 note = {A rule prohibiting competitors from grabbing their opponents below the belt was implemented by the International Judo Federation in 2013. The current study discusses this rule’s effects on gripping techniques used by competitors through a comparison of score rates before and after the rule revision. The comparison is based on characteristics of grabs preceding scored throws performed in competitive matches and on the competitors’ gender and the weight class. Matches from four contests, the 2012 and 2013 Grand Slam Tokyo and the 2012 and 2013 Grand Slam Paris, were analyzed. All data relating to competitors’ use of grabbing techniques were confirmed unanimously by the three analysts as part of the validation process. The results indicate that re-gripping prior to throwing resulted in a significantly higher score rate in the men’s 100kg weight category while a significantly higher score rate was achieved by competitors who did not attempt to re-grip their opponent prior to throwing them in the women’s 52kg weight category. Based on this study’s findings, the 2013 rule revision affected men and women’s strategies in different ways.},
