Key result
A 3-month supervised exercise training program significantly increased maximal calf muscle blood flow and oxygen extraction during treadmill exercise compared to control (P<0.004).
Why the study?
Does 3 months of supervised exercise training improve calf muscle blood flow and oxygen extraction in patients with peripheral artery disease and claudication?
Population
64 patients with peripheral artery disease (PAD) who experience claudication
Comparison
3 months of supervised exercise training vs Control group

Does 3 months of supervised exercise training improve calf muscle blood flow and oxygen extraction in patients with peripheral artery disease and claudication?
p-value: p=<0.004
A 3-month supervised exercise training program enhances muscle oxidative metabolism and microvascular blood flow during physical activity, providing a physiological mechanism for improved walking time in PAD patients.
Baker et al. (2017) conducted an RCT in Peripheral artery disease (PAD) with claudication (n=64). Supervised exercise training vs. Control group was evaluated on Maximal calf muscle blood flow and oxygen extraction levels during treadmill exercise (p=<0.004). A 3-month supervised exercise training program significantly increased maximal calf muscle blood flow and oxygen extraction during treadmill exercise compared to control (P<0.004).
