摘要的重点如下，跟大家分享： 马拉松训练、自行车长征、铁人竞赛等长距离运动会造成 transient acute volume overload of the atria and right ventricle, with transient reductions in right ventricular ejection fraction and elevations of cardiac biomarkers, all of which return to normal within 1 week 暂时且急性的动脉与右心室的血液量过载，也会造成右心室血液射出分率暂时降 低与心肌酵素增加，但这些状况会在一周内回复正常(编按：反覆一直操当然就 不会恢复到正常) Patchy myocardial fibrosis, particularly in the atria, interventricular septum, and right ventricle, creating a substrate for atrial and ventricular arrhythmias 上述的状况会造成心肌的块状纤维化，尤其是在动脉处、心室间隔与右心室等含 心肌纤维的地方，这些病变容易造成心律不整 long-term excessive sustained exercise may be associated with coronary artery calcification, diastolic dysfunction, and large-artery wall stiffening 长期过量持续运动也可能与冠状动脉钙化、心脏扩张失能与大动脉壁硬化有关 However, this concept is still hypothetical and there is some inconsistency in the reported findings 然而，这观念仍为假设且有许多与上述不一致的例子（编按：此篇为review之 文章，意思就是结果不一致尚待考验，只是部分个案是如此，非全部） Furthermore, lifelong vigorous exercisers generally have low mortality rates and excellent functional capacity 此外，终生且有活力的运动者一般来说有较低的死亡率与杰出的身体功能力 小弟的结论：持之有恒的运动、适度休息与保养身体才是王道，此篇仅供参考 英文篇名: Potential Adverse Cardiovascular Effects From Excessive Endurance Exercise 网路上可直接下载PDF 如有兴趣讨论全文的夥伴欢迎站内信 --
