通过对大鼠1次力竭性游泳和4周耐力性游泳训练后锌、铜代谢及血清碱性磷酸酶(ALP)、乳酸脱氢酶(LDH)活性变化的研究,结果发现:1)1次力竭性游泳运动导致大鼠锌、铜在体内重新分配,即通过血液运输,从骨骼肌向肝脏、心脏转移。2)4周耐力性游泳训练使大鼠机体增加对锌的储存,大鼠不表现锌缺乏,但大鼠体内铜储量下降,有导致缺乏可能。3)1次力竭性游泳运动后大鼠血清碱性磷酸酶、乳酸脱氢酶活性升高,但这些酶活性的升高与血清锌浓度上升没有明显相关关系。4)4周耐力性游泳训练使大鼠安静时血清乳酸脱氢酶活性升高,说明长期耐力运动有选择性导致某些血清酶活性升高的可能。
By studying the changes of zinc and copper metabolism and serum alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activity after exhaustive swimming and 4-week endurance swimming training in rats, it was found that: 1) 1 Eruptive swimming led to the redistribution of zinc and copper in the body, that is, from the skeletal muscle to the liver and heart through blood transport. 2) 4-week endurance swimming training increased the body’s storage of zinc in rats, rats did not show zinc deficiency, but the body of copper in rats decreased, leading to lack of possibility. 3) Serum alkaline phosphatase and lactate dehydrogenase activity increased after one exhaustive swimming exercise, but there was no significant correlation between the increase of these enzyme activities and serum zinc concentration. 4) 4-week endurance swimming training makes serum lactate dehydrogenase activity in rats quiet, indicating that the long-term endurance exercise may lead to the increase of some serum enzyme activity.
