Abstract

The purpose of this study was to examine the effects three cuff widths (5 cm, 10 cm, 12 cm) have on arterial occlusion pressure (AOP) in the arm. A secondary purpose was to determine if arm circumference, blood pressure, arm length, and sex should be accounted for when applying these cuff widths. Two hundred and forty-nine participants visited the laboratory one time to measure arm length, arm circumference, brachial systolic (bSBP) and diastolic blood pressure (bDBP) followed by assessment of standing AOP as determined by a Doppler probe. One way repeated measure ANOVAs were used to examine differences between cuff widths and sex. Hierarchical linear regression was used to determine the variables explaining the most unique variance for each cuff width. Significant differences were observed between all cuff widths (p < 0.001) with AOP being highest for the 5 cm cuff [145 (19) mmHg] then 10 cm cuff [123 (13) mmHg], and 12 cm cuff [120 (12) mmHg]. Although a model consisting of arm circumference, bSBP, arm length, bDBP, and sex explained the most variance in AOP for all three cuffs (5 cm, R2 = 0.651; 10 cm, R2 = 0.570; 12 cm, R2 = 0.557), arm circumference explained the most unique variance for each cuff width (5 cm, Part = .554; 10 cm, Part = .419; 12 cm, Part = .406). There were significant sex differences in AOP for the 5 cm [males 149 (19); females 142 (19) mmHg, p = 0.003, d = 0.36], 10 cm [males 127 (13); females 121 (13) mmHg, p = 0.002, d = 0.46], and 12 cm [males 122 (12); females 118 (12) mmHg, p = 0.009, d = 0.33] cuffs. Wider cuffs, in comparison to narrow cuffs require less pressure for AOP in the arm while standing. Future studies should report the cuff width used and carefully consider the impact it has on the amount of restriction occurring. Since AOP is affected by individual differences, the same pressure should not be applied to all participants. In order to make BFR relative in the upper body, arm circumference and bSBP should be accounted for.
