Physical fitness affects metabolic rate through multiple mechanisms: lean mass accretion, mitochondrial adaptations, and improved insulin sensitivity. This article reviews the evidence on how different fitness components interact with metabolic function.

Different types of exercise have distinct effects on metabolic rate through EPOC, lean mass accretion, and NEAT changes. This article reviews the evidence on resistance training, HIIT, aerobic exercise, and NEAT for metabolic rate, with quantified effect sizes.
