The K5 is widely recognized as a gold standard device for portable metabolic testing, with multiple peer-reviewed studies supporting its accuracy and reliability. This device provides portability, precision, and flexibility that are not available in other metabolic analysis devices. Unlike traditional, lab-bound metabolic carts, the K5 unit allows for precise, real-time data collection in a variety of environments, including laboratories, field settings, and athletic training facilities. This feature is particularly important for research involving sports performance, outdoor exercise, and environmental physiology. Additionally, The K5 offers breath-by-breath analysis, providing high-resolution data essential for identifying small but significant physiological changes during exercise testing or RMR measurements. The device’s software is compatible with the department’s existing data analysis tools, allowing for efficient data transfer, analysis, and storage. This equipment is needed for us to be comparable to other kinesiology research programs nationally and internationally in methodology for scientific publications.
