Abstract # 1166
In a previous article of mine (Covering Your Nutritional Acids — And Bases), I discussed the benefits of eating foods that present the kidney with an alkaline load to balance out the acid loads imposed by grains and high protein foods. In this study, researchers used sodium bicarbonate to alter acid base status during anaerobic exercise.
Twenty-four men received placebo, 0.3/kg, or 0.5g/kg sodium bicarbonate for six days. Performance and acid/base status was assessed before and after Wingate testing. From this study, it appears that sodium bicarbonate supplementation improves mean power, allows for higher lactate concentrations, and maintains blood pH during anaerobic exercise.
Unfortunately, sodium bicarbonate often causes significant GI distress. Because of this potassium bicarbonate may be a better choice to avoid these problems.

Abstract # 1410
As discussed earlier, sodium bicarbonate ingestion can improve acute acid/base status during anaerobic exercise. In this study, the ability of sodium bicarbonate to impact training adaptations was studied.
Sixteen women were split into two groups and supplemented with either 0.4g/kg sodium bicarbonate or 0.2g/kg sodium chloride (placebo) prior to each workout during eight weeks of training. Training consisted of 6 to 12 two-minute high intensity intervals (performed three times per week).
During performance testing (after the supplement period), subjects that supplemented with sodium bicarbonate had greater improvements in total work and lactate threshold. As with acute supplementation, chronic use of sodium bicarbonate beneficially affects performance and performance adaptations. Again, it may be better to use an alternative buffer like potassium bicarbonate since sodium bicarbonate isn't easily tolerated in many subjects.
