We analysed differences in myocardial T1 between non-athletic subjects and athletes (which started endurance training early or late in life) to determine inter-center consistency. In addition, we implemented and extended MOLLI scheme (5s5s1s) to improve precision at very low heart rate typical in athlete's and compared with results from a standard 5s3s MOLLI. Absolute levels were dependent on MOLLI scheme and site, but group differences were very similar as evident from full myocardium T1 histograms.
