The findings build on previous results, like a famous analysis of more than 73,000 finishers of the 90-kilometre Vasaloppet ski race in Sweden over the course of a decade. In that study, those who completed the race once had half the risk of dying during the follow-up period compared to the general population; six-time finishers had less than a third of the standard mortality risk.
瑞典科学家收集了20多万名瑞典瓦萨滑雪赛选手的医疗记录。发现，参加比赛次数最多或最快的男性滑雪运员，在接下来的几年里比其他人（无论是否滑雪）更有可能患有心脏房颤。
今年4月份发表在《运动医学临床杂志》上的最新研究强化了这一观点，该研究在2021年向942名男性和女性长期耐力运动员收集了医疗和训练数据。所有人都曾参加过地方或国家级别的比赛，而且大多数人仍然参加比赛。这些运动员中约有20%（几乎全部是中年男性）表示，他们被诊断出患有房颤。其中百分之三曾中风。
与滑雪运动员一样，那些训练最多的运动员（从比赛年数和每周锻炼时间来看）患心房颤动的风险最高，尤其是男性运动员，更令人惊讶的是有游泳运动员（包括铁人三项运动员）。

数据多的是，就看你挑哪些来看。大家根据自己情况爱好来生活就好。不勉强自己，更不对他人的选择指指点点。
拿着运动选手的数据往自己身上套，有些抬举自己。即使是狂热运动爱好者，和那些高级专业运动员相比都是小打小闹。
