Acute effect of static exercise on the cardiovascular system: assessment by cardiovascular magnetic resonance

Purpose The acute effect of static exercise on the global dynamics of the cardiovascular system is poorly understood. The use of cardiovascular magnetic resonance (CMR) may be useful for evaluating this effect. Methods A total of 12 healthy individuals underwent CMR imaging at rest and while perform...

Description
Summary:Purpose The acute effect of static exercise on the global dynamics of the cardiovascular system is poorly understood. The use of cardiovascular magnetic resonance (CMR) may be useful for evaluating this effect. Methods A total of 12 healthy individuals underwent CMR imaging at rest and while performing a maximal sustained static exercise (weight elevation with both legs). We analyzed the effects on left and right ventricular function, ascending aorta dynamics, and venous capacitance using standard cine and phase-contrast sequences. Results We observed excellent reproducibility in the measurements of the images obtained at rest as well as during static exercise. During exercise, we observed reduced left (−35 ± 8 %, p
