SUMMARY:

Aim

Arterial occlusion pressure (AOP) is a relevant measurement for individualized prescription of exercise with blood flow restriction (BFRE). Therefore, it is important to consider factors that may influence this measure. This study aimed to compare AOP measured with 12 cm (medium) and 18 cm (large) cuffs, in different body positions, and explore the predictors for each of the AOP measurements performed. This information may be useful for future studies that seek to develop approaches to improve the standardization of pressure adopted in BFRE, including proposals for equations to estimate AOP.

Methods

Fifty-one healthy volunteers (males, n = 25, females, n = 26; Age: 18 to 40 years old) underwent measurement of thigh circumference (TC), brachial blood pressure, followed by assessments of lower limb AOP with medium and large cuffs in positions supine, sitting and standing positions.

Results:

The large cuff required less external pressure (mmHg) to elicit arterial occlusion in all three-body positions when compared to the medium cuff. The AOP was significantly lower in the supine position, regardless of the cuff used (p<0.05). Systolic blood pressure was the main predictor of AOP determined with the large cuff, while TC was the main predictor of AOP determined with the medium cuff. Body position influenced the strength of the AOP predictors.

Conclusion

Our results indicate that AOP and its predictors are substantially influenced by body position and cuff width. Therefore, these variables should be considered when standardizing the pressure prescribed in BFRE.
