salt tabs
I see salt pills or tabs mentioned on rec.running occasionally ... usually
in conjunction with longer endurance types of events. Whats the deal - are they supposed to help you retain water? electrolyte balance? But, I've never seen them mentioned here.... any input? good? bad? necessary? don't work? JK |

But even so, the salt tablet helped. Not so sure how useful they are for skiing, but I take one anyway before marathons.

Years ago, when I was putting in very high mileage weeks racewalking, I
had recourse to salt tablets; they worked. It was summer; I had been walking and drinking a lot and yet, one day I felt horribly stiff, just could not loosen up - like my muscles did not want to work. Electrolytes? I went home and took two salt tabs and a lot of water. The next day I was OK. From then on I included a tab a day during warm weather and, as JFT mentioned, before long races. Supposedly taking salt tabs can be bad for your stomach - creating a brine pocket - if you do not take enough water with the tab. One also has to take them, in a sense, BEFORE the body needs them. General advice nowadays is to add a bit more salt to one's diet during the warmer weather, especially if one is planning lots of strenuous work. And drink more water. My little experience recounted above was before the onset of the many "sport drinks" that are available. Nowadays I keep a few quarts of Gatorade in the fridge and drink'em regularly (mixed 50/50 with water) as well as adding a bit extra salt.

Whats the deal - are they supposed to help you retain water? electrolyte balance? Yup, the idea is to replace electrolytes and keep them in balance. As mentioned by JFT and Pete, I'm not real big on just salt tabs. Too much water, and you get hypokalemia. Too much salt and not enough water, you still have an imbalance. http://www.hmc.psu.edu/healthinfo/h/hypokalemia.htm for more on hypokalemia. For the Chippewa Tri this year (6hr event), I mixed a gallon of Cytomax about 2/3 strength, and added in a packet of Gookinaid ERG, to boost the electrolytes. I went thru 3 liters of that mix during the canoe and bike legs, and then just did water and Gu the last hour (run). I also used 4 or 5 Gu during those legs. Seemed to work out pretty well. I didn't seem to crust over as badly as I've done in the past and recovered a lot quicker. On the whole, I probably could've just used Gatorade with the Gookinaid.

Too much salt and not enough water, you still have an imbalance. http://www.hmc.psu.edu/healthinfo/h/hypokalemia.htm for more on hypokalemia. With regard to the original question, you should only need to take additional salt tablets if the fluid you are using to replace your losses is hypotonic (e.g. water). Modern sports drinks are very close to isotonic with respect to the concentrations of major/important physiological electrolytes. So if you're drinking Gatorade, Powerade, Sports Plus, etc., additional salt tablets are unlikely to be of benefit. It's worth remembering that during heavy exercise you lose fluid not just by sweating, but by a dramatic increase in so-called insensible losses (the most significant being via your lungs). This is particularly notable in a sport like x-country skiing where you're typically going your hardest in a rather dry / low humidity environment (you saturate every breath of dry air you take in to 100% humidity before you exhale it again). This loss involves negligible electrolytes (you're pretty much losing pure water) and therefore you actually increase the overall "saltiness" of your body. In this context, with modern sports drinks, taking extra salt tablets is not necessary and even counter-productive. With regard to hypokalaemia... Water intoxication (drinking heaps of plain old H2O) can be very dangerous, but the danger comes from hyponatraemia (low sodium) and _not_ hypokalaemia (low potassium). Your body can easily compensate for the diluted plasma [K+] by shifting it from the intracellular to extracellular compartment, however in the face of massive amounts of incoming water, it just can't keep up with the alteration in sodium concentration, and this is a very very bad thing for the human brain.

Why is it that I cramp less in bike races of two hours or more if I take a salt table before? I drink Gatorade, PowerAde, HydraFuel, etc and never drink plain water. Is it a placebo? I doubt that. I was pretty sceptical and only started about three or four years ago (after over 10 years of racing).

You loose a lot of plain old salt in warm weather. While I don't race any more, I ride centuries in 80-90 degree weather and I've found that there just isn't enough sodium in standard sports drinks. I've taken to adding a pinch of salt to my Cytomax and that seems to help a lot. In the winter, doing long days in the backcountry, cytomax by itself seems to work well enough to avoid those back to the car cramps, but in the summer I need more salt than just Cytomax. The latest version of Powerade basically follows this same formula[1], but it still tastes like crap to me so I've take to adding a bit of salt to the Cytomax. _ If you finish the day with that crusty feeling, you need more salt. _ BWT, my 50K trail running friends all use some kind of salt tablet and water. Their theory is that all the drinks get hard to consume after a while and it doesn't matter how good it is for you if you can't swallow it. It's definitely got me thinking, the longer into the ride, the more I prefer plain water. But plain water with no salt is not what you need at that point, I've taken to carrying pretzels, but salt tablets might be simpler if you have the discpline to drink enough water. _ Booker C.

Very informative thread. Serious question: do any of you know about how
long the body takes to absorb/disperse salt when taken as a salt tab? I guess that the actual statistic will vary with each person as well as each situation but I expect that there are some benchmarks. Pete Terje Henriksen wrote: Booker C.
