The content of potassium ions in rat liver mitochondria after intensive physical work (continuous swimming) is increased approximately 2-fold, while the rate of K+ efflux from the mitochondria is significantly reduced. A considerable increase of the "calcium capacity" and a decrease of the respiration rate in state 4 were found. The experimental results indicate that during intensive physical work the mitochondrial membrane resistance to the damaging effects is enhanced. A possible mechanism of these changes is discussed.
高强度体力劳动（持续游泳）后大鼠肝脏线粒体中的钾离子含量增加了约2倍，而线粒体中钾离子外流速率显著降低。同时发现“钙容量”显著增加，状态4下的呼吸速率降低。实验结果表明，在高强度体力劳动期间，线粒体膜对损伤作用的抗性增强。文中讨论了这些变化可能的机制。
