The improved blood pressure, cholesterol levels and robust cardiac health that exercise has been proven to bestow? Among extreme exercisers, those blessings may be offset partially by an increased vulnerability to atrial fibrillation and coronary-artery plaque, suggests other recent studies.
如果上述说法成立,那跑马拉松能改善人的血压、胆固醇水平,并让心脏变得更为强健,这些已被证实的事又该作何解释?近来另一些研究表明,对于过度锻炼者而言,由于他们更易患上心房颤动和冠状动脉斑块的病症,所以跑马拉松带来的一部分好处可能会被抵消掉。
In the face of this research, long-standing skepticism about the possibility of 'exercise overdose' is softening among many sports physicians. 'The lesson I've learned from 40 years of cardiology is that when there's this much smoke, there's often some fire, ' said Paul Thompson, a sports-medicine specialist and veteran marathoner who is chief of cardiology at Hartford Hospital in Connecticut.
许多体育运动医学家一直都对存在“运动过量”这种可能性的说法表示质疑,但面对上述研究,他们中的很多人态度都在软化。康涅狄格州哈特福德医院(Hartford Hospital)心脏病学负责人、运动医学专家及马拉松老将保罗??汤普森(Paul Thompson)说:“四十年的心脏病学职业生涯教给我一点:无中不能生有,事出总是有因。”
