Working out and gathering knowledge
Day 1 Cycle2
Went to collect a new series of data points without jeopardizing the protocol.
30 minutes in conditioning vac stretch with gradually increasing weights in 10 minute intervals 1, 1.6 and 2kg
Followed with a US heated 20 min stretches left and right with a workload of 3,1kg for ten minutes and 4 kg for another ten.
There was that I found the excessive weight for heated sessions to be 4kg.
Warning signs appeared as there started to be sudden feelings of pain and cramping.
Anyways the stiffening of the tissues started to show and the transitional region have been completely achieved.
For the safety of the protocol I will back off one step and for the future I will use 3kg load as maximum for the heated part of the session.
Manual stretching routine for a 10 minutes.
Usual 30 second pulls for 5minutes but now with 5kg maximum.
This was achieved using vac attachment and luggage scale as a tensionmeter.
Another 5 minutes with 6kg which is by the way the maximum for the penimaster suction cup.
For the 30 seconds pulls it is still manageable but I can´t see stretching for longer being possible.
Measured pre BPFSL 23.0 cm and post BPFSL 23.6 cm. Strain of 3.4%. (avg)
Day 2 Cycle 1
Collected few more data points and for now I have enough understanding about transition region.
30 minutes in conditioning vac stretch with stress relaxation for 30 minutes and 2kg.
Followed with a US heated 20 min stretches left and right with a workload of 3,0 kg for ten minutes each direction.
It felt comfortable enough so the load is now on fixed to 3kg.
Measured pre BPFSL 23.1cm and post BPFSL 23.6cm. Strain of 2.9%. (avg)
Day 3 Cycle 2
NA
OBSERVATIONS
The visco elasticity is seen clearly on the difference of strain using ~9kg load as tissues start to stiffen in the accelerated rate versus 5 -6 kg loads instead.
Using lower load same strain percentage is achieved and still getting past the transition region, as indicated in the graph Strain 3.
Transitional region and the position of the kneepoint seems to be not altered.
I have pinpointed critical points and threshold levels I found to be productive in graph Stretch.
CONCLUSIONS
At this point I am convinced that the continuity of producing effective stretching past the transitional region is confirmed with the concept.
As for the heat and stress relaxation effectiveness, the transition of the knee point and the transitional region seems to found its limit for single exercise.
With these strains reaching the stiffening part of the slope, constant stretching for prolonged times start to be really uncomfortable.
Same goes for loads and the lowering of the loads seems to be productive enough. The threshold limit for the last part of the stretching yet to be found, but it is somewhere between 4-6 kg with 30 seconds cyclic stretches.
Conditioning stretch reach its maximum length at 30 minutes point with 2kg. This is the critical point where the heat should be introduced. If the stretch to be carried out for longer without heat, then stiffening of the tissues starts to develop after this point.
