[Organometric evaluation of heart changes during systematic physical exercise].
Hearts from 23 athletes who had died of traumas were investigated using a morphometric approach that involves external and internal macro-changes measurement, plani-and gravimetry, histostereometry, and morpho-statistical treatment. Hypertrophic heart was found in all the cases, while the ratios between quantitative parameters of individual heart muscle departments, as well as nuclear-cytoplasmatic and stromal-parenchymatous relationships and myocardial blood supply were within normal range. It was demonstrated that only a certain portion of myocardial muscular cells, responsible for intensified operation, became hypertrophic in response to systematic exercise.
