Key result
A single bout of cycling exercise increased signal-averaged sympathetic neurovascular transduction by ~75% in young healthy normotensive adults.
Why the study?
Leg vascular conductance increases after cycling exercise despite unchanged sympathetic nerve traffic in young healthy adults, suggesting discordant responses may reflect modulation in vasoconstrictor responsiveness.
Does a single bout of cycling exercise alter sympathetic neurovascular transduction in young healthy normotensive adults?
Does a single bout of cycling exercise alter sympathetic neurovascular transduction in young healthy normotensive adults?
A single bout of cycling exercise significantly increases sympathetic neurovascular transduction in young healthy adults, which may occur independent of changes in resting vascular conductance.

Should not change practice; leaves open whether enhanced transduction contributes to post-exercise cardiovascular benefits.
Following cycling exercise, leg vascular conductance increases, whereas sympathetic nerve traffic is unchanged in young healthy adults. Discordant vascular and sympathetic responses may reflect modulation in vasoconstrictor responsiveness. The current study demonstrated that signal-averaged sympathetic neurovascular transduction was increased by ∼75% following a single bout of cycling exercise. Secondary experiments using local heating suggest that potentiation in sympathetic neurovascular transduction after exercise may occur independent of changes in resting vascular conductance.

Nardone et al. (2025) studied normotensive adults. Single bout of cycling exercise vs. Baseline/resting state was evaluated on Signal-averaged sympathetic neurovascular transduction (increased by ~75%). A single bout of cycling exercise increased signal-averaged sympathetic neurovascular transduction by ~75% in young healthy normotensive adults.
