A prospective study was undertaken to determine the frequency of detectable gastrointestinal bleeding in participants of a 100-mile running race. Pre- and postrace questionnaires were utilized to determine training data, gastrointestinal symptoms, diet, and the use of medications during training and during the race, prior known gastrointestinal disease, and 100-mile race experience. Three prerace and the first three postrace stools were sampled for blood using the standard Hemoccult method in 35 runners: 85% of the participants who were Hemoccult negative before the race converted to positive in their postrace samples. Runners with the postrace Hemoccult-positive stools had more frequent and intense nausea, diarrhea, abdominal cramping, and bloating (P less than 0.05) during the race. Lower gastrointestinal symptoms correlated with Hemoccult positivity (P less than 0.05), whereas upper gastrointestinal symptoms did not. The majority of participants showed evidence of gastrointestinal bleeding after the race. Digestive symptoms are common and lower gastrointestinal symptoms correlate with gastrointestinal bleeding.
开展了一项前瞻性研究，以确定100英里长跑比赛参与者中可检测到的胃肠道出血的频率。赛前和赛后问卷用于确定训练数据、胃肠道症状、饮食、训练期间和比赛期间的药物使用情况、既往已知的胃肠道疾病以及100英里比赛经验。对35名跑步者的三份赛前粪便样本和赛后前三份粪便样本采用标准隐血试验方法进行血液采样：85%的赛前隐血试验阴性的参与者在赛后样本中转为阳性。赛后隐血试验阳性粪便的跑步者在比赛期间出现恶心、腹泻、腹部绞痛和腹胀的频率更高、程度更严重（P<0.05）。下胃肠道症状与隐血试验阳性相关（P<0.05），而上胃肠道症状则不然。大多数参与者在赛后显示出胃肠道出血的迹象。消化症状很常见，下胃肠道症状与胃肠道出血相关。
