  We study the influence of Rydberg dressed interactions in a one-dimensional
(1D) Bose-Einstein Condensate (BEC). We show that a 1D geometry offers several
advantages over 3D for observing BEC Rydberg dressing. The effects of dressing
are studied by investigating collective BEC dynamics after a rapid switch-off
of the Rydberg dressing interaction. The results can be interpreted as an
effective modification of the s-wave scattering length. We include this
modification in an analytical model for the 1D BEC, and compare it to numerical
calculations of Rydberg dressing under realistic experimental conditions.
