Abstract Every second of non‐selected men below the age of 55 years who had survived a myocardial infarction was placed in a group for physical training, while each other constituted a control. The physical training program was selected according to each patient's individual maximal working capacity and lasted for 9 months, beginning 3 months after the myocardial infarction. At the end of the training period the experimental group was subdivided into one group of adequately trained patients and one consisting of drop‐outs and patients with poor adherence. The patients who followed the program increased their physical work performance. In this group a decrease was found in plasma insulin values after a glucose tolerance test, a slight increase in glucose tolerance and a decrease in body fat and plasma triglycerides. Body cell mass and plasma cholesterol did not change. The men selected for the training program, but who were not able to follow it sufficiently, as well as the controls, showed a less marked decrease in plasma insulin values at reexamination.
