Endurance training over 3, 10 or 20 days increased the activity of prolyl 4-hydroxylase (PH) in the left ventricle of mice. No increase was observed in the weight of the left ventricle, in galactosylhydroxylysyl glucosyltransferase activity or in hydroxyproline concentration. The increase in PH suggests that the synthesis of collagen increases during physiological adaptation of the heart to endurance exercise without changes in the ventricle weight or its total collagen content.
持续3天、10天或20天的耐力训练增加了小鼠左心室中脯氨酰4-羟化酶（PH）的活性。在左心室重量、半乳糖基羟赖氨酰葡糖基转移酶活性或羟脯氨酸浓度方面未观察到增加。PH的增加表明，在心脏对耐力运动的生理适应过程中，胶原蛋白的合成增加，而心室重量或其总胶原蛋白含量没有变化。
