ABSTRACT
Objective: This study aimed to determine the effects of sex and weight category on points, penalties, and match efficiency index after recent rule changes implemented between 2018-2020. Material and Methods: The data were obtained from a total of 1,664 matches. The effects of sex and weight categories on total match duration, match efficiency index scores for each athlete per match, the number of ippon, waza-ari, and penalties were tested with a two-way analysis of variance. Chi-square test was used to verify the relationship between sexes, match duration percentages, and percentages of the matches with and without the golden score. Significance was set at p<0.05. Results: Match durations and efficiency index scores were not affected by sex and weight category. However, the percentage of matches completed before the official duration in women was found higher than men. The duration of the matches decreased when the weight category increased for both sexes. When the weight category increased, the number of ippons increased, and the number of waza-ari decreased. The number of waza-ari was found higher in women compared to men. Interaction of sex and weight category on shido was found to be significant. The number of shido was higher in women and it increased with the increase in weight categories. Conclusion: It can be inferred from the study that the weight category factor affected ippon and waza-ari scores in the Senior World Championships. Although match efficiency score and total match duration were the same in men and women, women had a greater number of scores and penalties compared to men.

ÖZET
Amaç: Bu çalışma, 2018-2020 yılları arasında yapılan son kural değişiklikleri sonrasında cinsiyet ve ağırlık kategorisinin puan, ceza ve maç etkinliği indeksi üzerindeki etkilerini belirlemeyi amaçlamaktadır. Gereç ve Yöntemler: Veriler toplam 1.664 maçtan elde edildi. Cinsiyet ve ağırlık kategorilerinin; toplam maç süresi, maç başına her sporcu için maç verimlilik indeksi skorları, ippon sayısı, waza-ari ve cezalar üzerindeki etkileri 2 yönlü varyans analizi ile test edildi. Altın puan ile biten ve bitmeyen maçların yüzdeleri, cinsiyetler ve maç süresi yüzdeleri arasındaki ilişkiyi doğrulamak için ki-kare testi kullanıldı. İstatistiksel önemlilik p<0,05 olarak belirlendi. Bulgular: Maç süreleri ve etkinlik indeksi puanları, cinsiyet ve ağırlık kategorisinden etkilenmedi. Ancak kadınlarda resmi süreden önce tamamlanan maçların yüzdesi, erkeklerden daha yüksek bulundu. Her iki cinsiyette de kilo kategorisi artıkça maçların süresi azaldı. Kilo kategorisi artınca ippon sayısı arttı, waza-ari sayısı azaldı. Waza-ari sayısı kadınlarda, erkeklere göre daha yüksek bulundu. Cinsiyet ve ağırlık kategorisinin, shido üzerindeki etkileşimi önemli bulunmuştur. Kadınlarda, shido sayısı daha fazlaydı ve kilo kategorilerindeki artışla arttı. Sonuç: Çalışma sonucu, ağırlık kategorisi faktörünün Büyükler Dünya Şampiyonaları'nda ippon ve waza-ari puanlarını etkilediğini ileri sürmektedir. Maç etkinlik skoru ve toplam maç süresi, kadınlarda ve erkeklerde aynı olmasına rağmen kadın sporcular erkeklere göre daha fazla puan ve ceza aldılar.
