Background: cardiometabolic disorders in several kinds of fruits, vegetables, and herbal sources. In this study, we assessed the effects of anthocyanin supplements on systolic and diastolic blood pressure values and mean arterial pressure in athletes. Materials and methods This randomized double-blind clinical trial conducted on 54 athletes. Participants in intervention group were taken 100 mg anthocyanin supplements, daily for 6 weeks and control group received similar placebo. Systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were determined before and after performing treadmill test. Dietary intake and physical activity of subjects had been assessed at baseline and after intervention period. Data analyzed using analysis of covariance (ANCOVA) test by using SPSS software (version 21.0). Pvalue lower than 0.05 was set as significant level. Results SBP is similar between two groups before intervention while its mean value increased after performing treadmill test. SBP and DBP increase was not affected by taking treatments after exercise.SBP increase was higher in placebo group in compare to anthocyanin group, after exercising. MAP was not different before and after taking pills, significantly. Anthocyanin supplements did not affect SBP, DBP and MAP values after performing treadmill exercises in non-professional athletes, significantly. Conclusion Data shows that performing the mentioned exercise causes a significant increase in MAP values in both groups, while this enhancing did not show a statistically significant difference between intervention and control groups.Background and aim cardiometabolic disorders in several kinds of fruits, vegetables, and herbal sources.
