Abstrakt: Background Dietary antioxidant Capacity (DaC) has been used as a tool for predicting plasma and dietary antioxidant concentrations. However, the DaC association with oxidative stress (OS) and body composition parameters is an unexplored area, mainly in physically active individuals. Given the potential for increased OS in physically active individuals, it becomes crucial to investigate this association. The aim of this study was to analyze the association between DaC, OS biomarkers, and body composition in healthy and physically active individuals. Methods This Cross-sectional study included 20 male soccer referees. Body composition measurements (body mass, fat mass, lean mass, and waist circumference), OS biomarkers (F2-isoprostane, total antioxidant state, total oxidative status, reduced glutathione, oxidized glutathione, superoxide dismutase, glutathione peroxidase (GPx) and catalase), and DaC were evaluated. Linear regression models were used to determine the association between DaC and the dependent variables. The study was approved by the Human Research Ethics Committee of the Federal University of Santa Catarina (UFSC), CAAE 82584318.0.0000.0121, and file no. 2.572.301. Results DaC was inversely associated with F2-isoprostane (p = 0.044), GPx activity (p = 0.048), and body fat percentage (p = 0.025). Conclusions Increased DaC in physically active individuals may bring benefits related to biomarkers of OS, such as decreasing F2-isoprostane and increasing GPx activity. The increase in DaC also showed an improvement in body composition, demonstrated by the lower percentage of body fat in the study subjects.
