Reliability and Validity of Physical Performance Tests in Individuals With Obesity
Clinician-Friendly Physical Performance Tests in Individuals With Obesity: Reliability and Validity
This study aims to investigate the reliability and validity of practical performance-based physical function tests in individuals with obesity. Functional limitations such as reduced walking ability, impaired balance, and decreased lower extremity strength are common in people with obesity and may negatively affect daily activities and quality of life.
Participants will complete several commonly used clinical functional tests, including the 1-Minute Stair Climbing Test, 40-Meter Fast-Paced Walk Test, 2-Minute Walk Test, Timed Up and Go Test, and 30-Second Sit-to-Stand Test. In addition, cardiopulmonary exercise testing, balance assessment, and knee extensor muscle strength measurements will be performed.
The study will evaluate whether these simple and clinically applicable tests provide reliable results over repeated measurements and whether they are associated with objective indicators of physical function such as maximal oxygen consumption (VO₂max), balance performance, and muscle strength. The findings may help clinicians use practical and cost-effective tools to assess physical function in individuals with obesity.
