1. A cord, comprising:
a tubular braided sheath comprising:
strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume; and
a core within the central hollow portion of the tubular braided sheath;
wherein:
the strands each have a tensile strength of about 8 cN/dtex or more;
when the cord is in a relaxed state, the tubular braided sheath has a substantially cylindrical shape having an outer diameter of from about 20 μm to about 5 mm and a volume of the central hollow portion, wherein the core does not completely fill the volume of the central hollow portion of the tubular braided sheath in the relaxed state; and
when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under longitudinal tension such that a volume of at least a part of the central hollow portion of the tubular braided sheath in the longitudinal tensioned state is less than the volume in the relaxed state;
in the longitudinal tensioned state, the inner surface of the tubular braided sheath contacts and cinches a surface of the core such that slippage between the core and the tubular braided sheath is reduced, and
wherein the core occupies greater than about 95% of the volume of the central hollow portion of the tubular braided sheath in the relaxed state.
