Agreement of four metabolic equations for estimating submaximal cycling oxygen uptake with two portable indirect calorimetry systems in untrained young women
Metabolic prediction equations provide a low-cost means of estimating submaximal cycling oxygen uptake (VO₂), yet equations derived from maximal exercise are often applied to steady-state fixed-load protocols without validation. Portable analysers including the COSMED K5 and CORTEX MetaMax 3B permit field-based V...
