Popis: The effect sodium citrate ingestion had on 3,000-m running performance was examined. Nine elite multidisciplinary athletes (7 men and 2 women, age 27.8 +/- 4.7 years, height 176 +/- 11 cm, mass 70.9 +/- 8.7 kg) completed two 3,000-m trials. The trials were double-blind and randomly assigned for sodium citrate (0.5 g x kg(-1) body mass) and for sodium (NaCl, 0.1 g x kg(-1) body mass). Split times, heart rate (HR), and 3,000-m completion times were measured. Blood samples were collected preingestion, pre-exercise, postexercise, and 10 minutes postexercise and analyzed for lactate concentration. Blood lactate (LA) was significantly higher (p0.05) for the sodium citrate trial, both postexercise and 10 minutes postexercise. No significant differences (p0.05) in HR were observed between trials. Performance time was significantly faster (p0.05) for the sodium citrate trial (610.9 +/- 36.6 seconds) compared with the placebo trial (621.6 +/- 31.4 seconds). Sodium citrate ingestion improved 3,000-m running performance in elite multidisciplinary athletes; however, the high potential for gastrointestinal distress likely precludes the use of sodium citrate as an ergogenic aid among athletes.
