This study aimed to evaluate the presence of dynamic hyperinflation (DH) during the Glittre-ADL test (TGlittre) coupled to the dynamic ventilation measurements in people with central obesity (pwCO) and to correlate it with lung mechanics at rest. Sixty-four pwCO underwent TGlittre and the following resting lung function tests: spirometry and impulse oscillometry system (IOS). On TGlittre, 22 participants presented DH at the end of the test (DH group), while 42 did not present DH (NDH group). Body mass index (BMI), waist circumference (WC), and hip circumference (HC) were higher in the DH group than in the NDH group. IOS abnormalities were more common in the DH group compared to the NDH group. TGlittre time significantly correlated with BMI, WC, waist-to-hip ratio (WHR), and neck circumference (NC). Delta inspiratory capacity correlated significantly with WC, HC, NC, and resonance frequency measured by IOS. Thus, pwCO perform worse on TGlittre, and DH is frequent in those with higher anthropometric indices and worse lung mechanics.
