Respiratory and Exercise Responses by Body Roundness Index in Obesity
Starting soon
Conditions studied: Obesity
In brief
This observational study aims to evaluate respiratory performance and exercise responses according to Body Roundness Index (BRI) in individuals with obesity. Participants will undergo anthropometric and body composition assessments, respiratory muscle strength testing, pulmonary function evaluation, and a six-minute walk test. Exercise-related ventilatory responses, dyspnea, fatigue perception, oxygen saturation, and heart rate responses will also be assessed. The study seeks to investigate the relationship between BRI and cardiopulmonary performance and to determine whether BRI may serve as a useful indicator of obesity-related functional limitations and exercise capacity.
