'Heart disease comes from inflammation and if you're constantly, chronically inflaming yourself, never letting your body heal, why wouldn't there be a relationship between over exercise and heart disease?' said John Mandrola, a cardiac electrophysiologist and columnist for TheHeart.org.
心脏电生理学家、TheHeart.org的专栏作者约翰??曼德罗拉(John Mandrola)说:“心脏病源自炎症,如果你长期受慢性炎症困扰,从不让自己的身体痊愈,那么,过度锻炼和心脏病之间怎么可能会没有关系呢?”
Yet sports-medicine specialists are sharply divided over whether any warning is warranted. For every American who exercises to extremes, after all, there are thousands who don't exercise at all─and who might embrace any exercise-related warnings as cause for staying sedentary. Moreover, the evidence for extreme-exercise hazards is far from conclusive─and is contradicted by other studies suggesting the health benefits of exercise may accrue to infinity.
然而,在是否有必要就此发出警告的问题上,运动医学专家们的分歧很大。毕竟,按美国的人口比例来算,与每一名运动强度直逼极限的人相对应的是成千上万名根本不运动的人──任何与运动相关的警告都有可能成为他们继续坐着不动的理由。此外,“过度锻炼是危险的”这一说法还缺少证据,远未形成定论──而且与其他的研究结果也相矛盾,后者认为无止境的锻炼会有益于身体健康。
