EAC is a collapse in conscious athletes who are unable to stand or walk unaided as a result of light headedness, faintness and dizziness or syncope causing a collapse that occurs after completion of an exertional event. Although EAC is perhaps the most common aetiology confronted by the medical provider attending to collapsed athletes in a finish-line tent, providers must first maintain vigilance for other potential life-threatening aetiologies that cause collapse, such as cardiac arrest, exertional heat stroke or exercise-associated hyponatraemia. Previously, it has been believed that dehydration and hyperthermia were primary causes of EAC. On review of the evidence, EAC is now believed to be principally the result of transient postural hypotension caused by lower extremity pooling of blood once the athlete stops running and the resultant impairment of cardiac baroreflexes. Once life-threatening aetiologies are ruled out, treatment of EAC is symptomatic and involves oral hydration and a Trendelenburg position \u2013 total body cooling, intravenous hydration or advanced therapies is generally not needed.<\/jats:p>","DOI":"10.1136\/bjsports-2011-090378","type":"journal-article","created":{"date-parts":[[2011,9,26]],"date-time":"2011-09-26T22:05:24Z","timestamp":1317074724000},"page":"1157-1162","source":"Crossref","is-referenced-by-count":91,"title":["Exercise-associated collapse: an evidence-based review and primer for clinicians"],"prefix":"10.1136","volume":"45","author":[{"given":"Chad A","family":"Asplund","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis G","family":"O'Connor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy D","family":"Noakes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2011,9,26]]},"reference":[{"key":"2024051401462242000_45.14.1157.1","unstructured":"Running USA. 2010 Annual Marathon Report. http:\/\/www.runningusa.org\/node\/76115#76116 (accessed 27 June 2011)."},{"key":"2024051401462242000_45.14.1157.2","doi-asserted-by":"crossref","first-page":"1549","DOI":"10.1097\/00005768-200009000-00004","article-title":"A 12-yr profile of medical injury and illness for the Twin Cities Marathon","volume":"32","author":"Roberts","year":"2000","journal-title":"Med Sci Sports Exerc"},{"key":"2024051401462242000_45.14.1157.3","doi-asserted-by":"crossref","first-page":"226","DOI":"10.1249\/MSS.0b013e3181b1cdcf","article-title":"Determining a \u201cdo not start\u201d temperature for a marathon on the basis of adverse outcomes","volume":"42","author":"Roberts","year":"2010","journal-title":"Med Sci Sports Exerc"},{"key":"2024051401462242000_45.14.1157.4","doi-asserted-by":"crossref","first-page":"1595","DOI":"10.1249\/00005768-199512000-00003","article-title":"The prevalence and significance of post-exercise (postural) hypotension in ultramarathon runners","volume":"27","author":"Holtzhausen","year":"1995","journal-title":"Med Sci Sports Exerc"},{"key":"2024051401462242000_45.14.1157.5","first-page":"172","article-title":"Changes in body fluid composition and volume during vigorous exercise by athletes","volume":"11","author":"Cade","year":"1971","journal-title":"J Sports Med Phys Fitness"},{"key":"2024051401462242000_45.14.1157.6","doi-asserted-by":"publisher","DOI":"10.1172\/JCI105484"},{"key":"2024051401462242000_45.14.1157.7","first-page":"893","article-title":"The danger of an inadequate water intake during marathon running","volume":"43","author":"Wyndham","year":"1969","journal-title":"S Afr Med J"},{"key":"2024051401462242000_45.14.1157.8","doi-asserted-by":"publisher","DOI":"10.1097\/00000441-194706000-00001"},{"key":"2024051401462242000_45.14.1157.9","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1097\/00042752-199710000-00006","article-title":"Collapsed ultraendurance athlete: proposed mechanisms and an approach to management","volume":"7","author":"Holtzhausen","year":"1997","journal-title":"Clin J Sport Med"},{"key":"2024051401462242000_45.14.1157.10","unstructured":"OCEBM Levels of Evidence Working Group. \u201cThe Oxford 2011 Levels of Evidence\u201d.
