This master's thesis explores the influence of individual segments of the triathlon on athletes' placements in triathlon races at the Olympic Games from 2000 to 2021. Triathlon is becoming an increasingly popular sport, consisting of swimming, cycling, and running. The Olympic Games represent the pinnacle of triathlon competition, where the best athletes from around the world showcase their skills and endurance. The aim of this research is to analyze the impact of each triathlon segment on the athletes' final placements at the Olympic Games. Through an analysis of competition results from 2000 to 2021, the correlation between the times achieved in each segment and the final placements was investigated. The research methodology involved collecting data on athletes' times in each triathlon segment at the Olympic Games during the specified period. The data were analyzed using statistical methods to determine the relationship between results in individual segments and the final placements. The research results are presented in the form of tables based on statistical analyses. Regression analysis identified the greatest impact of the running segment on results for both men and women, while the analysis of variance (ANOVA) showed statistically significant differences in results between men and women in all segments except the first transition. The discussion focused on interpreting the results and drawing conclusions from the research. Possible factors that could influence triathlon results at the Olympic Games, such as course conditions, weather conditions, and athletes' conditioning, were also discussed. Finally, the conclusion summarized the main findings of the research, highlighting the significant influence of the running segment on the final placement. This master's thesis provides insight into the specific aspects of triathlon as an Olympic discipline and assists coaches and athletes in better understanding the key segments of triathlon and their impact on competitive success.
