Published in Scandinavian Journal of Medicine & Science in Sports
Methodology
Randomized controlled trial of oral salt capsules (113 mmol Na+, 112 mmol Cl-) vs cellulose placebo before and during a real half-ironman triathlon
Key Findings
Total race time was lower in the salt group (P=0.04), with higher post-race serum sodium and chloride (both P=0.03) and a trend toward less body-mass loss.
Conclusions
Oral salt supplementation lessened body-mass loss and preserved serum electrolyte concentrations during prolonged hot-weather endurance exercise.
Limitations
Small sample, field conditions with uncontrolled fluid intake, single event, no blinded performance verification
Outcomes Measured
Oral salt supplementation was effective to lessen body mass loss and increase serum electrolyte concentration during a real half-ironman.
