SUMMARY:

Introduction: Blood flow restriction (BFR) training is an effective method for promoting muscular adaptations using low loads, with limb occlusion pressure (LOP) being a critical parameter for its individualization. Body composition and body position may influence LOP, but these relationships remain underexplored. Purpose: This study aimed to examine associations between lower-limb body composition and LOP in different body positions and compared these associations between sexes. Methods: Fifty-one healthy adults (25 men, 26 women) participated in this cross-sectional study. LOP was measured in supine, seated, and standing positions using a portable vascular Doppler and an 18 cm cuff. Body composition was assessed via dual-energy X-ray absorptiometry (DEXA), including lower-limb total, lean, and fat mass, as well as body fat percentage. Pearson and Spearman correlations were performed, stratified by sex and position. Results: In the total sample, LOP correlated with lower-limb total mass in supine (r = 0.335; p = 0.016), seated (r = 0.375; p = 0.007), and standing (r = 0.653; p < 0.001) positions. Lean mass correlated with LOP in supine (r = 0.317; p = 0.023) and standing (r = 0.586; p < 0.001), but not seated, while fat mass correlated only in the seated position (r = 0.286; p = 0.042). Among men, LOP was positively associated with lean mass in all positions. Among women, LOP was most strongly associated in the standing position with fat mass (r = 0.571; p = 0.002), total mass (r = 0.513; p = 0.007), and body fat percentage (r = 0.451; p = 0.021). Conclusions: LOP is influenced by body composition, with distinct patterns across sexes and positions. These findings highlight the need to consider body composition and position when prescribing BFR training.
