<![CDATA[Background: Football athletes require good physical fitness to improve their performance. Aerobic endurance, commonly known as VO2 Max, is one of the components of physical fitness. Several factors can affect VO2 Max, including blood glucose and carbohydrate intake.Objectives: To identify the correlation between carbohydrate intake and blood glucose level on VO2 Max in non-elite football athletes at the Universitas Negeri Surabaya Football Club.Methods: The research method was quantitative, with a correlational and cross-sectional research design, which was held in March 2023. The study subjects were 34 athletes from the Universitas Negeri Surabaya Football Club. The instruments used to collect carbohydrate intake data were the SQ-FFQ form, blood glucose data collected by the Easy Touch GCU meter, and VO2 Max data collected by the MFT test. The data analysis in this study used Pearson's Product Moment correlation and Partial Correlation test at a significance level of 95% CI.Results: There was a significant correlation of carbohydrate intake on VO2 Max (p = 0,000 and r = 0,636), and there was a significant correlation of blood glucose on VO2 Max (p = 0,000 and r = 0,670). In addition, there was a significant correlation between carbohydrate intake and VO2 Max with blood glucose as a control variable (p = 0,000 and r = 0,634).Conclusion: There was a significant correlation with a positive correlation of carbohydrate intake and blood glucose on VO2 Max in non-elite athletes of Universitas Negeri Surabaya football club. The higher the carbohydrate intake and blood glucose level, the higher the VO2 Max level. ]]>
