### Descriptive Analysis of Scoring Actions
Most scoring actions occur when the judoka uses a lapel-sleeve grip, accounting for 60.9% of the actions. The sleeve-back grip is the second most common, with 15.3%. Other grips do not exceed 7% individually. The distribution of scoring actions according to the grip of the non-scoring judoka is homogeneous across the different weight categories, as no significant differences were found (\(\chi^{2}=60.953\), \(p=0.441\)). The majority of scoring actions occur when the judoka uses a lapel-sleeve grip, accounting for 78.9% of the actions. The sleeve-back grip is the second most common, at 6.9%. The other grips do not exceed 5% individually. The distribution of scoring actions based on the movement of the scoring judoka has shown to be heterogeneous across different weight categories, with significant differences observed (\(\chi^{2}=75.939\), \(p=0.026\)). The effect size test indicated that the relationship was moderate (\(V=0.220\)). In general, the majority of scoring actions occur in a static position, accounting for 47.1% of the total. Tai sabaki is the next most common movement, representing 22.6%. Notably, in the \(-81\) kg category, actions in tai sabaki exceed those in a static position (corrected residual 3.6), while in the \(-100\) kg category, they are very similar. The distribution of scoring actions based on the movement of the non-scoring judoka is heterogeneous among the different weight categories, with significant differences observed (\(\chi^{2}=75.939\), \(p=0.026\)). The effect size test indicated that the relationship was moderate (\(V=0.220\)). Generally, most scoring actions occur when the judoka is stationary (47.1%), followed by actions in tai sabaki (22.6%). Notably, in the \(-81\) kg category, the actions in tai sabaki exceed those in a static position (corrected residual 3.6), while in the \(-100\) kg category, they are very similar. The distribution of scoring actions based on the technique group used by the scoring judoka is heterogeneous among the different weight categories. Significant differences were found (\(\chi^{2}=51.551\), \(p=0.0004\)). The effect size test indicated a moderate relationship (\(V=0.257\)). In general, there is a similar average usage among the groups of te waza, ashi waza, and sutemi waza, with koshi waza being the least utilized. By weight categories, clear differences are observed. In the 73 kg category, arm techniques are the most frequently used (adjusted residual 2.2), while leg techniques are the least utilized (adjusted residual \(-2.6\)). In the 81 kg category, hip techniques are more common (adjusted residual 5), while arm techniques are less utilized (adjusted residual \(-\)2.8). In the 90 kg category, leg techniques are the most frequently used (adjusted residual 2.5). The distribution of scoring actions based on the technique used by the scoring judoka was heterogeneous across different weight categories. Significant differences were found between them (\(\chi^{2}\) = 307.451, \(p\) = 0.001). The effect size test indicated a strong relationship (\(V\) = 0.443). Each technique is used differently in each weight category. In the 60 kg category, the most used techniques are seoi-nage, sumi-otoshi, and uchi-mata (all three with equal frequency), and o-soto-otoshi has a higher than expected frequency (adjusted residual 2.1). In the 66 kg category, the most frequently used technique is sumi-otoshi. Techniques like hiza-guruma, ko-soto-gari, ko-uchi-makikomi, and tsubame-gaeshi have a higher than expected frequency (all with adjusted residuals of 2.2), while uchi-mata has a lower than expected frequency (adjusted residual \(-\)2.3). In the 73 kg category, the most used technique is seoi-nage, which also has a higher than expected frequency (adjusted residual 3.7), as does kata-guruma (adjusted residual 2.8). In the 81 kg category, the most used techniques are koshi-guruma and uchi-mata (both equally frequent).
