This research aimed to clarify whether the International Judo Federation Refereeing Rules 2014-2016 (New-IJF Rules) facilitated dynamic judo in the All-Japan Judo Championships (AJJC). Therefore, Kodokan Judo Refereeing Rules’ tournaments (KDK Rules’ tournaments), International Judo Federation Refereeing Rules’ tournaments (IJF Rules’ tournaments), and New-IJF Rules’ tournaments were compared. The following results were obtained.
Regarding winning contents, in the New-IJF Rules’ tournaments wins by ippon significantly increased whereas wins by superior performance significantly decreased when compared to KDK Rules’ tournaments. Furthermore, for winning methods, points from techniques significantly increased but judges’ decisions significantly decreased in the New-IJF Rules’ tournaments when compared to KDK Rules’ tournaments. However, concerning total points, the results did not show significant differences.
As a result, this research confirmed that the New-IJF Rules increased the wins by ippon and points from techniques in relation to winning methods, and decreased the superior performance and judges’ decisions in the AJJC. These findings suggest that the New-IJF Rules facilitated dynamic judo in the AJJC.
