      Abstract: Objective. To measure rapid weight loss and urinary indicators of hydration status, as well as to assess the effects and symptoms of dehydration in Brazilian jiu-jitsu (BJJ) athletes at different moments. Methods. 17 male BJJ athletes (aged: 24.4 ± 3.5 years; body mass (BM): 76.8 ± 14.6 kg; body fat: 16.6 ± 6.4%), were evaluated between 8 and 9 am at three different moments: Baseline (10 days pre- competition), measurement of BM and stature, collection of urine samples, and food record of the previous 24 hours; pre-competition, measurement of BM, urine samples, and questionnaire to assess rapid weight loss (RWL), and post-competition (24h after), day after competition, with measurement of BM, and urine samples for analysis of specific gravity. Results. There was a tendency to decrease BM to compete (baseline: 76.8 ± 14.6 kg, pre-competition: 75.4 ± 13.4 kg, post-competition: 77.3 ± 13.7 kg; p < 0.07), with 88.2% of athletes using methods that increase dehydration. The majority of athletes were dehydrated at the three time points of the study (94.1%; USG = 1.021 ± 0.005 Usg at baseline, 88.2%; 1.020 ± 0.007 Usg at pre-competition, 88.2%; 1.022 ± 0.008 Usg on the post-competition day), accompanied by symptoms associated with RWL (82.4% increased heart rate, 52.9% headache, 47.1% hot flashes, 41.2% nausea, 41.2% disorientation, and 29.4% dizziness). Conclusions. Rapid pre-competitive weight loss and symptoms associated with dehydration were observed in the BJJ athletes. It is recommended that educational measures are promoted to inhibit RWL among BJJ athletes, requiring the engagement of health professionals and organizations that govern the sport (federations and confederations).

  • The relationship between judo specific test performances and physical
           fitness in prepubescent male judo athletes

    • Authors: Ömer Faruk Demirci, Bayram Ceylan, Sükrü Serdar Balci
      Pages: 12 - 22
      Abstract: The aim of this study was to investigate the relationship between judo specific test performances and physical fitness of prepubescent judo athletes. Forty male judo athletes aged 10-13 voluntarily participated. Athletes completed special judo fitness test (SJFT), hikisdashi uchi-komi test (HUT), judogi grip strength tests, and performance-related physical fitness components tests (aerobic power, strength, agility, explosive power, body composition). Correlation coefficients were used to analyze the relationship between the judo specific tests and physical fitness performances. Significant correlations were found between total throw numbers during SJFT, HUT performance, isometric and dynamic judogi grip strength test performance and general performance-related physical fitness tests. Also, negative correlations were found between judo specific tests performances and body fat percent. It can be concluded from the study that total throws in SJFT, 20 s HUT and dynamic judogi grip strength tests can be used to monitor performances of prepubescent judo athletes as these tests present large significant correlations with performance related physical fitness tests.

  • A process-sociology analysis of religious practices and Japanese martial

    • Authors: Raúl Sánchez García
      Pages: 23 - 40
      Abstract: This paper uses primary and secondary sources to provide a process-sociological analysis of the relationship between religious practices and Japanese martial arts. It problematises the taken for granted role of Zen Buddhism as the sole influence on the development of Japanese martial arts. Such essential connection is inaccurate and anachronistic. Religious and martial practices developed as part of processes of sociogenesis (state formation) and psychogenesis (habitus) during three different key stages: (1) Medieval Japan (1185-1600): during this stage, warriors (bushi) progressively became the predominant rulers across the country, enforcing law by sheer force. Warriors seasoned in combat used esoteric practices (spells, magic rituals) as part of their psychological arsenal for warfare, as practical means of action. The cult of the Buddhist deity Marishiten held special interest for the bushi originating martial traditions (ryu). (2) Tokugawa shogunate (1600-1848): the pacification of the country by the central military court implied a more detached approach to martial arts by samurai. Within this milieu, the samurai acted as a retainer/bureaucrat whose main mission was to keep order in a stratified society and to serve his lord, something that Zen practices helped to incorporate in the samurai ethos. (3) Early Showa period (1926-1945): this stage featured a progressive militarisation of people and the instigation of a strong involvement towards the Japanese nation, considered as the main (symbolic) survival unit. Budo (martial arts) was connected to shinto (functioning as a ‘state religion’) and embodied the imperial bushido message. Zen provided a legitimation of violence for citizen-soldiers with a personality structure that presented self-doubts on killing someone and fear of being killed.

  • Traditional martial arts versus martial sports: the philosophical and
           historical academic discourse

    • Authors: Udo Moenig, Minho Kim, Hyun Min Choi
      Pages: 41 - 58
      Abstract: There have been a variety of attempts by scholars to neatly define and categorize Asian martial arts terminology, often in connection with martial arts history, philosophy, and practical training activities. Overall, the English term ‘martial arts’ is typically linked to East Asian fighting activities. In comparison, Western fighting methods, such as boxing and wrestling, are almost never referred to as ‘martial arts’ but mostly labeled ‘sports’ or ‘combat sports.’ This is reflected in the basic split of the broader martial arts community, which is between the so-called traditionalists and the modernists. The former often stress spirituality and mysticism and claim that the primary aim of martial arts is self-defense, while the latter are commonly affiliated with sports training and competitive events. The rift between the two camps is not settled and it represents the main reason of the many conflicting opinions and arguments articulated in the martial arts discourse. The principle method of this study is an extensive literature review with the aim to clarify the confusion by pointing out the many paradoxes present in the historical and philosophical narratives in connection with practical training activities of the martial arts. Besides, this article represents also a critique of the general, academic discourse about the Asian martial arts, which often appears disingenuous and is generally dominated by the traditionalists.
