When I was in kindergarten I remember one of my classmates coming in and saying that her mom took her to get some shots in her legs (she pointed to her inner thighs where I feel it stretch if I do the butterfly stretch) so she could do the splits. She then did the splits.

Do such shots actually exist or was this girl making things up? I've been wondering this for about 17 years.

Ow. I've never heard of it, and I know goalies who would gladly get shots to do the splits. (I'm not one of them). Not calling your kindergarten friend a liar, but if anyone's heard of it, I would love to learn more about that.

Lies.

I don't see how a shot would EVER elongate actin-myosin connections (sarcomeres).

Never heard of anything like this, and if it were available (and FDA approved to the point where a 5 yr old could get one legally) my sport would be all over it. She could do the splits because she stretched, and/or had natural flexibility.

Maybe Botox? (j/k)

More seriously (but not seriously considering), would some sort of cortisone or other steroid produce a relaxation of the connective tissue? A woman's body undergoes hormonal changes during pregnancy that significantly relax and allow stretching of the tissues in the hip area (enough to allow a baby throught the birth canal).

Maybe some sort of similar modification of the hormones?

David does have a point, a woman's body undergoes some SERIOUS stretching in a very short time during birth. And typically if all goes well, there's no tearing.

Ahh, but that is a stretching of connective tissue, not something you really want to stretch. We want flexible joints that have large ROM, not loose joints.

The uterus (sp) is all muscle, and that bad boy stretches the opening from like zero centimeters up to 10 centimeters in a matter of hours, sometimes minutes.

I'm going to guess that this was a normal five-year-old case of "correlation /= causation"

Aren't there cases of locked shoulders that are treated with shots to relax the muscles?

I remember reading about shoulder rehab, where the shoulder muscles are very tight and prevent ROM. Patients receive a shot in the muscle to "numb" it, and viola, full ROM can be achieved in the patient.

Unfortunately I don't know more about it than that, but it sounds like what Eric was asking about.

EDIT:
I did some quick research and came up with this:
http://www.mayoclinic.com/health/frozen-shoulder/DS00416/DSECTION=7

Apparently, in "frozen shoulder" cases, a general anesthetic can be administered that will allow full ROM to the limit of the muscle length.
