不同体力活动水平高校女性教师递增负荷运动前后血清心肌酶的比较研究

目的：研究不同体力活动水平女性教师递增负荷前后血清心肌酶的差异，进而评估不同体力活动水平女性教师运动中可能出现的心脏风险。方法：对受试者进行体力活动问卷调查，从中筛选87名健康女性教师进行递增负荷试验，测试运动测试前后的心肌酶指标进行比较分析。结果：1）运动前安静状态下，体力活动不足组心肌酶各指标值均低于中、高水平体力活动组，其中体力活动不足组CK-MB显著的低于中等组（P<0.05）并且非常显著的低于高等组（P<0.01）。2）运动测试后，体力活动高水平组CK值显著的高于体力活动不足组（P<0.05），除AST以外，其余心肌酶水平随着体力活动水平的升高而升高。其中体力活动不足组AST值超过正常值范围，提示心肌组织出现了一定的损伤。3）除中等和高水平体力活动组的CK-MB运动后比运动前有所下降外，其余各组指标运动后都有所升高，特别是三组的CK、AST都非常显著的升高（P<0.01），从运动前后差值比较分析来看，不足组的CK、AST增加值显著的高于中等组和高等组（P<0.05）。结论：1. 体力活动不足的高校女性教师安静状态下的心肌酶水平较低。2. 递增负荷运动会引起高校女性教师心肌细胞出现一定程度的损伤，运动后血清心肌酶水平有所升高，而且体力活动不足女性的损伤更为严重，主要表现在心肌酶指标中的CK和AST。

Comparative Study of the Serum Enzyme Myocardial of College Female Teachers before and after the Incremental Load Exercise with Different Levels of Physical Activity

Objective: To study the different physical activity level the serum myocardial enzyme differences before and after the increasing load of female teachers, in order to assess the risk of heart may occur in different physical activity levels of female teachers during exercise. Methods: The subjects of physical activity questionnaire survey, selected from 87 healthy female teachers incremental load tests, the test exercise test before and after the cardiac enzymes indicators for comparative analysis. Results: 1) prior to exercise quiet state, lack of physical activity each index value set of cardiac enzymes were lower than in the high level of physical activity group, including lack of physical activity group CK-MB was significantly lower than the moderate group (P <0.05) and very significantly lower than the higher group (P <0.01). 2) after the exercise test, the high level of physical activity of CK value was significantly higher than the physical activity group (P <0.05), AST outside, the remaining enzyme levels with increasing physical activity levels rise. Lack of physical activity group AST values exceed the normal range, suggesting that the myocardial tissue damage. 3) In addition to the group of medium and high levels of physical activity, CK-MB after exercise than before exercise decline, the rest of the set of indicators after exercise has increased, in particular, the three groups of CK the AST have very significantly increased (P <0.01), from the comparative analysis of the difference before and after exercise, the insufficient group CK-MB, AST added value significantly higher than the middle group and advanced group (P <0.05). Conclusion: 1. Lack of physical activity, quiet state college female teachers under lower enzyme levels. 2. Increasing load Games a certain degree of damage caused by college women teachers myocardial cells appear somewhat elevated serum enzyme levels after exercise, and women''s lack of physical activity is a more serious injury, mainly in the indicators of cardiac enzymes CK and AST .
