Kutztown University (KU) requests the sole source purchase of the COSMED K5 Wearable Metabolic Technology which is only available from the manufacturer. The K5 is a breakthrough metabolic measurement system designed for measuring gas exchange (oxygen consumption and carbon dioxide production) during exercise and at rest. This data is crucial for research in various fields, including exercise science, nutrition, and physiology, to assess metabolism, fitness, and energy expenditure. The COSMED K5 wearable design and unique characteristics allow to expand the scope of metabolic testing outside the traditional boundaries of clinical exercise testing and sport performance assessment with new ways to measure physiological response during exercise in laboratory and in the field without limitations. The K5 utilizes advanced technology to ensure the highest level of accuracy and reliability in metabolic measurements. This is critical for university research, as precise data is essential for drawing accurate conclusions. A study was conducted to determine the reliability and validity of the K5 portable metabolic system and the results confirm the level of accuracy and reliability that is required for the research Kutztown students are conducting. Attached is the study information. This results in a unique and unsurpassed combination of measurement accuracy and data collection versatility that makes the COSMED K5 wearable metabolic technology the most comprehensive wearable metabolic system.
