The effect of anthocyanin supplementation on systolic and diastolic blood pressure and mean arterial pressure in athletes

Introduction: Anthocyanin has cardio-protective roles, and anti-inflammatory effects. Exercise can play effective roles in this area. We assessed the effects of anthocyanin supplements on blood pressure and mean arterial pressure in combination with exercise. 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. Data analyzed using analysis of covariance (ANCOVA) test by using SPSS software (version 21.0). Pvalue<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. Conclusion: Anthocyanin supplements did not affect SBP, DBP and MAP after performing treadmill exercises in non-professional athletes, significantly. Exercise causes a significant increase in MAP values, while this enhancing did not show a significant difference between two groups.
