Home versus group exercise training for increasing functional capacity after myocardial infarction.

To evaluate the efficacy of exercise training for increasing functional capacity in the 6 months after clinically uncomplicated myocardial infarction, 198 men 52 +/- 9 years of age participated in a training study. They were randomly assigned to one of four exercise protocols: 8 to 26 weeks of training at home (group 1, n = 66) or in a group program (group 2, n = 61) following treadmill testing performed 3 weeks after infarction, treadmill testing at 3 weeks without subsequent training (group 3, n = 34), and treadmill testing for the first time at 26 weeks (control, n = 37). At 26 weeks functional capacity was significantly higher in patients training at home or in a group program than that in patients without training or in control patients: 8.1 +/- 1.5, 8.5 +/- 1.3, 7.5 +/- 1.8, and 7.0 +/- 1.7 METs, respectively (p less than .05 and p less than .001). No significant differences in functional capacity were noted between patients training at home and those in a group program. No training-related complications occurred. Home and group training are equally effective in increasing functional capacity of low-risk patients after myocardial infarction.
