Once, a doctor told my wife (also a doctor) that tonic water (also known as quinine water) is good for relieving some cramps.
I’ve tried it and it seems to work. Seems to me that the quinine is a bit of a muscle relaxant. I’ve drunk quinine water before a workout, and it has ruined the workout, because I can’t contract my muscles as hard as usual.
I have a cramping problem with endurance events such as hiking or bicycling. After about 3 hours of continual pedaling or climbing a mountain, my hams and especially quads just start knotting up!
It hurts like hell and I can’t figure out what I’m not doing right. On every occasion it happened to me, I drank large amounts of gatorade and water. They have even happened to me when I was eating bananas as fuel during a long event.
I am guessing that it can only be attributed to two possble things.
Since I train heavy for legs, my rep range is never high enough to build the endurance qualities in my quads and therefore they cramp.
On almost every occasion, I was short on sleep (and used caffiene).
I know it’s not a lack of warming up, because it almost always happens after 3 hours.
I tried tonic water when playing soccer as a 17/18 year old - it seemed to work to an extent but didnt cure my terrible cramps, which forced me out of games after 60-70 minutes. However, cramps are not down to a lack of fitness, and in fact they are much more likely if you’re muscular. The solution for me was simple - I discovered that my sweat was extremely salty (I tasted it!). I added a 1/2 teaspoon of salt (sodium) to my normal energy drink pre-match and at the interval and bingo…cramps cured. Try it.
