Comparison of two portable metabolic systems for measuring energy expenditure at rest and during exercise in untrained women

Comparison of two portable metabolic systems for measuring energy expenditure at rest and during exercise in untrained women

PurposePortable metabolic systems are used as the “gold standard” for measuring energy expenditure (EE) in the development and validation of wearable devices. This study aimed to compare EE measurements obtained using the COSMED K5 (K5) and CORTEX METAMAX 3B (M3B) during the resting state and submax...
