Key result
Higher aerobic capacity is linked to reduced arterial stiffness across the adult lifespan.
Why the study?
The effects of age and aerobic capacity on arterial stiffness in healthy normotensive adults aged 20 to 90 years were examined.
Does higher aerobic capacity reduce age-associated arterial stiffness in healthy adults?
Observational
Does higher aerobic capacity reduce age-associated arterial stiffness in healthy adults?
Higher aerobic capacity is associated with reduced arterial stiffness, suggesting that physical conditioning may mitigate age-related vascular stiffening.
Even in normotensive, rigorously screened volunteers in whom SBP increased an average of only 14% between ages 20 and 90 years, major age-associated increases of arterial stiffness occur. Higher physical conditioning status, indexed by VO2max, was associated with reduced arterial stiffness, both within this predominantly sedentary population and in endurance trained older men relative to their less active age peers. These findings suggest that interventions to improve aerobic capacity may mitigate the stiffening of the arterial tree that accompanies normative aging.

Vaitkevicius et al. (1993) conducted an observational in Normative aging and arterial stiffness in healthy normotensive adults. Age and higher aerobic capacity (VO2max / endurance training) vs. Younger age / less active or sedentary age peers was evaluated on Arterial stiffness. Higher aerobic capacity (VO2max) was associated with reduced arterial stiffness across ages 20-90 years, alongside a 14% average SBP increase with age.
