A new validation paper has been published on the Indian Journal of Physiology and Pharmacology where was shown the test-retest reliability of the K4b2. This study was undertaken to assess test-retest reliability of K4b2 in measuring VO2 and VCO2 during walking, stair climbing and descending stairs in a free living environment. Twelve participants completed two self-selected comfortable paced walking...

Wearable Technologies magazine features an article on the latest breath and respiration analyzing technologies and devices. Among other products, COSMED K5 wearable metabolic technology is introduced as a device that can tell how many calories a professional athlete has burned during the workout.

A new validation on Fitmate reliability during exercise tests was recently published on the Scandinavian Journal of Clinical & Laboratory Investigation. The purpose of this study was to assess the reliability of the FitMate ™ metabolic system and to compare its reliability with the previously studied portable breath-by-breath analyzers Cosmed K4b2. Expired gas, ventilation were recorded in...

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...
