title: [Optimal intensity and duration of training and the duration of walks during the after-care of myocardial infarct patients at a sanatorium].
abstract: Daily exercise drills producing a heart rate increment of about 31.5% of the one recorded at first stress tolerance test and lasting for 105 min, in combination with daily 75 minutes' walks were not sufficient to increase stress tolerance. More intensive drills, producing a 50.6% heart rate increment, while lasting less than 1 hour per day, in combination with 2.5 hours' daily walks, resulted in a significant stress tolerance increase. In neither of the two groups was it associated with any significant rise of the double product, implicating extracardiac factors as the principal contributors.
