Microcirculatory parameters of triathletes before (baseline) and 20 days after OGJ intake (n = 10).
| Microcirculatory parameters | Baseline | After grape juice intake |
| Functional capillary density (n/mm2) | 10.7±2.3 | 14.9±2.7 * |
| Afferent diameter (µm) | 17.6±2.9 | 17.9±2.0 |
| Apical diameter (µm) | 23.7± 4.1 | 23.7±1.4 |
| Efferent diameter (µm) | 19.8±4.7 | 20.9±3.3 |
| RBCV (mm/s) | 0.3±0.05 | 0.3±0.01 |
| RBCVmax (mm/s) | 0.3±0.02 | 0.4±0.01* |
| TRBCV max (mm/s) | 5.9±2.8 | 4.0±1.1 * |
* p≤0.05 by paired t-test. FCD: functional capillary density; RBCV: red blood cell flux velocity at rest; RBCVmax: red blood cell flux velocity after 1-min arterial occlusion; TRBCVmax: time required to reach peak red blood cell velocity.
