Key result
Lower-limb compression attenuated the exercise-induced increase in skeletal muscle microvascular blood flow, which was offset by increased muscle oxygen extraction.
Why the study?
Due to methodological limitations, changes in muscle microvascular blood flow are rarely assessed in humans during interventions like compression garment use.
Do lower-limb compression tights alter muscle microvascular and femoral artery blood flows following intense exercise in healthy adults?
Do lower-limb compression tights alter muscle microvascular and femoral artery blood flows following intense exercise in healthy adults?
Lower-limb compression attenuates exercise-induced increases in skeletal muscle microvascular blood flow despite increasing femoral artery blood flow, with decreased perfusion offset by increased muscle oxygen extraction.

Should not change exercise compression practice; leaves open compensatory oxygen extraction mechanisms for prospective trials.
Broatch et al. (2021) studied Healthy adults (n=10). Lower-limb compression tights vs. Without compression tights (control) was evaluated on Muscle microvascular blood flow, femoral arterial blood flow, and muscle oxygenation. Lower-limb compression attenuated the exercise-induced increase in skeletal muscle microvascular blood flow, which was offset by increased muscle oxygen extraction.
