摘要的重點如下，跟大家分享： 馬拉松訓練、自行車長征、鐵人競賽等長距離運動會造成 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 暫時且急性的動脈與右心室的血液量過載，也會造成右心室血液射出分率暫時降 低與心肌酵素增加，但這些狀況會在一周內回復正常(編按：反覆一直操當然就 不會恢復到正常) Patchy myocardial fibrosis, particularly in the atria, interventricular septum, and right ventricle, creating a substrate for atrial and ventricular arrhythmias 上述的狀況會造成心肌的塊狀纖維化，尤其是在動脈處、心室間隔與右心室等含 心肌纖維的地方，這些病變容易造成心律不整 long-term excessive sustained exercise may be associated with coronary artery calcification, diastolic dysfunction, and large-artery wall stiffening 長期過量持續運動也可能與冠狀動脈鈣化、心臟擴張失能與大動脈壁硬化有關 However, this concept is still hypothetical and there is some inconsistency in the reported findings 然而，這觀念仍為假設且有許多與上述不一致的例子（編按：此篇為review之 文章，意思就是結果不一致尚待考驗，只是部分個案是如此，非全部） Furthermore, lifelong vigorous exercisers generally have low mortality rates and excellent functional capacity 此外，終生且有活力的運動者一般來說有較低的死亡率與傑出的身體功能力 小弟的結論：持之有恆的運動、適度休息與保養身體才是王道，此篇僅供參考 英文篇名: Potential Adverse Cardiovascular Effects From Excessive Endurance Exercise 網路上可直接下載PDF 如有興趣討論全文的夥伴歡迎站內信 --
