12 Σεπ 2000 · This exercise intervention caused a substantial increase in arterial compliance, thereby partially reversing the age-related changes. What mechanisms might explain the reduced arterial compliance with aging, and how are they modified by exercise?
Regular aerobic exercise has been recognized as an effective preventive strategy to reduce central arterial stiffness ; in addition, both moderate continuous exercise (MCE; 35% HRR) and interval exercise (IE; 35% HRR) may temporarily improve the degree of arterial stiffness in humans.
26 Δεκ 2019 · Figure 1. Top, the typical nonlinear relation between luminal pressure and area in large elastic arteries, explained by the progressive shift in load bearing from elastin to collagen fibers. Data translate into distensibility and pulse wave velocity (PWV) with the use of the Bramwell-Hill relation.
the elastic properties, particularly of large arteries, are impaired in the presence of cardiovascular disease and risk factors such as cigarette smoking, hypertension, diabetes and ageing. Evidence is also emerging that treatment of these risk factors
Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries.
Key points. 1 An eficient. cardiovascular system is essential for health and longevity, but age brings about changes that reduce its eficiency. 2 Blood particularly vessels, arteries, lose their elasticity with age, and the arterial walls become stifer and thicker.
Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries. The pulmonary arteries, the aorta, and its branches together comprise the body’s system of elastic arteries.
