Anthropometric Characteristics and Body Composition Changes in a Five-Time Olympic Champion in Greco-Roman Wrestling: A Longitudinal Case Study Towards the Paris 2024 Olympic Games

<b>Purpose</b>: This case study examines the anthropometric characteristics and body composition changes of a 41-year-old Cuban Greco-Roman 130 kg wrestler, a five-time Olympic gold medalist (2008-2024). To optimize his preparation for the Paris 2024 Olympic Games, another athlete participated in the qualifying process, allowing him to train without competition gear. <b>Methods</b>: The study monitored changes in body composition using anthropometry and bioelectrical impedance analysis (BIA) at three key time points in 2024: January, June, and July. The final assessment occurred 25 days before the Olympic event, coinciding with the final phase of his preparation. <b>Results</b>: The analysis revealed a significant reduction in total body mass, from 150 kg in January to 138.5 kg in July, with fat mass decreasing from 37.06 kg (24.11%) to 29.7 kg (21.5%). Muscle mass decreased slightly (77.41 kg to 72.3 kg), while bone mass remained stable. The somatotype classification was endomorphic-mesomorphic at all assessments, with slight shifts in its components (4.6-10.4-0.1 in January to 4.4-10.3-0.1 in July), reflecting an improved muscle-fat ratio. Notably, hydration levels and cellular integrity remained stable, as indicated by BIVA analysis. <b>Conclusions</b>: This study provides insight into the anthropometric characteristics and body composition of an elite Greco-Roman wrestler, as well as the changes observed during his preparation for his final Olympic participation. These data serve as a valuable reference for wrestlers and sports professionals, highlighting the physical profile of one of the most emblematic figures in Olympic history.
