Muscle energetics and the cardiovascular response to isometric exercise and post-exercise circulatory occlusion following exercise-induced muscle damage: insights from multiparametric MRI
Our multi-parametric MRI approach provides new insights into the local effects of muscle damage on energy metabolism, oxygenation, and Na<sup>+</sup>. Despite these local metabolic and microvascular disturbances, systemic cardiovascular responses, as indicated by MAP and HR, remained unchanged. These new findings suggest a dissociation between muscle metabolites, oxygenation, and the cardiovascular response to exercise and PECO 48 h after damaging exercise.
