After 2016 the International Judo Federation changed rules to promote the "positive" judo. This study compared two World Championships editions before and after the rules changes: Astana-2015 and Budapest-2017. Data from matches disputed in Astana (765) and Budapest (768) were analyzed concerning: total match duration, frequency of scores and penalties, association between edition and extra-time, disqualifications and matches without penalties. Three-way ANOVA was used to compare sexes, weight categories and World-Championships-edition, with Fisher's Least Significant Difference (LSD) test as post-hoc. The associations between World-Championships-edition and matches finished in extra-time, disqualifications and matches without any score were tested via Chi-square. Results were: (a) no change in number of ippon when the same sex and weight category were considered across years; (b) number of waza-ari increased from Astana to Budapest; (c) number of penalties decreased from Astana to Budapest. Females in Budapest received less penalties than females in Astana and males in both competitions. Extralightweights received less penalties than lightweights upwards; heavyweights received more penalties than all other weight categories from middleweights downwards; (d) occurrence of extra-time and hansoku-make increased for females, males and all groups together; (e) males' matches were longer than females ones. Thus, the new rules partially achieved the goal proposed.

Judo has developed in Britain over a period of approximately sixty years, during which time the scale of activity, the organisational form, the nature of pedagogic processes and the content of rules have changed considerably.

Watching the seemingly effortless combination of grace, technique and power of a true judo expert in action it would be very easy (but very wrong) to underestimate the intense physical and mental demands that judo makes upon its exponents. Achieving excellence in judo demands considerable single-mindedness, and achieving mastery of all of the throwing, grappling and striking techniques that makes up the discipline demands serious and arduous training over an extended period of time under the guidance of an experienced and knowledgeable teacher.

Judo Idokan w odniesieniu do Judo Kodokan (1947-2017): uwagi o instytucjonalizacji sztuk walki Streszczenie W dobie globalnego upowszechnienia się sztuk walki i sportów walki, także tych z Azji Wschodniej, judo jest wyraźnym przykładem udanej globalizacji sportu narodowego. W zasadzie nikt nie wątpi, że dotyczy to popularnego japońskiego sportu, który jest zarządzany przez jedną międzynarodową federację, a cały świat rywalizuje w turniejach mistrzowskich i igrzyskach olimpijskich. Czy jednak naprawdę istnieje tylko jeden rodzaj judo? I czy jest to tylko rozumiane jako ta dyscyplina sportu? Autor przytacza fakty pokazujące proces równoległej instytucjonalizacji innego judo, występującego pod różnymi nazwami. Najpierw jest to judo "europejskie" / judo-do, potem judo Kodokan lub Butokukai, uzupełnione technikami samoobrony jujutsu (jap. jūjutsu) i wreszcie dzisiejsze judo Idokan. Organizacja Idokan od ponad 70 lat uczy także szeroko rozumianego judo jako różnych metod sztuki walki kierujących się zasadą elastyczności. Słowa kluczowe: judo, judo-do, Idokan, Kodokan.

The purpose of this study was to construct knowledge test on history and rules of Judo. Fifty students of Master of Physical Education form the School of Physical Education, Devi Ahilya University, Indore in 2005-06 session, were selected to serve as subjects. A 100 items objective test was first administered to ten students in order to determine clarity of question items and on that basis the question items were refined and subjected to careful analysis. Then a second trial run of the question items was administrated to 50 students, which they answered in the allotted time of 60 minutes. These sheets were then evaluated. Six items were eliminated on the basis of difficulty rating and 29 items were discarded on the basis of index of discrimination. Thus a total of 30 items were discarded for various reasons and the final test therefore contained seventy questions.
