Abstract

High-intensity exercise can increase oxygen consumption. Beetroot contains phytochemicals that are biologically active substances able to improve post-exercise conditions. Beetroot can be processed into powder. This study aimed to determine the effect of beetroot powder on the improvement of blood pressure and blood glucose level in Wistar rats that received high-intensity exercise. The thirty Wistar rats were randomly divided into 5 groups (n = 6), they controlled negative (G1); control positive (G2); received exercise and 0.36 g/200 g b.wt/day of beetroot powder (G3); received exercise and 0.72 g/200 g b.wt/day of beetroot powder (G4) and received exercise and 1.08 g/200 g b.wt/day of beetroot powder (G5). The treatment was given once a day after exercise for 28 days. The blood pressure was measured using the S-2 sphygmomanometer while blood glucose levels were measured using the GOD-PAP method by taking retroorbital vein blood. The data were analyzed using paired sample t-test and one-way analysis of variance (ANOVA). The results obtained were differences in blood pressure and blood glucose levels before and after the administration of beetroot powder as much as 0.36 g/200 g b.wt/day; 0.72 g/200 g b.wt/day and 1.08 g/200 g b.wt/day in Wistar rats when receiving high-intensity exercise (p<0.005). G4 has the most decrease in systolic blood pressure. G5 showed the lowest increase in blood glucose levels compared to all other groups. Beetroot powder was effective in improving blood pressure and blood glucose levels in Wistar rats who received high-intensity exercise.
