Effect of Lactate Consumption on Exercise Performance.

Effects of Ingestion of Bicarbonate, Citrate, Lactate, and Chloride on Sprint Running

“…Ϫ ϩ 2 H ϩ 3 C 6 H 12 O 6 [2] In the present study, we have therefore compared the effects on performance of ingestion of the three buffers: sodium bicarbonate, sodium citrate, and sodium lactate. As a placebo, we chose sodium chloride (12) rather than calcium carbonate (24), to control for any effect of sodium intake on performance through changes in intravascular volume (12).…”

“…A number of researchers have investigated the influence of polylactate ingestion on endurance performance (2,3,19,22), since Brooks (1) found that lactate can serve as an energy source for exercising muscles. In the study of Fahey et al (3), the ingestion of 80% polylactate and 20% sodium lactate as a 7% solution in water increased blood pH and bicarbonate compared to ingestion of a glucose polymer drink.…”

Interaction of carbohydrate metabolism and rat liquid gastric emptying in sustained running

“…It is well known that the fuel store to supply an urgent energy requirement such as sustained exercise comes in the form of plasma glucose, muscle glycogen, liver glycogen and finally fat 30 . It is crucial to maintain blood glucose during exercise 15,31 . Oxygen delivery and removal of carbon dioxide are essential in sustained exercise; lack of oxygen supply in turn leads to intramuscular lactate production 15 .…”

“…Because plasma glucose is the first energy source to supply an urgent demand, 15 our observation of hypoglycemia in untrained rats following 1 h running appears logical owing to rapid energy exhaustion. Similarly, trained cyclists have lower blood glucose level immediately after 1‐h exercise, whereas their glucose levels are restored in those receiving glucose infusion 31 . Increased glucose availability is thus beneficial to prevent further hepatic glucose production 35 .…”

Efeitos da suplementação crônica de lactato de cálcio e bicarbonato de sódio sobre desempenho físico em exercício intermitente de alta intensidade

“…Conforme a literatura tem apresentado, os estudos que investigaram o lactato, como um substrato energético, não apresentaram melhora no desempenho aeróbio (BRYNER et al, 1998;NORTHGRAVES et al, 2014;PEVELER e PALMER, 2012;SWENSEN et al, 1994). Contudo, apenas um estudo apresentou resultados positivos, com uma grande melhora de 25% no desempenho aeróbio (AZEVEDO et al, 2007).…”
