Body Composition, Functional Capacity, and Respiratory Muscle Endurance in Obesity With Restrictive Ventilatory Pattern

Starting soon

Conditions studied: Obesity

In brief

This observational cross-sectional study aims to examine the relationship between body composition, functional capacity, and respiratory muscle endurance in individuals with obesity and a restrictive ventilatory pattern. A total of 100 adults aged 25-60 years with a body mass index (BMI) ≥30 kg/m² and restrictive pulmonary function findings will be enrolled. Participants will evaluate body composition assessment using bioelectrical impedance analysis, pulmonary function testing by spirometry, respiratory muscle strength and endurance measurements, and functional capacity evaluation using the Six-Minute Walk Test (6MWT). The aim of this study is to evaluate the relationships between stem cell count (SCC), a novel anthropometric indicator called WWI, trunk muscle mass, and functional capacity in obese individuals with a restrictive ventilatory pattern.
