Stretchers and Stress Relaxation
Stretchers with adjustable length rods work the tissues differently than hangers or stretchers utilizing weights or elastic bands. Stress relaxation vs. creep.
If you set the rods to a certain length, the tissues relax at that length after a period of time, and the tension reduces. This is stress relaxation. Then, you crank the rods out a little farther and allow the ligs to relax again, and so on. How are you guys going about retightening the rods? How often?
This page is interesting. Their protocol for treating joint contractures using a similar adjustable device is to begin with one 30 minute session per day for the first week, go to 2 30 minute sessions the second week, and 3 per day for the remaining weeks. Retensioning is done every 5 minutes.
I’m wondering if stress relaxing in stages like this holds any particular advantage over applying a constant load. Perhaps intermittent relaxation allows the ligs to lengthen more in a given time? Or lengthen more, period. Maybe we should be focusing on stress relaxation and creep alternately, or even both in a certain order during a single workout. I don’t know, but this has been on my mind for quite a while.
Seems to me that if a guy wanted to use both in one session, starting with stress relaxation would be the way to go. Maybe 30 minutes of the above protocol for an initial stretch, followed by an hour or more of hanging weights to wring fluid from the ligs and allow for creep.
Thoughts on any of this?
