Brief Summary

This was a randomized, double-blind, placebo controlled, crossover trial. The study aimed to assess the effect of sodium bicarbonate on the ability to perform a repeated sprint task by female football players. The researches hypothesis was that sodium bicarbonate increases the ability to remove lactic acid from muscle cells reducing its intracellular accumulation and increasing energetic efficiency resulting in the increase of peak power output, mean power output, or total work or in the decrease of the sprint decrement in each set of the repeated sprints task.

Interventions

Sodium Bicarbonate DIETARY_SUPPLEMENT

Capsules containing 0.3 g/kg of body weight of sodium bicarbonate were ingested in two doses. The first intake (0.2 g/kg) was performed together with a carbohydrate-enriched meal 2 h before a repeated sprint exercise protocol, and the second (0.1 g/kg) occurred 1 h later.

Placebo - Sodium Bicarbonate; Sodium Bicarbonate - Placebo

Placebo DIETARY_SUPPLEMENT

Capsules containing 0.3 g/kg of body weight of celulose were ingested in two doses. The first intake (0.2 g/kg) was performed together with a carbohydrate-enriched meal 2 h before a repeated sprint exercise protocol, and the second (0.1 g/kg) occurred 1 h later.

Placebo - Sodium Bicarbonate; Sodium Bicarbonate - Placebo
