Cardiac structure and systolic function in resistance-trained athletes versus untrained male adults

Both structural and functional differences in cardiac measures are apparent when comparing those engaged in chronic resistance-trained to untrained individuals. Furthermore, despite these structural differences, no significant impairment in left ventricular function was observed. However, whilst the cardiac dimensions of most resistance-trained athletes do not exceed the upper limits for physiological hypertrophy the exact mechanism for these differences is unclear and warrants further investigation.
