Key result
Four weeks of inorganic nitrate supplementation attenuated retrograde and oscillatory shear in the brachial artery of older adults, without improving hyperemic or vasodilatory responses to exercise.
Why the study?
Does inorganic nitrate supplementation reduce retrograde and oscillatory shear in the brachial artery in older adults?
Does inorganic nitrate supplementation reduce retrograde and oscillatory shear in the brachial artery in older adults?
Inorganic nitrate supplementation for 4 weeks improves brachial artery shear patterns in older adults, which may reduce the risk of atherosclerotic cardiovascular disease, despite no improvement in exercise-induced vasodilation.
No takes yet. Share an insight, caveat, or question.
Nitrate supplementation improves shear patterns in older adults without enhancing exercise hyperemia; extends mechanistic evidence for vascular benefits in aging.
Casey et al. (2021) studied Older adults. Inorganic nitrate supplementation was evaluated on Retrograde and oscillatory shear in the brachial artery. Four weeks of inorganic nitrate supplementation attenuated retrograde and oscillatory shear in the brachial artery of older adults, without improving hyperemic or vasodilatory responses to exercise.
