Summary

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.

Physical Performance Tests

Participants will undergo a series of standardized performance-based physical function assessments, 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. Each test will be performed twice with standardized rest intervals between assessments. To evaluate test-retest reliability, the same functional tests will be repeated 5-7 days later under identical conditions and in the same order. In addition to functional testing, participants will complete cardiopulmonary exercise testing (CPET) using the Modified Bruce Protocol to determine maximal oxygen consumption (VO₂max), computerized static and dynamic balance assessments using the PROKIN® system, and knee extensor muscle strength measurements using a hand-held dynamometer. No therapeutic intervention or treatment will be administered during the study.
