This study found significant differences in AOP between males and females in dominant and non-dominant legs, as well as between dominant and non-dominant legs in males. Leg circumference was the most influential predictor of AOP, and there was a linear relationship between blood flow and occlusion pressure.
Background and Objectives: Blood flow restriction during low-load exercise stimulates similar muscle adaptations to those normally observed with higher loads. Differences in the arterial occlusion pressure (AOP) between limbs and between sexes are unclear. We compared the AOP of the superficial femoral artery in the dominant and non-dominant legs, and the relationship between blood flow and occlusion pressure in 35 (16 males, 19 females) young adults. Materials and Methods: Using ultrasound, we measured the AOP of the superficial femoral artery in both legs. Blood flow at occlusion pressures ranging from 0% to 100% of the AOP was measured in the dominant leg. Results: There was a significant difference in the AOP between males and females in the dominant (230 +/- 41 vs. 191 +/- 27 mmHg; p = 0.002) and non-dominant (209 +/- 37 vs. 178 +/- 21 mmHg; p = 0.004) legs, and between the dominant and non-dominant legs in males (230 +/- 41 vs. 209 +/- 37 mmHg; p = 0.009) but not females (191 +/- 27 vs. 178 +/- 21 mmHg; p = 0.053), respectively. Leg circumference was the most influential independent predictor of the AOP. There was a linear relationship between blood flow (expressed as a percentage of unoccluded blood flow) and occlusion pressure (expressed as a percentage of AOP). Conclusions: Arterial occlusion pressure is not always greater in the dominant leg or the larger leg. Practitioners should measure AOP in both limbs to determine if occlusion pressures used during exercise should be limb specific. Occlusion pressures used during blood flow restriction exercise should be chosen carefully.
