Influence of appendicular skeletal muscle mass on resting metabolic equivalents in patients with cardiovascular disease: Implications for exercise training and prescription

Abstract

The metabolic equivalent (MET) is a widely used physiological concept for quantifying levels of habitual physical activity and cardiorespiratory fitness (CRF) by conveying oxygen consumption requirements of physical activities as multiples of resting or basal metabolic rate (RMR). It may also be used as a means of prescribing workload for exercise training in patient groups, including those attending cardiac rehabilitation (CR). One MET is considered equivalent to the oxygen consumed per kg of body mass at rest (whilst sitting) and, due to practical issues with direct metabolic cart measurement, it is conventionally approximated as 3.5 ml∙kg–1∙min–1. This expression of resting energy expenditure has been incorporated within physical activity position statements and guidelines. However, a number of factors including age, gender, body mass (fat-free mass), cardio metabolic health, and CRF influence RMR, which might limit the broad applicability of the conventional 1 MET at a population level.
