The effect of sodium bicarbonate supplementation on continuous and Interval anaerobic performance on active girls

The aim of this study was to investigate the effect of sodium bicarbonate supplementation on the performance of continuous and intermittent anaerobic function in active girls.

The present study was a quasi-experimental, applied and single-blind cross-sectional study. In this study, 12 active girls from Ahvaz participated in this study voluntarily. Subjects performed a continuous test (first week of supplementation and then 3 days of placebo again) and periodic testing (first week of supplementation and 3 days of placebo again) for two weeks. 90-60 minutes before the tests, the supplement group consumed sodium bicarbonate (0.3 g / kg body weight) and the placebo group consumed sodium chloride (0.045 g / kg body weight). Blood lactate level was measured 5 minutes after continuous and intermittent anaerobic activity. Also, the two variables of fatigue time in the continuous test and mileage in the periodic test were calculated..

The results showed that after consumption of sodium bicarbonate in blood lactate indices after both intermittent and continuous anaerobic activity and also the distance traveled by periodic activity, a significant difference was observed between placebo and supplement (P < 0.05). However, no significant difference was observed in the time index of fatigue and continuous activity (P ≥ 0.05).

The results indicate that consumption of sodium bicarbonate at a dose of 0.3 g per kg of body weight improves the interval anaerobic performance in active girls.
