Results
Twelve healthy male college athletes ingested either 26 mmol citrate or a placebo drink after a 400-m run. Blood lactate levels were monitored for 120 min after the ingestion. The blood lactate decreased from the post-exercise peak (approximately 15 mmol/L) to levels below 5 mmol/L at 40 min after both citrate and placebo ingestion. Citrate enhanced the reduction of blood lactate to make the concentration significantly lower compared to placebo at 20 min after ingestion (p < 0.005).
