Test–Retest Reliability and Minimum Detectable Change Using the K4b2: Oxygen Consumption, Gait Efficiency, and Heart Rate for Healthy Adults During Submaximal Walking

A recent paper, published on "Research Quarterly for Exercise & Sport" furthermore validate COSMED K4b2 portable metabolic monitoring device during submaximal Gait walking.

The purpose of this study was to determine the test–retest reliability and minimum detectable change (MDC) for VO2, Gait Efficiency, and HR with the K4b2 at submaximal walking speeds in healthy young adults.

Twenty-two participants completed 2 identical treadmill tests on separate days at submaximal walking speeds from 0.71 m/s to 1.65 m/s..

The current study is the first to identify the reliability and measurement error for several common physiological parameters (VO2, GE, and HR) collected using the COSMED K4b2 during submaximal walking in healthy adults.
