological capacities of grip dispute were excluded. From 286 articles identified, 41 were included in the final selection. Two reviewers screened the records independently for eligibility. One reviewer extracted all data and the other reviewed the data for accuracy. The main results showed that: i) more experienced athletes hold the judogi for less time before attacking and focus their vision on the face and collar; ii) male athletes, especially heavy ones, hold longer in the judogi and use more defensive grips (collar and collar); iii) the most used grip was collar and sleeve; iv) the most used position was kenka-yotsu (opposite sides). The result of this scoping review may assist coaches and athletes to develop training strategies according to the athletes’ technical-tactical objectives, as well as future investigations that can be conducted related to grip dispute in judo.

“…Notational analysis is concerned with identifying patterns, often referred to as 'performance indicators', in the judo competitive environment (Brito et al, 2017;Ito et al, 2015). While match demands have been well-described in judo using time-motion (Barreto et al, 2019;Brito et al, 2020;Challlis et al, 2015;Dudeniene et al, 2017;Miarka et al, 2016;Miarka et al, 2016a;Soriano et al, 2019;Sterkowicz-Przybycień et al, 2017), technical-tactical analysis (Calmet et al, 2006;Klys et al, 2020), muscle group specific torque production (Brito et al, 2020;Lech et al, 2015), motor actions (Courel-Ibáñez et al, 2014;Del Vecchio et al, 2018;Calmet et al, 2010;Franchini et al, 2018;Ito et al, 2014;Kajmovic & Radjo, 2014;Miarka et al, 2017;Piras et al, 2014), and biomechanical analysis (Soto et al,2020;Dal Bello et al, 2019;Ito et al, 2019), a practical performance analysis Escobar-Molina et al, 2014) to verify how rules changes between 2010 and 2020 impacted in judo is needed to evaluate contextual information during judo competition (Soto et al, 2020a;Miarka et al, 2015;Tamura et al, 2012).…”

This study aimed to describe and analyze the main changes in the official competitive rules of judo between 2010 and 2020, highlighting changes in combat time, scores and penalties. In this retrospective study, a search was performed for official documents which regulated judo rules between 2010 and 2020 on the websites of the International Judo Federation and the Brazilian Judo Confederation, as well as refereeing manuals of the Sergipe Judo Federation (Brazil) and on the Google platform. Over the years, regular combat time has been shortened (2015=5’->4’ for women; 2017=5’->4’ for men), as well as osaekomi time (2013=25”->20”). This change was intended to facilitate the public’s understanding of judo scores, as well as to devalue the use of penalties to achieve the victory (2010=koka’s exclusion; 2013=penalty was no longer worth scores; 2017=yuko’s exclusion, shido no longer decided the winner in regular time; 2018=shido no longer decided the golden score winner). Attack actions were encouraged (ban on actions to flee combat) and there was an intention to reduce the risk of injuries in competitive judo (prohibition of some types of actions and grips). In other words, there was an attempt by the International Judo Federation to encourage positive judo through the rules from 2010 to 2020. However, these constant rule changes made the competitive training context unstable. Judo coaches and athletes must be aware at the end of each Olympic cycle for new changes which will eventually be introduced and adapt to them quickly to achieve high performance.
