In response to a program of daily swimming for 16 weeks, the activities of pyruvate kinase and lactate dehydrogenase increased significantly in the hearts of young male rats. The isozyme composition in M of cardial lactate dehydrogenase increased from 28.5 to 32.7% in the trained animals. Phosphofructokinase activity and glycogen content were unchanged. The hearts of the exercising animals were 28% heavier than those of sedentary paired weight controls.
在一项为期16周的每日游泳计划的作用下，幼年雄性大鼠心脏中丙酮酸激酶和乳酸脱氢酶的活性显著增加。训练组动物心肌乳酸脱氢酶M同工酶的组成从28.5%增加到32.7%。磷酸果糖激酶活性和糖原含量未发生变化。运动组动物的心脏比久坐的配对体重对照组重28%。
