One of the most popular dairy products worldwide is yogurt, which flavor highly influenced by lactic acid content. Yogurts with fruit preparations contain polyphenols, secondary plant metabolites proven antioxidant properties. As there no data regarding neither lactate nor polyphenol content in commercial yogurts Serbia, this study aimed to determine and levels, as well activity selected yogurt...

High-intensity exercise training contributes to the production and accumulation of blood lactate, which is cleared by active recovery. However, there is no commonly agreed intensity or mode for clearing accumulated blood lactate. We studied clearance of accumulated blood lactate during recovery at various exercise intensities at or below the lactate threshold after high-intensity interval runs ...

We evaluated: the agreement between lactate minimum and maximal lactate steady state (MLSS) cycling powers (study 1); whether rates of change of blood lactate concentration during the lactate minimum test reflect that of constant power exercise (study 2); whether the lactate minimum power is influenced by the muscle groups used to elevate blood lactate concentration (study 3). Study 1: 32 subje...

A lactate-fermenting strain of Selenomonas ruminantium (HD4) and a lactatenonfermenting strain (GA192) were examined with respect to the stereoisomers of lactate formed during glucose fermentation, the stereoisomers of lactate fermented by HD4, and the characteristics of the lactate dehydrogenases of the strains. GA192 formed L-lactate and HD4 formed L-lactate and small amounts of D-lactate fro...

background: consumption of energy drinks has become widespread among athletes. the effectiveness of red bull and hype energy drinks on selected indices of maximal cardiorespiratory fitness and blood lactate levels in male athletes was examined in this study. methods: ten male student athletes (age: 22.4 ± 2.1 years, height: 180.8 ± 7.7 cm, weight: 74.2 ± 8.5 kg) performed three randomized maxim...

background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...
