Abstract
| Background: Blood group variations may influence athletic performance, yet their distribution and competitive implications among university athletes remain underexplored within sustainable athletic development frameworks. Objective of the study is to characterize blood group distribution and assess its association with winning status in university athletes. Methods: A cross-sectional study of 210 university athletes (64.3% male; 36.7% professional-level) categorized by sport specialization and ABO/Rh blood typing. Competitive outcomes were tracked during university-level championships. Chi-square tests, standardized residuals, and odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate blood group–winning correlations. Results: Blood group distribution revealed O+ (26.7%), A+ (21.0%), and B+ (18.6%) predominance. A significant association existed between blood groups and winning (χ² = 20.76, p = 0.004; Cramer’s V = 0.31). AB+ (OR=2.27, 95% CI: 0.88–5.82) and B+ (OR=1.73, 95% CI: 0.76–3.94) athletes demonstrated the highest winning odds versus O+ references, with significant positive standardized residuals (AB+: +1.89; B+: +1.62). Rh+ athletes had 3.2× higher winning odds than Rh- counterparts (95% 1.45–7.09, p=0.003). Conclusion: AB+ and B+ blood groups correlate with superior competitive outcomes, while Rh+ status confers a significant winning advantage. These findings highlight haematological factors as potential biomarkers for talent identification and sustainable athlete health optimization.
