The heart is a unique muscle whose health and aerobic capacity (VO2 max) can be improved through specific physiological interventions.

Andy Galpin emphasizes cardiac plasticity here, a well-established concept in exercise physiology. Research largely confirms that the heart adapts to training, notably through an increase in stroke volume and better mitochondrial efficiency (meta-analyses on aerobic training, e.g., American Heart Association). VO2 max is recognized as one of the most robust indicators of longevity and cardiovascular health (prospective observational studies). The statement that the heart is a "unique" muscle is scientifically accurate regarding its structure (involuntary striated muscle) and its electrophysiological properties. There is no exaggeration here, as Galpin focuses on documented mechanisms of cardiac adaptation. Advice aimed at improving these parameters through exercise is supported by a solid scientific consensus.
