Effect of arm‐cranking on leg blood flow and noradrenaline spillover during leg exercise in man
Why the study?
Does the addition of arm cranking to leg cycling alter leg blood flow and noradrenaline spillover in healthy young men?
Population
7 healthy young men
Comparison
Addition of arm cranking to leg cycling vs Leg cycling alone (work load 55-60% VO2max)

Implication
Provides mechanistic insight into combined-limb exercise hemodynamics; leaves open translation to patients with cardiovascular disease.
Structured PICO
Does the addition of arm cranking to leg cycling alter leg blood flow and noradrenaline spillover in healthy young men?
P
Population
7 healthy young men
I
Intervention
Addition of arm cranking to leg cycling (total work load 82 +/- 4% of VO2max)
C
Comparator
Leg cycling alone (work load 55-60% VO2max)
O
Outcome
Leg blood flow, mean arterial blood pressure, leg vascular conductance, and leg noradrenaline spilloversurrogate
Adding arm exercise to leg exercise increases sympathetic vasoconstriction in the legs, but leg blood flow is maintained by a simultaneous increase in arterial blood pressure.
