Prolonged restriction of rat mobility resulting in stoppage of the body and heart mass growth was accompanied by the increased contraction and relaxation velocity of isolated papillary muscles. Absolute values of the poststressor decrease in the main parameters of myocardial contractility in prolonged hypokinesia-exposed animals did not substantially differ from those in controls. The resultant functional significance of such a depression was less dangerous. The data suggest that the increased resistance of the animal body, particularly of the heart muscle to the damaging effect of acute stress in prolonged hypokinesia is an essentially stressful state.
大鼠活动受限时间延长导致身体和心脏质量增长停滞，同时伴有离体乳头肌收缩和舒张速度加快。长期处于运动功能减退状态的动物，应激后心肌收缩力主要参数下降的绝对值与对照组相比无显著差异。这种功能下降的最终影响危险性较低。数据表明，在长期运动功能减退状态下，动物机体，尤其是心肌对急性应激损伤作用的抵抗力增强，这本质上是一种应激状态。
