The value of vigorous exercise and the optimal volume of exercise are currently popular topics. In a small Dutch study, MARC-1, healthy, middle-aged, male amateur athletes underwent computed tomography imaging to detect subclinical coronary atherosclerosis. The investigators found that participants with high levels of exercise had more coronary calcium but more-benign composition of plaques. The current follow-up study, MARC-2, assessed the longitudinal relationship between exercise training characteristics and coronary atherosclerosis progression in 289 (92%) of the participants from MARC-1.
During a mean follow-up of 6.3 years, exercise volume (metabolic equivalent of task [MET] hours/week) was not associated with progression in coronary a…
