I came across another member mentoring use of heat throughout his day in an extender. As well as others using constant heat during stretch routines.
I have adapted this into both my extender and stretch routines. I will say I have noticed a difference.
My 2 main thoughts on it is this. The hotter it is, the easier and further you can stretch, but also the more strain it puts on.
For hanging especially, if you're going to experiments with heat during, I'd dial back the weight and reintriduce it slowly.
My second thought is based around the collagen studies on rat tails. Between methods of heat induced elongation vs long term traction, they found the best method was to
Heat, then stretch, then let cool in the stretched state.
So I have found this seems to be a benefitial effect with the extender. Warm up, put it on, then heat, increase length/tension, then let cool, then reheat, increase length/tension, let cool, etc.
I think a similar idea may be good for hanging. As it will allow periods of furthering the stretch by being hotter, but also reduce the damage caused by the increased intensity of the stretch in a heated state. As well as letting the tissue "set".
Its kindof like stretching a rubber band. If you stretch it 10 times in a row for 60 seconds each to its max length, it seems to end up looser than stretching it to its max and holding it there for 10 minutes. Im not sure why, but I think its like,
The initial stretch creates the pull on the tightest fibers, and attacks those. Every time you let it relax and restretch, it attacks the new tightest fibers, and so forth.
All theory but thats my experience. I will be following this hopefully we hear more about this subject
