Resumo: | Among the main physiopathological mechanisms in the appearance of injuries related to the physical exercise, the involvement of free radicals is very important, mainly oxygen reactive species. They can lead to hematologicaland biochemical alterations related to injuries mediated by the physical effort. For the prevention and treatment of such conditions, the use of antioxidant supplementation, like ?-tocopherol (vitamin E) and selenium has been considered for training animals and competitions of high impact. The aim of this research was to evaluate the influence of vitamin E and selenium oral supplementation on hematological parameters, the seric activity of muscular enzymes and the level of substances derived from oxidative stress on erythrocyte membranes of horses normally trained and submitted to a show jumping test. For this purpose, 20 horses with these characteristics were divided in two groups. One of them (GT) received oral supplementation of vitamin E (2500 mg/day) and selenium (3 mg/day) for 45 days and another one was kept as control (GC). Both groups were submitted to a standardized test of show jumping and samples of blood were collected in rest, immediately after, and 6, 12 and 24 hours after the end of the activity. The constituents of the hemogram, the seric activity of enzymes CK, AST, and LDH, and the level of an oxidative stress marker (TBARS) in erythrocyte membranes were evaluated. The number of erythrocytes and leukocytes returned to basal levels in GT after 6 hours. In GC, such values returned to rest levels between 12 and 24 hours. Despite the observed differences in some hematological parameters dynamics between the two groups, it was not possible to determine antioxidant activity in GT. These observations demonstrate the need for more studies to understanding oxidative stress effects on athletics horses and the use of antioxidants for these animal’s diets.KEY WORDS: Exercise, horse, oxidative stress, selenium, vitamin E. |

Avaliou-se a influência da suplementação oral à base de ?-tocoferol (vitamina E) e selênio sobre o quadro hematológico, bem como a atividade sérica de enzimas marcadoras de lesão muscular e o nível de substâncias derivadas da ação dos radicais livres sobre biomoléculas presentes na membrana de eritrócitos (TBARS) de equinos normalmente treinados e submetidos à prova de hipismo clássico. Para isso, distribuíram-se vinte cavalos em dois grupos, sendo um suplementado com produto à base de vitamina E (2500 mg/dia) e selênio (3 mg/dia) por 45 dias (GT) e outro mantido como controle (GC). Colheram-se amostras de sangue antes (TR) e após (T0) a realização do exercício e seis (T6), doze (T12) e 24 horas (T24) após o término da atividade de esforço. Foram avaliados os constituintes do hemograma, a atividade sérica das enzimas CK, AST e LDH e a concentração TBARS na membrana de eritrócitos. A suplementação utilizada apresentou efeito sobre alguns parâmetros do hemograma, uma vez que no GT houve retorno aos níveis basais de número de hemácias e leucócitos, caracterizado por neutrofilia, em até seis horas. No GC, tais valores retornaram aos níveis de repouso entre 12 e 24 horas. Para a AST, o GT retornou ao valor do repouso seis horas após a realização do exercício. No entanto, não houve efeito sobre as enzimas CK e LDH, nem para o TBARS. Apesar de terem sido observadas diferenças na dinâmica de alguns parâmetros hematológicos entre os grupos, não foi possível determinar atividade antioxidante no GT no delineamento experimental utilizado, o que demonstra a necessidade de mais estudos para o entendimento do estresse oxidativo em cavalos atletas e a suplementação com antioxidantes na dieta desses animais.PALAVRAS-CHAVES: Cavalo atleta, estresse oxidativo, fisiologia do exercício, vitamina E.Universidade Federal de Goiás2009-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa originalapplication/pdfhttps://revistas.ufg.br/vet/article/view/479310.5216/cab.v10i3.4793Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 3 (2009); 790-801Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 3 (2009); 790-8011809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/4793/5396Dias, Domingos Cachineiro RodriguesRocha, Juliana da SilvaGusmão, Alberto LopesEl-Bachá, Ramon dos SantosAyres, Maria Consuêlo Caribéinfo:eu-repo/semantics/openAccess2009-09-30T20:55:22Zoai:ojs.revistas.ufg.br:article/4793Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:17.278325Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
