As the name implies, suspension rope is rope used to suspend a human body.
Since this rope has to support the entire weight of a human body, make sure you don't use old rope, as explained in the Rope Care section.
If suspension rope snaps, the body will fall to the floor while still bound, which could cause severe injuries.
Some professional kinbakushi use new ropes in suspension in order to smooth the ropes.
(The suspension rope is twisted)
If the rope is facing the opposite way, when you pull up the suspension rope, the two ropes will create friction and resistance, as well as slackness.
With that, the suspension rope should be secure. You can use excess rope to decorate, or simply tie it around until you use it up.
It may hard to understand what's going on in the below picture, but if you look closely, you will see that after fastening the rope around the carabiner, the rope was tied around the carabiner to keep the rope from getting loose.
Usually, when suspension ends, the suspension rope is held with one hand while the body is lowered, and the suspension rope is undone.
If a lot of pressure falls on the suspension rope, and the fastened part gets constricted, the knot will tighten, which makes it very hard to undo with one hand.
Do not tie the rope around the carabiner. Usually, the rope should only be passed through it.
Likewise, in the bottom picture, the rope hasn't been fastened to the carabiner at all, which increases the possibility of it falling due to too much pressure.
There are many different ways to fasten the rope, so I'll add more from time to time.
