[Comparative evaluation of the effectiveness of various physical training methods with patients who have had a myocardial infarct].

A total of 180 men were examined 4 months after myocardial infarction. The patients of the main group were randomised into subgroups according to the nature of physical training (PT). B2 subgroup did in-door therapy exercises with elements of games; B3 subgroup was assigned the same exercises, but received 5,2 mg of nitrong 1 hour prior to PT; B4 subgroup practiced bicycle ergometry with stable load comprising 50% of individual exercise tolerance. In B5 subgroup the stable load was 75% and in B6 subgroup the load was gradually increased (50-75-90% of individual exercise tolerance). All the patients participating in PT showed a considerable increase of the main indices of physical capacity (threshold power, maximal oxygen consumption, double product), which was accompanied by an improvement of their state and functional class. PT with pre-exercise nitrong, and bicycle ergometry with the load constituting 50% of the individual threshold power yielded the best results.
