The aim of the present study was to investigate whether preexercise sodium-bicarbonate ingestion improves judo-related performance. The study used 2 different protocols to evaluate performance: 3 bouts of a specific judo test (n = 9) and 4 bouts of the Wingate test for upper limbs (n = 14). In both protocols athletes ingested 0.3 g/kg of sodium bicarbonate or placebo 2 h before the tests. Blood samples were collected to determine lactate level, and levels of perceived exertion were measured throughout the trials. The study used a double-blind, counterbalanced, crossover design. Ingestion of sodium bicarbonate improved performance in Bouts 2 and 3 of Protocol 1 (P < 0.05), mean power in Bouts 3 and 4 of Protocol 2 (P < 0.05), and peak power in Bout 4 of Protocol 2 (P < 0.05). Ingestion of bicarbonate increased lactate concentration in Protocol 1 (P < 0.05) but not in Protocol 2. Ratings of perceived exertion did not differ between treatments. In conclusion, sodium bicarbonate improves judo-related performance and increases blood lactate concentration but has no effect on perceived exertion.


Sample size is a bit small, but the results are significant (statisically).

So, who is going to start eating sodium bicarb before matches?

What the ****?

How the **** does an antacid improve your athletic performace? Wait. Of fucking course. Electrolyte balance? What's in the discussion section of that paper?

I think that article is bullshit. ****, if only I still had my subscription to PubMed. Does anyone with one want to tell me what it says?

From another paper's abstract: PURPOSE: Ingestion of sodium bicarbonate is known to enhance sprint performance, probably via increased buffering of intracellular acidity. (http://www.ncbi.nlm.nih.gov/pubmed/15235332)

Id read the original paper, but I dont have online full-text available for that journal.

Fuckin' A right. Nice find, kid. I like this thread.

In both protocols athletes ingested 0.3 g/kg of sodium bicarbonate ...

I weigh 185 lbs, which is about 84 kg. At 0.3 g/kg (of body weight, presumably), that's about 25 g of sodium bicarbonate. That seems like a lot to me. I did some quick searching to find the typical sodium bicarbonate dose in an over-the-counter antacid, but couldn't find it (I don't have any on me, but I'll check the dosage next time I'm at the store).

*EDIT*

Ok, I found this source of sodium bicarbonate in 650 mg pills (http://www.amazon.com/Sodium-Bicarbonate-Tablets-650-Concord/dp/B000NAZK20/ref=pd_sim_hpc_title_1). I would have to eat 38.5 of them to achieve the amount suggested. More convenient (maybe) would be to take sodium bicarbonate in powder form (http://www.amazon.com/dp/B000SUG5J2?smid=A1FRT2DFB93P69&tag=dealtime-hpc-20&linkCode=asn). Still, that's a lot.

Not necessarily. You could throw 25g of bicarbonate into a 500ml bottle of water and chug that sucker. Of course, this is going to do bad things to the pH of your stomach contents. Wouldn't this mess with some of it's antibacterial properties? It doesn't sound like a good idea. Man, I really need to read that paper. Someone get me that paper!

True, or you could drink it slowly over the course of an hour or so.

But something about this is not adding up:

HOW TO USE: Take this medication by mouth as directed. Chewable tablets are to be chewed thoroughly before swallowing followed by a glass of water. Take this medication exactly as directed. Do not increase the dose, take it more often or continue taking this for longer than prescribed.

SIDE EFFECTS: This medication is generally well tolerated. However, high doses may cause headache (http://www.medicinenet.com/script/main/art.asp?articlekey=20628), nausea or irritability. If any of these effects continue or become bothersome, inform your doctor. Notify your doctor if you develop: muscle weakness, slow reflexes, confusion, swelling of the feet or ankles, black tar-like stools, coffee-ground vomit. If you notice other effects not listed above, contact your doctor or pharmacist.

They don't say what constitutes an overdose, but I'm sure 25 g is getting up there. And from the sound of those side effects, it doesn't seem like it's performance-enhancing.

If someone got access to the actual paper, they ought to describe the method of ingestion in the methodology.

Yeah, I don't recomend starting an IV or anything, but it would be your quick delivery system of the concentration you'd need. :lol: Now that would look a little suspicious.

I harkens me back to my EMT mega-code or resuscitation protocols on a cardiac arrest- bicarb is at the end of the chain. As in a desparate measure. Trying to restart the stroke cycle in muscle tissue by pulling up all that lactic acid that builds up.

Leave this one to the guinea pigs for a while:qswim: . Interesting thinking though.

I take that much baking soda all the time for heartburn. I never feel like a super judo stud afterward. I just burp a lot.

Bicarb used to be the first drug in until they realized that a slightly acidotic ph got better results to drug therapy.

I wouldn't want to put that much sodium into my system on a regular basis.

For what its worth, I tried bicarbonate loading when i was in HS running 400s and 800s. It didn't help at all for the 400m, and helped maybe a little bit for the 800m. The real problem with it was the ability to use a consistant dosage without throwing up. I stopped using it when i went to undergrad because i couldn't have caffiene and baking soda before races (because the combination made me sick) and i have always have gotten more from caffiene than baking soda.

BTW, Never try mixing baking soda with lemon gatorade, the result is a stale lemon marange pie flavor......

2g of beta alanine 3x a day. Works very well and does not taste horrid. It accomplishes the same thing, but probably does it better. Buffers acid and crap by increasing your carnosine levels.
