<p>This study aimed to demonstrate the effect of successive stages of high-level judo competitions on match outcome and the factors effecting it. A total of 4550 official matches in both men and women were included in the analysis. Frequencies and percentages were used for descriptive statistics. Mean and standard deviations with 95% confidence intervals were also presented. The difference in the variables investigated for each stage of judo competitions was analysed with the Chi-square test. Continuous variables were analysed with the Kruskal-Wallis test. The way competitors won a match differed in elimination, final stages, and medal matches (<em>p</em>=.02). When the difficulty of the matches increased, the percentage of the matches ended with <em>ippon </em>decreased and the percentage of the matches resulted with <em>waza-ari</em> increased. The percentage of the matches without any <em>shido</em> decreased from the elimination to the finals while there was a significant increase in the percentage of the matches with s<em>hido </em>(<em>p</em>=.01). The match duration was found to increase from eliminations to the finals (<em>p</em>=.00). The efficiency index of the winner athletes during the first stage was higher than the other stages (<em>p</em>&lt;.05). In conclusion, high-level judo athletes won a match with different scores at different stages during high-level judo competitions. Moreover, athletes were awarded with penalties more during the finals compared to eliminations, and match duration incrementally increased from the eliminations to the finals.</p>

In judo tournaments, matches for each weight category are held on the same day and athletes competing at the finals have to compete at different times of the day. This study aimed to investigate the effect of time-of-day on judo specific performance and the changes in physiological load following judo specific performance. Fourteen male judo athletes (age 19.1±1.4 years) voluntarily participated in the study. At the 1st visit, anthropometrical measurements and familiarization procedures were conducted and the athletes’ chronotype was determined. Athletes performed the Special Judo Fitness Test (SJFT) during 2nd and 3rd visits. Athletes randomly performed two consecutive SJFTs with 15 min intervals at 10:00h, which is the official start time of matches, and at 18:00h which is the time when the finals start. During SJFT applications, athletes heart rate (HR), blood lactate (bLA), body temperature and rate of perceived exertion (RPE) were monitored. The changes in total throw numbers (F1, 13= 1.32, p=0.27) and SJFT index (F1, 13= 0.30, p=0.59) were not different between morning and evening. There were similar changes in bLA (F4, 52=0.66, p=0.63), RPE (F1, 13=1.42, p=0.26) and body temperature (F1.4, 18.0=1.18, p=0.31) which were measured before and after the tests. However, HR measured in the evening were higher compared to morning measurement at all measurement times (F1, 13=10.28, p=0.01), but there was no difference in SJFT throws (F3.8, 48.8=0.49, p=0.74). In conclusion, different times of the day did not affect judo specific performance as well as physiological variables in judo athletes.

Araştırmada wingate anaerobik testinde (WAnT) yükün, test süresinin ve cinsiyetin güç çıktılarına etkileri incelendi. Araştırmaya, 14’ü kadın 33 orta düzeyde aktif genç yetişkin katıldı (yaş; 20.9±1.8 yıl). Katılımcılar laboratuvarı 7 kez ziyaret etti. İlk ziyarette vücut kompozisyonu ölçümleri ve adaptasyon çalışmaları yapıldı. Sonraki 6 ayrı ziyarette ise vücut ağırlıklarının % 8,5’ine ve yağsız vücut kütlesinin %11’ine göre verilen yüklerde en az 2 gün arayla sıra takip etmeksizin 15 sn, 20 sn ve 30 sn WAnT uygulamaları yapıldı. Cinsiyetin WAnT güç çıktılarına etkisi split-plot ANOVA ile incelendi. Anlamlılık düzeyi p
