Association of Breathing Reserve at Peak Exercise With Body Composition and Physical Function in Older Adults With Obesity.

ABSTRACT:

Background

Adiposity-related ventilatory constraints in older adults can potentially contribute to greater risk of exercise intolerance and mobility disability. This study investigated whether ventilatory limitation, measured by breathing reserve (BR) at peak exercise, is associated with body composition and physical function in older adults with obesity.

Methods

This study was a cross-sectional analysis of data from a community-based cohort (N = 177) of older men and women (65-79 years) with obesity (body mass index = 30-45 kg/m2). All participants underwent cardiopulmonary exercise testing on a treadmill, dual-energy X-ray absorptiometry for body composition, and physical function assessments. We examined relationships between BR and body composition and physical function
