 The present two studies were aimed to investigate safety of weight training in the recovery phase of patients with myocardial infarction.

 Study 1 assessed hemodynamic responses during muscle strengthening exercise for the knee extensors in the recovery phase of 15 patients with myocardial infarction. At every load level, i. e., 40%, 60%, 80% of the 1 repetition maximum (1 RM), systolic blood pressure during muscle strengthening exercise was greater than during aerobic exercise at the anaerobic threshold (AT). However, the double product was not significantly different at any load level.

 Study 2 investigated the incidence of abnormal cardiovascular responses in the recovery phase of patients with myocardial infarction. Forty patients with myocardial infarction undergoing exercise therapy combined with weight training and 65 patients undergoing usual aerobic training alone served as subjects. Aerobic training was prescribed according to the heart rate at the AT level, and weight training of the knee extensors was carried out at a load level of 60% 1 RM. The incidence of arrhythmias, ischemic changes and heart failure was similar in the two groups : 25.0% in the weight training-combined group and 23.1% in the non-weight training group. Exercise therapy was discontinued because of abnormal cardiovascular responses in 10.0% of the weight training-combined group and 9.2% in the non-weight training group, with no significant differences between them. These results suggest that weight training at 40-60% 1 RM could be safely used for exercise therapy in the recovery phase of patients with myocardial infarction.
