Abstract Purpose: This study investigated post-Wingate changes in blood gas and acid–base parameters in elite male marathon runners competing at the Olympic level. Associations between these responses and anaerobic performance indicators were also explored. Methods: Elite male marathon runners (n = 28) voluntarily participated in the study. All participants completed a standard Wingate Anaerobic Power Test during a single testing session. Mean power output and fatigue index were recorded as indicators of anaerobic performance. Blood gas and acid–base parameters were measured immediately before the test and at three minutes post-exercise. Pre–post comparisons were analysed using paired-samples t-tests, and correlations between performance indicators and physiological variables were examined using Pearson correlation analysis. Results: Following the Wingate test, statistically significant changes were observed in pH, pO₂, pCO₂, and HCO₃⁻ values (p 0.05). A significant positive correlation was identified between mean power and ΔpO₂ (p 0.05). Ortalama güç ile ΔpO₂ arasında anlamlı pozitif bir korelasyon tespit edilmiş (p < 0.05), diğer değişkenler arasında ise anlamlı bir ilişki bulunmamıştır. Sonuç: Genel olarak bulgular, Wingate testinin elit maraton koşucularında ölçülebilir sistemik asit–baz değişikliklerine yol açtığını; ancak bu fizyolojik yanıtların anaerobik performans göstergeleri ile yalnızca sınırlı düzeyde ilişkili olduğunu göstermektedir. Anahtar Kelimeler Asit–baz dengesi, anaerobik performans, kan gazı analizi, maraton koşucuları, Wingate.
