Why the study?
The relationship between cardiac magnetic resonance-derived T1 and T2 mapping and physical fitness is not fully understood, with conflicting literature results.
Does cardiorespiratory fitness correlate with myocardial tissue characteristics assessed by CMR T1 and T2 mapping in elite athletes?
Does cardiorespiratory fitness correlate with myocardial tissue characteristics assessed by CMR T1 and T2 mapping in elite athletes?
In elite athletes, greater cardiopulmonary fitness is associated with larger cardiac volumes and lower myocardial T1 and T2 mapping values, suggesting a link between aerobic adaptation and tissue-level myocardial properties.
Hypothesis-generating for fitness effects on athlete myocardium; should not yet alter CMR interpretation or screening.
