Any thoughts on why some muscle knots "thunk" and some "crunch"? I was taught that the crunchy stuff was lactic acid but that myth has been busted. The only thing I could come up with that made sense was that it's the difference between the muscle belly and the bony attachments. Would love some discussion on this!
Here are two books that will help explain muscle cells and sliding filament theory of contraction. Very heavy science but after reading it in bits it will make sense.
Guyton's Medical Physiology. Saunders Publishing.
Exercise Physiology by McArdle, et. al. Williams & Williams Publishing.
As far as knots that "crunch"- most likely are adhesions. Fibroblast activity lays down collagen fibers; feels like sand to coco pebbles. And yes, there are lots of adhesions at the muscle-tendon junction.
Happy Friday 13th.

It's funny you should ask, Therese, because I recently received approval from the NCB for CE's on our first DVD. This DVD covers shoulder, axilla, ribcage, and upper back, and is available at our website, www.efullcircle.com, for a limited time at $125. This lowered price is due to some minor production issues, but the info is solid, and the DVD is approved for 24 CE's. We are working now on our second DVD, head and neck, with SMRT cranial sacral therapy. I too do cranial sacral, and I love the stuff. I have found that SMRT really takes it to a whole new level. And I too love working with less pain for the client and less stress on my body, its what has kept me in this business for 16 years with no physical issues.
I wasn't involved with this forum in 2011. So, permit me to reply to the original question, "What is a knot in a muscle?"
Knots-- noticeable, palpable knots-- can be cysts, soft or hard as a stone; can be a due to bruising and blood pooling in the tissue. And, hardly least, knots can be due to trigger point contracture. I agree with you and Travell that in the presence of a calcium "bath" surrounding the muscle motor endplate that isn't reabsorbed properly, a contracted muscle can't relax.
