Abstract:
This study examined the effect of sodium citrate ingestion on high-intensity cycling performance in repeated 45-sec bouts. Twelve subjects (9 male and 3 female) ingested either a sodium citrate solution (0.3 g x kg-1 body mass[BM]) or a placebo 90 min prior to exercise. Postingestion blood HCO3 concentrations were significantly higher in the citrate trial (p<.01), but there was no difference over the five bouts (p<.05) and postexercise blood lactate concentrations significantly increased over the five bouts (p<0.01), but there were no differences between trials. We conclude that sodium citrate ingestion (0.3 g x kg-1 BM) is not an effective ergogenic aid for high-intensity, intermittent exercise as simulated in this protocol.

Regulation of Citric Acid Cycle
The citric acid cycle is regulated in several ways, including feedback inhibition, regulation of enzyme activities, and associated anaplerotic or cataplerotic pathways.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
