Single Sodium Pyruvate Ingestion Modifies Blood Acid-Base Status and Post-Exercise Lactate Concentration in Humans
This study examined the effect of a single sodium pyruvate ingestion on a blood acid-base status and exercise metabolism markers. Nine active, but non-specifically trained, male subjects participated in the double-blind, placebo-controlled, crossover study. One hour prior to the exercise, subjects ingested either 0.1 g·kg(-1) of body mass of a sodium pyruvate or placebo. The capillary blood sam...
متن کاملMetabolic control of muscle blood flow during exercise in humans.
During muscle contraction, several mechanisms regulate blood flow to ensure a close coupling between muscle oxygen delivery and metabolic demand. No single factor has been identified to constitute the primary metabolic regulator, yet there are signal transduction pathways between skeletal muscle and the vasculature that induce vasodilation. A link between muscle metabolic events and microvascul...
متن کاملSkeletal muscle blood flow and flow heterogeneity during dynamic and isometric exercise in humans.
The effects of dynamic and intermittent isometric knee extension exercises on skeletal muscle blood flow and flow heterogeneity were studied in seven healthy endurance-trained men. Regional muscle blood flow was measured using positron emission tomography (PET) and an [(15)O]H(2)O tracer, and electromyographic (EMG) activity was recorded in the quadriceps femoris (QF) muscle during submaximal i...
متن کاملRole of endothelin-1 in choroidal blood flow regulation during isometric exercise in healthy humans.
PURPOSE There is evidence that the choroid has some autoregulatory capacity in response to changes in ocular perfusion pressure (OPP). The mediators of this response are hitherto unidentified. The hypothesis for the current study was that endothelin (ET)-1 and/or angiotensin (ANF)-II may be involved in choroidal vasoconstriction during an increase in OPP. METHODS To test this hypothesis a ran...
متن کاملBlood Gas Analysis and Acid–base Disturbances
V . O2 is identical to tissue V . O2. This is extremely diffi cult to achieve clinically, particularly in mechanically ventilated subjects. Also determination of V . O2 becomes progressively less accurate as FIO2 increases. Various alternative means of measuring V . O2 which overcome some of these diffi culties are available and may be more appropriate for clinical use. For example, a pneumotac...
