What the study found
Sodium citrate altered acid-base measures and fluid retention but did not significantly improve 5-kilometre performance, temperature response or perceived effort.
Participants and protocol
Sixteen trained, non-heat-acclimated men completed sodium-citrate and placebo trials in a warm chamber using a double-blind crossover design.
What this cannot establish
Physiological changes are not the same as a performance benefit. The tested supplementation is not a personal recommendation, and the study does not show that sodium citrate prevents heat illness.
