近年来,Blacklook(1977)提出在长跑时膀胱可受损伤或挫伤面致血尿。当我们考虑长跑引起胃肠道失血的机制时,也要联想到Blacklock提出的假说,成年男性运动员缺铁通常是胃肠道出血的结果,但这种可能性仅为近年来对长跑者才想到。1969年克莱顿在鹿特丹创造马拉松跑世界最好成绩后就曾呕吐出黑色液体和出现黑便。至今有关长跑后出现黑便已有多例报告,新近Papaioannides(1984)报告3例,其中1例诊断为出血性胃炎.Thompson(1982)报告1名进行健身跑后致死的原因为出血性胃炎。更多的是长跑者未足够重视胃肠道出血,因不少人是便潜血阳性。
In recent years, Blacklook (1977) has suggested that the bladder may be damaged or contused to cause hematuria during a long run. When we consider the mechanism by which long-distance running causes gastrointestinal bleeding, it is also reminiscent of the hypothesis raised by Blacklock that iron deficiency in adult male athletes is often the result of gastrointestinal bleeding but that this is only possible for long-distance runners in recent years . In 1969, Clayton vomited black liquid and black stool after creating the world marathon run best in Rotterdam. So far, there have been many reports of black stools after long-distance running. Recently, Papaioannides (1984) reported 3 cases, of which 1 case was diagnosed as hemorrhagic gastritis. Thompson (1982) reported a cause of hemorrhagic gastritis after being exhausted. More long-distance runners do not pay enough attention to gastrointestinal bleeding, because many people are occult blood positive.
