| 目的：观察不同运动时长易筋经锻炼对健康老年人心脏形态结构、左心室泵血功能、左心室收缩功能的影响。方法：健康老年人58例分为A组30例和B 组28例，A组和B组成员每次分别练习10min和20min的易筋经十二式。锻炼前后检测心脏功能，包括左心室收缩末期内径(ESD）、左心室舒张末期内径（EDD）、左心室舒张末期容量（EDV）、每搏输出量（SV）、每分输出量（CO）、心脏指数（CI）、射血分数（EF）以及短轴收缩率（FS）。结果：锻炼12周后，心脏功能检测显示，2组EDV、EDD、SV、CI、EF、FS等各项指标均较锻炼前增加，而ESD有一定程度的下降，其中B组SV、CI、EF锻炼前后差异具有统计学意义(P<0.05)；锻炼后2组间各项指标比较差异无统计学意义。结论：2组运动时长均对心脏的形态结构产生一定的变化趋势，20min运动时长可使左心室的泵血功能显著改善，但收缩功能无显著变化。从改善心脏功能方面考虑，20min运动时长值得推荐。 |

| Objective:To observe the effect of different exercise durations of YiJinJing on cardiac structure,left ventricular pump function and left ventricular systolic function of the healthy elderly.Methods:Fifty-eight healthy volunteers aged from 60 to 70 were divided into two groups:group A,30 cases,10 min 12-movements-YiJinJing exercise;group B,28 cases,20 min 12-movements-YiJinJing exercise.Cardiac functions,including indexes of end systolic dimension (ESD),end diastolic dimension (EDD),end diastolic volume (EDV),stroke volume (SV),cardiac output (CO),cardiac output index (CI),fractional shortening (FS) and ejection fraction (EF),were measured by using heart ultrasound before and after exercises.Results:At 12th week after exercises,the indexes of ESD,EDV,EDD,SV,CI,EF and FS in both groups were increased,but ESD was decreased.The scores of SV,CI,EF in group B showed significantly differences(P<0.05).There was no significant difference in each index between two groups after exercises.Conclusion:There are certain trends on cardiac morphology and structure in two exercise groups.Exercise of 20 min duration can improve the left ventricular pump function,but there is no significant difference in contraction function.From the consideration of improving cardiac function,exercise of 20-min duration is recommendable. |
