Influência da forma de indução à acidose na determinação da intensidade de lactato mínimo em corredores de longa distância

Abstract: Artigo originAl RESUMO O objetivo principal deste estudo foi verificar se diferentes formas de indução à acidose interferem na determinação da intensidade do lactato mínimo (LACmin) em corredores de longa distância. Desse modo, 14 corredores de provas fundas do atletismo participaram do estudo. Os atletas realizaram três protocolos: 1) teste incremental em esteira rolante, com incrementos de 1km.h-1 a cada três minutos até a exaustão, para a determinação das intensidades de limiar anaeróbio (OBLA), de limiar a… Show more

“…Despite being appropriate, the values found for peak lactate in the present study were lower than the ones obtained by other groups 10,14,18,22 . The literature is still controversial concerning the relation between peak lactate concentration and the results of the lactate minimum test 22,23 .…”

“…Despite being appropriate, the values found for peak lactate in the present study were lower than the ones obtained by other groups 10,14,18,22 . The literature is still controversial concerning the relation between peak lactate concentration and the results of the lactate minimum test 22,23 . In the present study, the LM concentrations in the two adjustments adopted were low (LM1 = 3.14 ± 0.29 mM and LM2 = 3.20 ± 0.33 mM) and significantly correlated with the lactate peak concentration (r = 0.78 and 0.76, respectively), suggesting that the lac peak value may generate different LM concentrations, but not distinct intensities (vLMs).…”

“…two efforts of 300 s separated by a 120 s passive interval). Therefore, although several studies have used stages of 180 s [10,17], some authors have suggested the use of longer stages for the determination of aerobic capacity through [Lac] (e.g. 360 s) [18].…”

“…Para la medición del lactato sanguíneo se utilizó un minifotómetro marca Dr Lange LP20 (Hach Lange, Düsseldorf, Alemania), que posee rangos de medición de 0 a 30 mmol/lt, y reactivos Dr. Lange LKM 140 para lactato. Se siguieron las recomendaciones de diversos autores (Dassonville et al, 1998;Santhiago, Silva, Guglielmo, & Higino, 2008), con una lanceta desechable y capilares con heparina se colectaron 10ul de sangre desde el lóbulo de la oreja, luego se depositó la muestra en los tubos reactivos para lactato y se introdujo en la celda fotosensible del minifotómetro. En todos los casos se respetó el proceso de limpieza y asepsia, utilizando técnicas de enfermería habituales.…”
