Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main focus of the project is to determine to what degree myocardial energy metabolism is linked to impaired function in human cardiomyocytes, whether exercise training and remote ischemic preconditioning can restore cardiomyocyte function and whether this is linked to improved mitochondrial and cell function.
