ABSTRACT
Objective: The purpose of this study is to examine the match-related performance (scores and penalties) of the athletes in the Junior European Judo Championship (EJC) and U23 EJC categories before and immediately after the coronavirus disease-2019 (COVID19) quarantine, according to gender and weight category groups. Material and Methods: Our sample was based on the junior and U23, male and females, 2019-2020 Junior EJCs and 2019-2020 U23 EJCs. A total of 1,431 matches in these tournaments were analyzed: male (n=812) and female (n=619). Results: The main findings of this study showed that most matches in both the male and female categories resulted in Ippon (2019-2020 average: 64.35% for Junior male, 70.55% for U23 male and 69.3% for Junior female, 64.4% for U23 female). No significant differences (p>0.05) were observed between gender and age groups concerning the match scores. Conclusion: In order to minimize performance losses in athletes in similar processes such as COVID-19, training programs should be carefully planned in terms of the number, intensity and scope of training, taking into account individual differences. It is worth noting that the frequency of buying Ippon for male and female has increased in post quarantine competitions; the reason for this situation may be not to prolong the match, to finish the match by taking Ippon early, or to preserve the energy as if he will compete at any moment. Therefore, judo athletes must be tactically prepared to face these situations.

ÖZET
Amaç: Bu çalışmanın amacı, gençler Avrupa Judo Şampiyonası [European Judo Championship (EJC)] ve U23 EJC kategorilerindeki sporcuların koronavirüs hastalığı-2019 [coronavirus disease-2019 (COVID-19)] karantinası öncesi ve hemen sonrasındaki maçla ilgili performanslarını (skorlar ve cezalar) cinsiyet ve ağırlık kategorisi gruplarına göre incelemektir. Gereç ve Yöntemler: Örneklemimiz, gençler ve U23, erkekler ve kadınlar, 2019-2020 Gençler EJC ve 2019-2020 U23 EJC'ye dayanmaktadır. Bu turnuvalardaki toplam 1.431 maç analiz edilmiştir: erkek (n=812) ve kadın (n=619). Bulgular: Bu çalışmanın ana bulguları, hem erkek hem de kadın kategorilerindeki maçların çoğunun İppon ile sonuçlandığını göstermiştir (2019-2020 X̄: genç erkekler için %64,35, U23 erkekler için %70,55, genç kadınlar için %69,3, U23 kadınlar için %64,4). Cinsiyet ve yaş grupları arasında maç puanları açısından anlamlı bir fark (p>0,05) gözlenmemiştir. Sonuç: COVID-19 gibi benzer süreçlerde sporcularda performans kayıplarını en aza indirmek için antrenman programları bireysel farklılıklar göz önünde bulundurularak antrenman sayısı, yoğunluğu ve kapsamı açısından dikkatli bir şekilde planlanmalıdır. Karantina sonrası müsabakalarda erkek ve kadınlarda İppon alma sıklığının arttığını belirtmekte fayda var; bu durumun sebebi maçı uzatmamak, erken İppon alarak maçı bitirmek ya da her an müsabakaya çıkacakmış gibi enerjiyi korumak olabilir. Bu nedenle judo sporcuları bu durumlarla karşılaşmaya taktiksel olarak hazırlıklı olmalıdır.
