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...

J. Equine Sci. Vol. 18, No. 1 pp. 5–11, 2007 The following items were investigated to measure blood lactate in horses under field conditions using portable lactate analyzers recently developed for human athletes. 1) The precision of two types of portable lactate analyzer and the standard analyzer using the immobilized enzyme method, and correlation among the lactate concentrations measured by t...

Int J Exerc Sci 2(2): 83-93, 2009. The measurement of blood lactate has long been used as marker of exercise intensity and training status. We compared a commercially available lactate oxidase spectrophotometric method (LO) to determine blood lactate levels to two previously validated methods, the lactate dehydrogenase spectrophotometric method (LDH), and the YSI 1500L Sport lactate analyzer (Y...

conclusions amateur motocross riders had significant anaerobic metabolism demands and had reduced handgrip strength following a training session. these data suggest an importance of physical training aimed at improving anaerobic and neuromuscular performance of the upper limbs in amateur motocross riders. background motocross is one of the most popular motorized off-road sports, characterized b...

Classic neuroenergetic research has emphasized the role of glucose, its transport and its metabolism in sustaining normal neural function leading to the textbook statement that it is the necessary and sole metabolic fuel of the mammalian brain. New evidence, including the Astrocyte-to-Neuron Lactate Shuttle hypothesis, suggests that the brain can use other metabolic substrates. To further study...

introduction: the use of antioxidants before high-intensity training, which leads to the release of free radicals and muscle injuries, can result in reduced damage during exercise. accordingly, in this study, we aimed to evaluate the effect of selenium supplement intake on oxidative stress, following exhaustive aerobic exercise among young physically-active females. methods: in this quasi-exper...

BACKGROUND Timely identification of high blood lactate levels in septic patients may allow faster detection of those patients requiring immediate resuscitation. Point-of-care (POC) testing is being increasingly utilized in the emergency department (ED). We examined the accuracy and time-saving effect of a handheld POC lactate device for the measurement of fingertip and whole blood lactate as co...

The aim of the study was to explore the effect of lactate on insulin-stimulated glucose uptake in rats. Thirty Wistar rats, weighing 250 - 300 g. were arbitrarily divided into one of three groups (n =10): insulin (1 IU/kg) treated group, lactate (80 mg/kg), and insulin plus lactate treated groups. Blood glucose levels were measured in venous samples collected from the tail vein over 3 hour peri...

BACKGROUND Brain magnetic resonance spectroscopy (MRS) has been reported to be a valuable noninvasive tool in the diagnosis of some rare diseases. In this study, our aim was to assess lactate peak on single-voxel proton MRS in children with syndromic mitochondrial diseases (MDs). METHODS From March 2004 to November 2010, 14 patients who were diagnosed with syndromic MDs underwent single-voxel...

BACKGROUND Acute organophosphorus pesticide poisoning (AOPP) is becoming a significant problem and a potential cause of human mortality because of the abuse of organophosphate compounds. This study aims to determine the independent prognostic factors of AOPP by using multivariate logistic regression analysis. METHODS The clinical data for 71 subjects with AOPP admitted to our hospital were re...
