## 4 Discussion  
This study aimed to assess the anaerobic status of young male competitive judokas using the upper body Wingate test and explore associations with competition performance and individual morphological characteristics. However, no significant associations were found between competition performance and young male judokas' morphological or anaerobic characteristics. At the same time, several significant correlations were observed between morphological and anaerobic variables, with variables age and absolute skeletal muscle mass having the most significant associations with each other. These outcomes highlight that body composition and anaerobic performance are not key factors in young male judokas for success. According to the morphological data from Table 1, the height of Slovenian judokas in our sample shows similar height values compared to other studies on Slovenian judokas in the youth categories (176.5 \(\pm\) 6.6 cm vs. 176.5 \(\pm\) 9.7 cm). Similarity is also seen in body mass (75.5 \(\pm\) 15.8 kg vs. 72.0 \(\pm\) 7.3 kg) [64]. Compared to Spanish judokas in the same age categories, Slovenian judokas have similar physical characteristics: body mass (74.4 \(\pm\) 9.7 kg vs. 75.5 \(\pm\) 15.8 kg); body height (174.0 \(\pm\) 5.0 cm vs. 176.5 \(\pm\) 6.6 cm); body mass index (24.4 \(\pm\) 2.9 kg/m\({}^{2}\) vs. 24.1 \(\pm\) 3.8 kg/m\({}^{2}\)); body fat (10.3 \(\pm\) 6.6 kg vs. 8.9 \(\pm\) 8.6 kg); skeletal muscle mass (38.0 \(\pm\) 5.7 kg vs. 40.8 \(\pm\) 2.2 kg) [22]. Slovenian judokas also have similar physical characteristics compared to Slovenian judokas, with a body mass of 75.5 \(\pm\) 15.8 kg vs. 76.2 \(\pm\) 8.4 kg and a body height of 176.5 \(\pm\) 6.6 cm vs. 177.00 \(\pm\) 6.2 cm [65]. Research comparing the present study's data to Polish judokas has also shown similar physical characteristics: body mass (75 \(\pm\) 9.4 kg vs. 75.5 \(\pm\) 15.8 kg); body height (178.6 \(\pm\) 6.3 cm vs. 176.5 \(\pm\) 6.6 cm); body fat (7.4 \(\pm\) 2.8 kg vs. 8.9 \(\pm\) 8.6 kg); skeletal muscle mass (38.4 \(\pm\) 4.9 kg vs. 40.8 \(\pm\) 2.2 kg) [66]. From this, we could conclude that young Slovenian male judokas have similar physical characteristics as their peers from other countries who are competing in national and international competitions. From the body composition data, we can still see that there is room for body composition transformation via muscular hypertrophy without increasing body weight, while lowering adipose tissue [66]. The overall data in Table 5 show that the age variable is significantly positively correlated with six out of nine anaerobic variables. The research on 14-16-year-old boys training in judo has shown that this is the age of rapid anaerobic capacity development [67]. However, the data presented that the anaerobic features of young judokas are still developing in the U18 and U20 age competition categories. Additionally, absolute skeletal muscle mass correlated with five out of nine variables. This highlights the importance of increased muscle mass for young judokas' anaerobic development. Body height showed significant positive correlations with average power (AP; \(p\) = 0.02) and absolute anaerobic capacity (AAC; \(p\) = 0.02). This is in line with previous research on young judokas [68]. This could be explained by taller athletes being connected to higher body mass, which is related to increased skeletal muscle mass. It was reported that SMM increases linearly up to 120 kg in athletes and then reaches a plateau [69].
