The Breathing IQ: an anthropometric index of diaphragmatic breathing efficiency
Published 2025-04-01“…Respiratory research has consistently called for the standardization of methods that can consider breathing as multifactorial and also consider breathing mechanics.AimThis paper aims to introduce the Breathing IQ (BIQ) as a novel anthropometric index of abdominothoracic flexibility for identifying biomechanical breathing patterns and assessing diaphragmatic breathing efficiency.MethodA sample of N = 384 individuals was assessed with the BIQ pre- and post-intervention of five corrective exercises in a single 90-minute session to identify changes in the BIQ grade (A–F), as determined by measuring the breathing range of motion (ROM) and location of movement (LOM).ResultsBinary-grade improvement (yes/no) occurred in 331 of 370 without an A grade at baseline (89.5%), p < 0.001. …”
