During intensive growth of animals, the main parameters of myocardial contractility were reduced. Poststressor depression of the contraction of isolated papillary muscles was more marked in adult than in young animals. Thus, aging of animals was accompanied by reduced cardiac muscle contraction. It is inferred that strong stress influence might result in a deep depression of the cardiac function in question, threatening the physiological possibilities of adaptation.
在动物生长旺盛期，心肌收缩力的主要参数降低。应激后成年动物离体乳头肌收缩的抑制比幼年动物更明显。因此，动物衰老伴随着心肌收缩力下降。据推测，强烈的应激影响可能导致所述心脏功能的深度抑制，威胁生理适应能力。
