Table 2. Blood pressure at pre- and post-exercise points with beetroot (BR) and placebo (PL) supplementation in 35 subjects.
| Blood pressure (mmHg) |
BR | PL | Effect size (Cohen's D) |
|---|---|---|---|
| Pre-systolic BP | 111.7 ± 7.7 | 111.4 ± 6.8 | 0.047 |
| Pre-diastolic BP | 70.8 ± 8.7 | 70.1 ± 7.8 | 0.087 |
| Pre-MAP | 84.4 ± 7.8 | 83.8 ± 6.8 | 0.087 |
| Post-systolic BP | 140.3 ± 12.9 | 137.3 ± 15.1 | 0.265 |
| Post-diastolic BP | 67.2 ± 10.2* | 64.5 ± 7.9 | 0.369 |
