This function is even more evident during endurance exercise, with an increase in the ejection index of 4 times the resting values. Similarly, as a result of training, an adaptation occurs in cardiac morphology, in which the aorta undergoes a change in its structure that allows for better damping function. Athletes that adapt more may experience both of the heart chambers and the aorta, are those who demand a high cardiovascular stress, a high dynamic component and moderate static component. By using non-invasive measurements in humans (mainly echocardiography and MRI), the size of the aorta has been shown to increase in athletes with greater cardiovascular demands.</p></div>","PeriodicalId":34995,"journal":{"name":"Apunts Medicina de l''Esport","volume":"52 193","pages":"Pages 3-9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.apunts.2016.09.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85251892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
