Key result
Arm and leg training linked to ~56% steeper peak forearm blood flow response versus leg training.
Why the study?
Whether the immediate rapid vasodilation response to exercise onset can be modified with exercise training was unknown.
Does arm and leg exercise training improve the immediate and peak forearm vasodilatory response to a single forearm contraction compared to leg training alone in male athletes?
Population
17 male varsity athletes (8 distance runners and 9 rowers) from Queen's University
Comparison
Arm and leg trained athletes (rowers) vs leg trained athletes (distance runners)
Design
Cross-sectional study with beat-by-beat vascular measurements during brief forearm contractions

May influence rapid vasodilation onset in trained athletes; leaves open whether training modifies contraction-induced mechanisms.
Cross-Sectional (n=17)
No

Absolute Event Rate: 8.6% vs 5.5%
p-value: p=0.02
Rapid vasodilatory mechanisms responsible for the onset of exercise hyperemia can be improved with local exercise training in young, healthy males.
Matusiak et al. (2010) conducted a cross-sectional in Healthy athletes (n=17). Arm and leg training (rowing) vs. Leg training only (distance running) was evaluated on Slope of the peak forearm blood flow response vs. contraction force (ml/min/kg) (p=0.02). Arm and leg trained athletes (rowers) had a significantly steeper slope of peak forearm blood flow response to contraction force compared to leg trained athletes (8.6 vs. 5.5 ml/min/kg, P=0.02).
