How does it work?
When we start doing any vigorous activity, our bodies break down the carbohydrates storage to be used for energy. Lactic acid is a substance that is a by-product of this metabolic process. Over time, more lactic acid continue to be produced, leading to higher levels of accumulation in the blood. Lactic acid accumulation in the muscles will cause it to feel fatigued or burning during a physical activity. Too much lactic acid in the blood can lead to a serious condition called lactic acidosis. You should be aware of this condition as it can be life-threatening.
This may be surprising to you but athletes had been using baking soda as a supplement since the 1970s. It is only recently that its usage has been popularized again. Baking soda acts to neutralize the lactic acid build-up in the body during a strenuous sports activity, delaying fatigue. There are still many types of research to be done to truly measure the effectiveness of baking soda in improving athletic performance, but the general consensus is that it does improve physical endurance.
