The New York Times has an article today on cramping, examining what causes cramping and what MAY alleviate it or prevent it. The conclusions are not so good.
First, it doesn't seem dehydration plays such a huge part in causing cramping. That surprises me. It does seem that general fatigue to the point of failure contributes a lot. And that is interesting.
How do I use this information? Don't fatigue myself. Yeah, right. Actually, the article did go on to say that, while pickle juice itself probably does not help, jolting the nerve firings to the muscles can help once cramping sets in. Stretching specific cramping muscles can re-fire the nerves and stop the cramping.
Or just take some pickle juice. And forget the bananas and water. Go figure.
The eggheads always have the answers....
