Sodium citrate ingestion was investigated in order to determine the various effects it may have related to aerobic exercise metabolism and performance measures. Four cyclists underwent a placebo and experimental trial in which the subject ingested either a placebo or sodium citrate. Following a waiting period (30 minutes) the subject underwent a period of aerobic exercise, at 33% of the individual's maximum power output. After 30 minutes at 33 % of the individual's maximum power output the power output was increased to 66% of the individual's maximum power output. After the second period at 66% maximum power output, the power output was increased to 100% maximum power output. Power output, oxygen uptake, respiratory exchange ratio, heart rate, blood lactate concentration, and time to exhaustion were assessed. No significant differences (p<0.05) were seen in any of the dependent variables with the exception of heart rate. Two of the subjects experienced significant acute gastrointestinal distress following the trials utilizing sodium citrate. Sodium citrate showed no benefit as an ergogenic aid in aerobic exercise.
