O impacto dessas maratonas consecutivas sobre o sistema cardiovascular permanece desconhecido.  Objetivo  Monitorar o sistema cardiovascular para avaliar quaisquer adapta\u00e7\u00f5es cardiovasculares do atleta ao longo do per\u00edodo.  M\u00e9todos  Durante a avalia\u00e7\u00e3o pr\u00e9-estudo, conduzimos uma avalia\u00e7\u00e3o cl\u00ednica pr\u00e9-participa\u00e7\u00e3o (APP) composta por anamnese, eletrocardiograma, exame de sangue e capacidade funcional por meio do teste cardiopulmonar no exerc\u00edcio (TCPE). Durante o acompanhamento, o TCPE seriado, a avalia\u00e7\u00e3o da composi\u00e7\u00e3o corporal, a an\u00e1lise de amostra de sangue e o ecocardiograma foram realizados periodicamente, por 12 meses.  Resultados  Na APP, indiv\u00edduo do sexo masculino, 43 anos, altura: 1,83 m, peso: 76,9 kg, consumo m\u00e1ximo de oxig\u00eanio (VO2m\u00e1x): 52 ml\/kg\/min, gordura corporal: 12,6%, press\u00e3o arterial sist\u00f3lica e diast\u00f3lica: 120\/80 mmHg, glicemia: 92 mg\/dL, colesterol total: 185 mg\/dL, prote\u00edna C reativa de alta sensibilidade (hs-CRP): 0,08 mg\/dL, creatina fosfoquinase (CPK): 183 U\/L e troponina T de alta sensibilidade (hs-TnT): 7,1 ng\/L. Durante o acompanhamento, a m\u00e9dia de VO2m\u00e1x permaneceu em 48,7 \u00b1 1,2 ml\/kg\/min, a Fra\u00e7\u00e3o de Eje\u00e7\u00e3o do Ventr\u00edculo Esquerdo (FEVE) em 62 \u00b1 2%, o strain longitudinal global do VE em 19 \u00b1 1%, o \u00edndice de massa do VE em 83 \u00b1 7 g\/m2, o hs-CRP em 0,07 \u00b1 0,01 mg\/L, a CPK em 169 \u00b1 36 U\/L, a hs-TnT em 8,2 \u00b1 1,4 ng\/L e nenhuma arritmia maligna foi observada.  Conclus\u00e3o  O sistema cardiovascular do atleta se adaptou a um volume extremamente alto de maratonas consecutivas em intensidade moderada por 1 ano e permaneceu funcional na faixa de normalidade. Al\u00e9m disso, o atleta estabeleceu um novo recorde mundial de maratonas consecutivas, reconhecido pelo Guinness World Records.<\/jats:p>","DOI":"10.36660\/abc.20240838","type":"journal-article","created":{"date-parts":[[2025,7,10]],"date-time":"2025-07-10T14:02:16Z","timestamp":1752156136000},"source":"Crossref","is-referenced-by-count":0,"title":["Recorde de Resist\u00eancia em 366 Maratonas durante 366 Dias: Um Estudo de Caso"],"prefix":"10.36660","volume":"122","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8709-8706","authenticated-orcid":false,"given":"Francis Ribeiro de","family":"Souza","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renato Delascio","family":"Lopes","sequence":"additional","affiliation":[{"name":"Duke University Hospital,  EUA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6477-8741","authenticated-orcid":false,"given":"Guilherme Wesley Peixoto da","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil; Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Bellio de Mattos","family":"Barretto","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Carlos","family":"Battaglia Filho","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata Margarida do","family":"Val","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Kalil-Filho","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil; Hospital S\u00edrio Liban\u00eas,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria-Janieire de Nazar\u00e9 Nunes","family":"Alves","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"22636","published-online":{"date-parts":[[2025]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1113\/jphysiol.2007.143834","article-title":"Endurance Exercise Performance: The Physiology of Champions","volume":"586","author":"Joyner MJ","year":"2008","journal-title":"J Physiol"},{"issue":"1","key":"ref2","doi-asserted-by":"crossref","DOI":"10.1186\/s40798-015-0007-y","article-title":"Running Economy: Measurement, Norms, and Determining Factors","volume":"1","author":"Barnes KR","year":"2015","journal-title":"Sports Med Open"},{"issue":"15","key":"ref3","doi-asserted-by":"crossref","first-page":"1485","DOI":"10.1056\/NEJMc1900771","article-title":"Record-Breaking Performance in a 70-Year-Old Marathoner","volume":"380","author":"Robinson AT","year":"2019","journal-title":"N Engl J Med"},{"key":"ref4","series-title":"Belgian Stefaan Engels Completes Record 365th Marathon","year":"2011"},{"issue":"3","key":"ref5","first-page":"326","article-title":"The Brazilian Society of Cardiology and Brazilian Society of Exercise and Sports Medicine Updated Guidelines for Sports and Exercise Cardiology -
