Long-term military training leads to the remodeling of the heart and may cause exercise-induced myocardial injury (EIMI). The mechanism of heart remodeling is studied by using cardiac cine MRI to estimate left ventricular cardiac function and global stress. This study found that prolonged and intensive training lasting 4 years leads to cardiac morphological adaptations. Contrary to conventional thinking, left ventricular function changes happens earlier than the mechanical direction.
