What was done
This narrative review synthesized current literature regarding the molecular and clinical vascular adaptations to acute and chronic exercise. It evaluated how exercise prescription variables—frequency, intensity, time/volume, and type (F-I-T-T)—affect vascular structure and function across healthy individuals and cardiovascular disease patients.
What was found
The abstract reports no numerical data or quantitative effect estimates. It summarizes that exercise increases vascular wall shear stress, stimulates endothelial growth factors, and triggers exerkine release, leading to improved vasomotor responsiveness, reduced arterial stiffness, enhanced angiogenesis and arteriogenesis, and reduced oxidative stress. The authors note that cumulative shear stress volume may be more important than peak shear stress, frequent exercise (5–7 days per week) optimizes benefits, and combined aerobic and resistance training across intensities is advantageous across all age groups.
Why it matters
The paper outlines how mechanical and molecular exercise stimuli drive vascular adaptation, providing a conceptual framework for prescribing individualized exercise across the lifespan to prevent early vascular aging.
Limits
As a narrative review, it lacks a systematic search protocol, quality assessment of included studies, and quantitative data synthesis. Specific evidence defining optimal F-I-T-T parameters remains limited, precluding exact training recommendations based on the abstract.
