PURPOSE This study investigated the effect of ingesting 0.3 g/kg body weight (BW) of sodium bicarbonate (NaHCO₃) on physiological responses, gastrointestinal (GI) tolerability, and sprint performance in elite rugby union players. METHODS Twenty-five male rugby players, age 21.6 (2.6) yr, participated in a randomized, double-blind, placebo-controlled crossover trial. Sixty-five minutes after consuming 0.3 g/kg BW of either NaHCO₃ or placebo, participants completed a 25-min warm-up followed by…

The effects of sodium bicarbonate supplementation on asoccer specific conditioning test in division III soccer players

Objectives: This study investigated the performance enhancing effects of bicarbonate ingestion on soccer specific performance. Design: A randomized and double-blinded study. Methods: Division III

Effect of Sodium Bicarbonate Supplementation on Muscle Performance and Muscle Damage: A Double Blind, Randomized Crossover Study.

In conclusion, the NaHCO3 did not attribute benefits in performance or in parameters related to the internal load of exercise.

Topical Sodium Bicarbonate: No Improvement in Blood Buffering Capacity or Exercise Performance.

PR lotion was ineffective in altering blood buffering capacity or enhancing performance in either trained or untrained individuals.

Acute Effect of Sodium Bicarbonate Supplementation on Symptoms of Gastrointestinal Discomfort, Acid‐Base Balance, and Performance of Jiu‐Jitsu Athletes

It is concluded that sodium bicarbonate supplementation does not generate adverse responses resulting in gastrointestinal discomfort, and does not benefit performance yet promotes a state of metabolic alkalosis.

Effect of sodium bicarbonate ingestion on measures of football performance - with reference to the impact of training status

Correlational analysis suggests higher intermittent training status may potentiate NaHCO 3 efficacy, and individual variability in HIR response suggests this ergogenic potential is not realised by everyone.

Effect of sodium bicarbonate ingestion during 6 weeks of HIIT on anaerobic performance of college students

These data suggest that supplementation of HCO3− at the level of 0.2 g/kg body mass before HIIT training enhances the effect of HIIT on anaerobic performance, and improves the blood lactate clearance rate and the blood calcium clearance velocity following anaerilic exercise.

Acute effect of sodium bicarbonate supplementation by resistant training practices

SB supplementation by endurance training practitioners induces blood alkalosis, which reduces fatigue and possibly improves muscle strength endurance, when comparing pretest and posttest periods, significant differences were found between lactate concentrations.

Enhanced 400-m sprint performance in moderately trained participants by a 4-day alkalizing diet: a counterbalanced, randomized controlled trial

It is concluded that a short-term alkalizing diet may improve 400-m performance time in moderately trained participants and find higher blood lactate concentrations under the alkalized diet, suggesting an enhanced blood or muscle buffer capacity.

Effects of Creatine and Sodium Bicarbonate Coingestion on Multiple Indices of Mechanical Power Output During Repeated Wingate Tests in Trained Men.

There was no meaningful additive effect of creatine and sodium bicarbonate coingestion on mechanical power during repeated sprints and fatigue index was impaired in all conditions compared with placebo.

Acute effect of sodium bicarbonate supplementation on the performance during CrossFit® training

Acute NaHCO 3 supplementation did not improve performance during workout ‘Cindy’ in experienced men, and Supplementation also did not alter hemodynamic and perceptual parameters, nor did it cause any GSE.



Influence of sodium bicarbonate on sprint performance: relationship to dosage.

The results of this study show that incremental doses of NaHCO3 of and below produce incremental elevations in blood bicarbonate but do not produce improvements in performance for a sprint bout lasting 2 min.

Effect of Sodium Bicarbonate Ingestion on High Intensity Exercise in Moderately Trained Women

The results indicate that women athletes can use bicarbonate buffering to improve work and power output during high intensity exercise of 60 sec duration.

Sodium bicarbonate ingestion and its effects on anaerobic exercise of various durations.

The results indicate that NaHCO3 at this dosage has no ergogenic benefit for work of either 10 or 30 s duration, even though blood bicarbonate levels were significantly increased following ingestion of NaH CO3.

Effects of sodium bicarbonate ingestion on prolonged intermittent exercise.

The results of this study suggest that ingestion of NaHCO(3) improves sprint performance during prolonged intermittent cycling.

Acute versus chronic sodium bicarbonate ingestion and anaerobic work and power output.

Using chronic ingestion as a means to improve high intensity work rather than the acute ingestion of sodium bicarbonate is suggested, as it significantly improved work output two days after bICarbonate ingestion ceased.

Effects of chronic bicarbonate ingestion on the performance of high-intensity work

The addition of sodium bicarbonate to a normal diet proved to be of ergogenic benefit in the performance of short-term, high-intensity work.

Effects of ingestion of bicarbonate, citrate, lactate, and chloride on sprint running.

Bicarbonate is possibly more beneficial to sprint performance than lactate and probably more beneficial than citrate or chloride and recommended to enhance sprint performance.

Dose-related effects of prolonged NaHCO3 ingestion during high-intensity exercise.

NHCO3 administration for 5 d may prevent acid-base balance disturbances and improve performance during anaerobic exercise in a dose-dependent manner.

Acid-base balance during repeated bouts of exercise: influence of HCO3.

The alkalizing influence of oral HCO3 supports the concept that the hydrogen ion concentration in blood and muscle has a direct influence on performance during repeated, supramaximal exercise.

Induced metabolic alkalosis and its effects on 400-m racing time

The results suggest that NaH CO3 can be used as an effective ergogenic aid and support the speculation that the increased extracellular buffering afforded by NaHCO3 ingestion facilitated efflux of H+ from the working tissues, thus decreasing intracellular pH and hence offsetting fatigue.
