The purpose of this master's thesis was to analyze judging consistency and the impact of key judging events on bout outcomes in Olympic boxing. We focused on inter-judge agreement in scoring individual rounds, the predictive value of the first-round outcome on the final bout result, and the association between judges' warnings and knockdowns with round and bout outcomes.
Data were collected from the official website of the World Boxing 2025 World Championship in Liverpool. The analysis included 94 male bouts across three weight categories – up to 60 kg, up to 75 kg, and above 90 kg. For each bout, we recorded the round-by-round scoring of all five judges, as well as the occurrence of warnings and knockdowns. Statistical analysis was performed using IBM SPSS Statistics 31. Inter-judge consistency was assessed using the intraclass correlation coefficient (ICC), the influence of the first-round outcome on the final bout result was examined using binary logistic regression, and the association between judging events and outcomes was tested using the χ² test or Fisher's exact test.
Results showed high to excellent inter-judge consistency across all three rounds, with the highest agreement observed in the first round (ICC = 0.982), slightly lower in the second round (ICC = 0.896), and high again in the third round (ICC = 0.913). The first-round outcome proved to be an exceptionally strong predictor of the final bout result across all analyzed categories. Boxers who won the first round had 45.56 times greater odds of winning the bout overall. The presence of a judge's warning was statistically significantly associated with the round outcome in the overall sample (p = 0.001) and in the heavyweight category (p = 0.009), while a knockdown had a decisive impact on the individual round (p < 0.001), but not necessarily on the overall bout result.
The findings indicate that the 10-point must scoring system in Olympic boxing enables a high level of inter-judge consistency. The first round holds key tactical and predictive significance, and tactical discipline directly influences judging outcomes. The results have practical implications for coaches, athletes, and administrators of judging systems in Olympic boxing.
