Abstract
Objective: Intake of specific micronutrients can influence blood pressure and reduce related complications such as cardiovascular and renal dysfunction. This study investigated the effect of a multi-element mineral supplement (Cal/Mag/Zinc) combined with aerobic exercise on blood pressure and urinary indices of kidney function in women with hypertension.
Methodology: In this experimental study, 48 middle-aged women with hypertension were randomly assigned to four groups: aerobic exercise (AE), mineral supplement (MCZ), aerobic exercise plus supplement (AE+MCZ), and control. The intervention lasted 8 weeks, with three 45-minute sessions per week at moderate intensity (40–60% HRR), and the daily supplement contained calcium(350 mg), magnesium(175 mg), and zinc(5 mg). Twenty-four-hour urinary proteins (albumin and creatinine) were measured using an autoanalyser.
Results: According to the analysis of covariance, reductions in albumin, albumin-to-creatinine ratio (UACR), systolic, and diastolic blood pressure differed significantly between groups (P<0.05). The post hoc test showed that the AE+MCZ group had a significant reduction in systolic and diastolic blood pressure, albumin, and UACR compared to the other groups, while the AE group showed a significant reduction in systolic and diastolic blood pressure and albumin compared to the control group (P<0.05). Changes in the combination group were greater than those in the training group.
Conclusion: Regular aerobic exercise alone and combined with calcium, magnesium, and zinc supplementation plays a beneficial role in reducing blood pressure while maintaining kidney health, and can be an effective non-pharmacological approach to improving the cardiorenal status of women with hypertension.
