Key result
Higher physical activity quantity was associated with significantly lower central artery stiffness, measured by AIx@75 (-8% vs 6%, p=0.016), in healthy young women compared to lower physical activity.
Why the study?
Arterial stiffness is linked to cardiovascular events and mortality, and regular physical activity reduces it, but the relationship between objectively measured physical activity levels and central artery stiffness needed evaluation in young female adults.
Does higher physical activity level improve central artery stiffness in young female adults?

Does higher physical activity level improve central artery stiffness in young female adults?
Absolute Event Rate: -8% vs 6%
p-value: p=0.016
Augmented physical activity level, including light and moderate-to-vigorous intensity, is associated with reduced central artery stiffness in healthy young women.
Lee et al. (2019) conducted a cross-sectional in Healthy (n=26). Higher physical activity quantity vs. Lower physical activity quantity was evaluated on Augmentation index adjusted at 75 beats per minute (AIx@75) (p=0.016). Higher physical activity quantity was associated with significantly lower central artery stiffness, measured by AIx@75 (-8% vs 6%, p=0.016), in healthy young women compared to lower physical activity.
