Resumo: The progressive part of lactate minimum test (LMT) begins after induction of metabolic acidosis, followed by resting, aiming to reach the peak of lactate [LACpeak], to achieve the “U” shape curve. However, [LACpeak] is not inserted into the calculations. The present study aimed to suggest a new proposal of determination of metabolic transition (MT) by LMT, or either, to evaluate the curve [LAC] versus time of exercise (A) instead of [LAC] versus exercise intensity (B), including the [LACpeak] value. Wistar rats, adults (90 days) and non-exercised ones were evaluated by LMT for determination of minimum blood lactate (MBL). The MBL values, when analyzed the curve (A), did not show difference if compared with the values obtained by curve (B). There was not difference between exercise loads obtained in both curves. We suggest, then, a potential application of the new proposal to estimate the MBL in rats.

No entanto, [LACpico] não é inserido nos cálculos. O presente estudo objetivou apresentar nova proposta de determinação da transição metabólica (TM) através do TLM, ou seja, avaliar a curva [LAC] vs tempo de exercício (A), ao invés de [LAC] vs intensidade de exercício (B), incluindo-se o valor de LACpico. Ratos wistar, adultos (90 dias) e sedentários foram avaliados pelo TLM para a determinação do lactato sanguíneo mínimo (LSM). Os valores de LSM, quando analisada a curva (A), não mostraram diferença se comparados com valores obtidos através da curva (B). Não houve, também, diferença entre as cargas de exercício obtidas através destas curvas. Sugerimos, então, uma potencial aplicação da nova proposta na estimativa do LSM em ratos.Department of Physical Education - State University of Maringá (UEM), Maringá-PR, Brazil2008-05-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3406Journal of Physical Education; Vol 16 No 1 (2005); 73-78Journal of Physical Education; Vol. 16 Núm. 1 (2005); 73-78Journal of Physical Education; v. 16 n. 1 (2005); 73-782448-2455reponame:Journal of Physical Education (Maringá)instname:Universidade Estadual de Maringá (UEM)instacron:UEMporhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/3406/2436Voltarelli, Fabrício AzevedoMello, Maria Alice Rostom deGobatto, Claudio Alexandreinfo:eu-repo/semantics/openAccess2023-01-10T15:37:12Zoai:periodicos.uem.br/ojs:article/3406Revistahttp://periodicos.uem.br/ojs/index.php/RevEducFis/indexPUBhttps://old.scielo.br/oai/scielo-oai.php||revdef@uem.br2448-24552448-2455opendoar:2023-01-10T15:37:12Journal of Physical Education (Maringá) - Universidade Estadual de Maringá (UEM)false
