Why the study?
To investigate how high-intensity exercise influences myocardial resilience and its correlation with markers of myocardial ischemic injury.
Does high-intensity exercise induce changes in myocardial strain that correlate with markers of myocardial injury in swimmers?
Comparison
Before vs after high-intensity exercise
Follow-up
6 hours after exercise

Small observational study in athletes leaves open exercise effects on myocardial strain and ischemic correlations; larger prospective trials needed.
Does high-intensity exercise induce changes in myocardial strain that correlate with markers of myocardial injury in swimmers?
Two-dimensional ultrasound deformation indices correlate with cardiac enzyme release after high-intensity exercise, suggesting utility as a non-invasive diagnostic tool for exercise-induced myocardial injury.
Gao et al. (2021) studied this question.
