MFI					0.704
PPV (%)					0.409
FCD (mm/mm^2)					0.976

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. compared with controls.
