A study has outlined that dietary supplementation with sodium bicarbonate (baking soda) before an important athletic event can give a boost to performance.

A randomized, controlled trial found that those players who received the supplement showed no decline in skilled tennis performance after a simulated match.

The nine players in the study were randomly assigned to receive either bicarbonate or placebo drinks. They then took part in a tennis skills test before and after a simulated match.

The skills test measured the accuracy and consistency of service and forehand and backhand ground stroke to both sides of the court.

The finding was reported in BioMed Central’s open access Journal of the International Society of Sports Nutrition.
