Implication

May support targeted endurance training for vascular reactivity; leaves open causal effects in clinical populations.

Structured PICO

Does long-term intensive training involving predominantly upper or lower limbs improve vascular reactivity and blood flow compared to sedentary controls?

P
Population
31 individuals, comprising 11 cyclists, 10 swimmers, and 10 sedentary controls
I
Intervention
Long-term intensive training involving predominantly either the lower limb (cycling) or upper limb (swimming) musculature
C
Comparator
Sedentary lifestyle (controls)
O
Outcome
Post-occlusion endothelium-dependent flow-mediated dilation (FMD), endothelium-independent glycerine trinitrate-induced dilation (GTND), and exercise-induced blood flow changes in the arm (axillary artery) and leg (superficial femoral artery)surrogate

Long-term intensive training improves endothelial function and vasodilatory capacity in predominantly trained limbs, with lower limb training also enhancing vascular reactivity in upper limb vessels.
