Hello, I was wondering if you have ever heard of it and why it happens.

This is actually the only time my muscles cramp: when I shorten them by virtue of the position I put them in- but not actually using them.

And example is a hamstring cramp when doing the standing one legged quadricep stretch- that hamstring is being shortened but not doing anything and sometimes it cramps- but only the right.

Ditto for standing upper back stretch I do in a dance class. We turn our torso about 30 degrees to the side and then gently lean forward to stretch the upper back. Well this also contracts my internal obliques and they will often cramp- but only the right

Another example is when laying supine in bed after a hard day of dancing, if I bend my right leg and lay it out to the side to make a figure 4 with the left leg straight, some inner thigh muscle- not sure- the sartorus\(?) it will cramp like wild- very painful really. But again, only right side. weird.


anyway, I was just wondering if this is a well known phenomenon.

just curious

thanx
