Actually there's three kinds of ropes one might hang an adult human from.
A rock climbing rope is designed with a great deal of stretch. Thus when someone falls the rope decelerates them slowly, thereby lowering the peak force applied to the rope. To find these google "dynamic climbing rope".
Ropes used in rescue are not intended to catch falls. Accordingly they are designed with much less stretch. This makes for a more comfortable ride. To find these, google "low stretch rescue rope" or "static rescue rope".
Ropes used for execution are the third type. With these, safety is not a great concern.
