    Vastus medialis cramps ?s

    I am having a bout with cramps in the vastus medialis muscles of both legs, or the teardrop muscle as it is commonly know. The big muscle on the inside of the thigh just above the knee.

    Here is a link to a diagram: http://en.wikipedia.org/wiki/Vastus_medialis

    This has happened 3 times this year and is usually during a good but not impossible climb. Has happend both seated and standing. The cramping is in both legs at the same time. I was told that moving the seat back and up a bit will resolve this issue. The only way to get the cramping to end was a 10 min. break off the bike.

    Anyone have some advice on this issue as related to riding position. I have read all the posts on supplements for cramping so that is already covered.

    You could look into trigger point therapy which is more or less reducible to getting a foam cylinder- available at many sporting goods stores, now- and rolling back and forth over your VMO. Here's a pic from this site.

    Had one in my sleep last night. Don't know how to fix it yet, but I feel for ya.
    Reacting is mind candy; it requires no thought. Thinking is tedious.

    I'm no Dr Butt......

    I hate to say it, but it could well be a kinking of the external iliac artery, which is not 'totally' uncommon in cyclists, because of the unnatural position of riding a bike. The kinking causes temporary and/or intermittent claudication of the inside leg muscles (particularly the vastus medialis), often during hard efforts, resulting in a cramp-type discomfort.

    Among other pros, Stuart O'Grady had it:

    Most general practioners and physiotherapists don't know much about it, mostly coz it is, as far as I know, a condition unique cycling, and even then, only a very small percentage

    I have the condition -- that is, I have it either minimally, or intermittently, or not as bad as I used to; I'm not sure. I spoke to my doctor about it a while ago, and i decided at the time that I wasn't serious enough about my riding to have my arteries sliced open . For some reason, mine never occurred when I was in an 'adrenalin-fueled' situation, such as a race or a competetive group ride, so I started working my hard days around group rides and races. It seems with that adrenalin, or perhaps some other hormone, prevents it happening with, however, after some hard days my mediali are more sore than my other muscles.
