Scientists from the University of Pisa found that regular physical activity improved blood microcirculation and reduced oxidative stress in people aged 47 to 74 years. The research was published in the journal Scientific Reports.
The study included 36 distance runners aged 47 to 74 and a similar number of healthy, sedentary controls aged 46 to 77. They all had approximately the same body mass index; This was an indicator to assess whether they were overweight. Participants also did not have cardiovascular disease.
The results show that although skin microcirculation was similar at rest in both groups, it was significantly better in active participants under stress. Additionally, plasma concentrations of nitric oxide NO were higher in active participants. Previous studies have shown that this substance supports vascular health and lowers blood pressure.
The antioxidant capacity of the plasma was significantly higher in the active group, meaning their cells were better protected against oxidative stress (damage from reactive oxygen species). Analysis of gene activity and blood biomarkers confirmed this.
The results prove that regular exercise can prevent the aging of vascular endothelial cells. Atherosclerosis and endothelial dysfunction are the most important signs of vascular aging, which increases the risk of stroke, heart attack and other diseases.
