| 摘 要： | 为探讨游泳训练对大鼠心肌能量代谢相关酶类活性的影响,采用实验法对大鼠游泳训练前后的心肌琥珀酸脱氢酶（SDH）、苹果酸脱氢酶（MDH）、肌酸激酶（CK）和Na＋-K＋-ATP酶活性进行测定。结果表明：各状态下训练组大鼠的SDH活性均低于对照组,且在力竭时显著低于对照组（P〈0.01）;训练组在力竭即刻和24 h恢复时的MDH活性显著高于对照组（P〈0.05）;训练组在力竭即刻、恢复12h和恢复24h时的CK活性显著高于对照组（P〈0 05）;训练组在运动1 h、力竭即刻、恢复12 h和恢复24 h时的Na＋-K＋-ATP酶活性均高于对照组,但无显著差异。结论表明：游泳训练能促进大鼠心肌MDH、CK、Na＋-K＋-ATP酶等能量代谢相关酶活性升高,却使大鼠心肌胞浆中SDH活性降低,最终增强心肌有氧供能能力,提高运动能力。

| Abstract: | To explore the effects of swimming training on the energy metabolism enzymes activity of mice's heart muscle,the method of experiment is taken to test the mice's SDH,MDH,CK and the enzymes activity of Na+-K+-ATP.The results show that the SDH activity level of training group in different conditions is all lower than that of control group,while significantly lower as the mice are exhausted(P<0.01);the MDH activity level in the strength using up state and 24-hour-recovery state is significantly higher than tha... |
