Resumo: | Long lasting exertion induced stress can alter body homeostasis that can remain visible during several days and seem to be dependent from the training level of the subjects. This study intended to assess biochemical and body composition alterations induced by an ultramarathon in kayak. The subject was a male master kayaker, aged 48 years old and with near 30 years of continuous practice of kayaking. The ultramarathon was performed in River Douro, from Duruelo de la Sierra (Spain) till Oporto (Portugal), covering almost 1000 km within 17 days. Daily exertion varied from 55 km (the shortest stage) to 85 km (the longest stage). Body composition was assessed from skinfolds measurements; after an overnight fast blood samples were collected from antecubital vein, at rest, before and several moments after the ultramarathon. Some biological parameters (enzimes, electrolytes, clooting factors, blood chemistry) were assessed. It was stated a significant reduction of body weight and fat mass percent. The most significant alterations of biological indicators were, serum iron decrease and HDLc increase. . High basal values of urea and creatinina (some of them out of laboratorial reference) are unlikely related to the ultramarathon. Serum enzymes, evolving within the limits of laboratorial normality indicated absence of rabdomiólisis or hepatic and epithelial cell destruction. Other minerals studied (Ca, Na, K, Mg, Cl, P) evolved within the standard of normality. The low values of the coagulation indicators demonstrated a certain protection against thrombogenecity with low values of fibrinogen and low values of several clotting factors (II, V, VII, X), while clotting times were maintained within the values of laboratorial normality. The kayak ultramarathon, perhaps by the subjects’ high training level, didn’t induce alterations which can be considered as pathological, indicating good accommodation of the master kayaker to this kind of exertion. |

Este estudo pretendeu avaliar as alterações bioquímicas e da composição corporal induzidas pela realização de uma ultramaratona em kayak. O sujeito deste estudo era um canoísta veterano, de 48 anos de idade e cerca de 30 anos de prática ininterrupta de canoagem. A ultramaratona consistiu na descida do rio Douro, desde Duruelo de la Sierra (Espanha) até ao Porto (Portugal), num percurso de cerca de 1000 quilómetros, cumprido em 17 dias. A quilometragem diária variou entre 55km (a etapa mais curta) e 85km (a etapa mais longa). A composição corporal foi determinada pelo medição das pregas de adiposidade subcutânea. Após uma noite de jejum, foram recolhidas, em repouso, amostras de sangue da veia antecubital antes e vários momentos após a ultarmaratona. Foram avaliados vários parâmetros biológicos (enzimáticos, electrolíticos, bioquímicos e factores de caoagulação). Verificou-se uma significativa redução quer do peso corporal quer da percentagem de massa gorda. As alterações mais significativas dos indicadores biológicos foram a redução do ferro plasmático e o aumento das lipoproteínas de alta densidade (HDLc). Os elevados valores de uréia e creatinina (alguns fora dos valores de referência laboratorial) parecem não estar relacionados com a ultramaratona. As enzimas séricas não sofreram alterações significativas, indicando ausência de rabdomiólise ou destruição de tecido hepático e epitelial. Os restantes minerais estudados (Ca, Na, K, Mg, Cl, P) evoluiram dentro de um padrão de normalidade. Os valores baixos de fibrinogénio e dos factores de coagulação (II, V, VII, X) evidenciam certa protecção antitrombótica, enquanto os tempos de coagulação mantiveram-se dentro dos limites de normalidade laboratorial. A ultramaratona, talvez pelo elevado nível de treino do canoista em estudo, não provocou alterações que possam indiciar a entrada em situação patológica, indicando uma boa acomodação do sujeito a este tipo de esforço.Department of Physical Education - State University of Maringá (UEM), Maringá-PR, Brazil2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3274Journal of Physical Education; Vol 18 No 2 (2007); 1830189Journal of Physical Education; Vol. 18 Núm. 2 (2007); 1830189Journal of Physical Education; v. 18 n. 2 (2007); 18301892448-2455reponame:Journal of Physical Education (Maringá)instname:Universidade Estadual de Maringá (UEM)instacron:UEMporhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3274/2340Santos, José Augusto Rodrigues dosJorreto, MiguelSantos, Igor Fernandes dosinfo:eu-repo/semantics/openAccess2023-01-10T15:37:07Zoai:periodicos.uem.br/ojs:article/3274Revistahttp://periodicos.uem.br/ojs/index.php/RevEducFis/indexPUBhttps://old.scielo.br/oai/scielo-oai.php||revdef@uem.br2448-24552448-2455opendoar:2023-01-10T15:37:07Journal of Physical Education (Maringá) - Universidade Estadual de Maringá (UEM)false |
