[Fitness and stress tolerance of myocardial infarct rehabilitation in patients in relation to age].

Results on fitness and exercise tolerance of patients undergoing rehabilitation after myocardial infarction are shown in dependence on age. The fitness data of the patients recovering from myocardial infarction can be classified with the lower reference region of untrained normal populations and are subject to the same regularities in the ageing process. For sports therapy a versatile endurance training with average blood lactate concentrations of 2.5-3.5 mmol/l is recommended. The greater strain on the aerobic-anaerobic metabolism in older infarction patients during sports therapy emphasizes the necessity of the age-specific design of exercises.
