Recent literature suggests reduced benefits associated with high intensity (HIT) and or sustained intensity exercise training (SIT). While important, they tend to contrast with other studies of HIT and SIT and may not be representative of all individuals wishing to participate in activities such as marathon running. The purpose of this observational report is to describe a 45-year history of 54 long distance runners, their incidence of death from cardiovascular disease and their ages at death compared to the normal population.
Data were collected longitudinally on all 54 members of a Southern California mens running club by the author, a cardiologist with 45 years of experience, member of the running club, and personal physician for most of the men for over 40 years. Retrospective and observational data were collected from direct professional and personal contact with the 54 men in the running club.
Closely monitored group of marathon runners with extreme HIT and SIT revealed a low incidence of cardiovascular disease (CVD) with an extended longevity relative to the general population.
The benefits of exercise for reducing risk of chronic disease, including CVD, are well known. Whether these benefits extend to the more intense and prolonged exercise associated with marathon running is unclear. However, as evidenced in the observational data presented here, at least in some populations, years of high-intensity, prolonged exercise may not be as toxic as suggested by others. Whether this is due to self-selection or predisposition is not well understood but merits further study.
近期文献表明，高强度（HIT）和/或持续强度运动训练（SIT）带来的益处有所减少。尽管这些文献很重要，但它们往往与其他关于HIT和SIT的研究结果相悖，可能并不代表所有希望参加马拉松跑步等活动的个体。本观察性报告的目的是描述54名长跑运动员45年的病史、他们心血管疾病的死亡率以及与正常人群相比的死亡年龄。
作者，一位拥有45年经验的心脏病专家、跑步俱乐部成员以及大多数成员40多年的私人医生，对南加州一个男子跑步俱乐部的所有54名成员进行了纵向数据收集。通过与跑步俱乐部的54名男性进行直接的专业和个人接触，收集回顾性和观察性数据。
对一组密切监测的马拉松运动员进行的极端HIT和SIT研究显示，与普通人群相比，他们的心血管疾病（CVD）发病率较低，寿命更长。
运动对降低包括CVD在内的慢性病风险的益处是众所周知的。这些益处是否能扩展到与马拉松跑步相关的更剧烈和持久的运动尚不清楚。然而，正如这里所呈现的观察性数据所示，至少在某些人群中，多年的高强度、持久运动可能并不像其他人所认为的那样有害。这是由于自我选择还是易感性尚不清楚，但值得进一步研究。
