Abstract

Objective: This study aimed to investigate whether obese men and women experience changes in IME and functional capacity. Methods: Ten obese women, 10 normal-weight women, 9 obese men, and 10 normal-weight men underwent assessments of inspiratory muscle strength using maximal inspiratory pressure (MIP), IME through an inspiratory load, and functional capacity using the 6-Minute Walk Test (6MWT). Results: IME was lower in obese men and negatively associated with BMI and waist circumference. Among obese women, the distance covered in the 6MWT was shorter than that of normal-weight women and was negatively correlated with BMI and waist circumference. Final Considerations: Obese men have reduced IME, while obese women demonstrate lower functional capacity. Both findings are associated with larger waist circumference and higher BMI. Furthermore, waist circumference is an independent predictor of IME in men and functional capacity in women.
