Effects of regular exercise on blood rheology

Abstract Regular physical activity (RPA) promotes cardiovascular health but its effects on blood flow and rheology characteristics remain unclear. This study compared hemorheological parameters between healthy adults who regularly jogged (n = 35) and sedentary controls (n = 35). Participants in the...

Description
Summary:Abstract Regular physical activity (RPA) promotes cardiovascular health but its effects on blood flow and rheology characteristics remain unclear. This study compared hemorheological parameters between healthy adults who regularly jogged (n = 35) and sedentary controls (n = 35). Participants in the RPA group showed significantly lower fibrinogen levels, C-reactive protein concentrations, blood viscosity, plasma viscosity, and red blood cell aggregation (all p < 0.05). They also had higher hematocrit and albumin concentrations. Blood viscosity decreased by around 30% (native) and 49% (hematocrit-adjusted) in active individuals. These findings suggest regular jogging improves blood flow, potentially protecting against cardiovascular diseases.
