Changes in microcirculatory parameters in marathon runners during the study period.
| Visit I | Visit II | Visit III | Visit IV | ANOVA, p | |
|---|---|---|---|---|---|
| MFI | 2.83 ± 0.15 | 2.92 ± 0.16 | 2.93 ± 0.12 | 2.89 ± 0.10 | 0.704 |
| PPV (%) | 94.4 ± 3.8 | 96.6 ± 2.0 | 96.7 ± 3.7 | 95.0 ± 3.6 | 0.409 |
| FCD (mm/mm2) | 19.0 ± 4.7∗ | 19.5 ± 4.1∗ | 18.6 ± 3.8∗ | 19.1 ± 4.3∗ | 0.976 |
| TVD (mm/mm2) | 20.1 ± 5.0∗ | 19.8 ± 5.3∗ | 19.8 ± 4.9∗ | 20.5 ± 5.1∗ | 0.989 |
Data are presented as mean ± SD. MFI: microvascular flow index of small vessels; PPV: percentage of perfused small vessels; TVD: total vessel density of small vessels; FCD: functional capillary density. Visit I, 24 hours before the marathon; Visit II, right after finishing the marathon; Visit III, 24 hours after the marathon; Visit IV, one week after the marathon. ∗p < 0.05 compared with controls.
