The primary objective of this study is to investigate the effect of short-term bed rest (4 hours) on heart function, measured by cardiac magnetic resonance (CMR), in healthy participants. This aim will be addressed through a single-arm repeated study, assessing participants during three hours of bedrest. The hypothesis is that short-term bed rest will decrease cardiac output measured by repeated CMR scans. This study will also investigate the reproducibility of CMR within a narrow time frame. Limited data are available on these aspects, despite their critical importance for conducting consecutive examinations, both in clinical practice and research trials10-12. The study also aims to investigate the appliances of short-time measures of cardiac function.
