| Özet |
| In 2016 the International Judo Federation (IJF) started to test new rules to promote the rules of judo and make them easier to understand as well as to simplify them. IJF stated that the purpose of these rules was to give priority to the attack and to the realization of ippons. Duration of the competition for both women and men was changed as 4 min. Points and penalties were rearranged; thus important changes were made (IJF Refereeing Rules 2017). The aim of this study was to compare the points and penalties before and after the rule changes in judo. The data were obtained from the judo world tour and ranking list website ( http://www. judobase. org). Archive data from this official site are open-access and there are no ethical issues involved in the analysis. The data were collected from the scoreboards directly, so includes any errors made by volunteer operators. The chi square test for linear trends in proportions was used to evaluate differences in the scores and penalties in Judo Grand Slam Paris between the 2016 and 2017. The odds ratio was used to estimate effect size. Statistical significance was set at a level of p< 0.05. The frequency of ippon and hansoku-make did not significantly change after the new rules in men and women (p> 0.05). The new rules caused to increase in wazari score for both group, while decreasing total number of shido only for men (p< 0.05). |
