We present HI observations of four giant low surface brightness (GLSB) galaxies UGC 1378, UGC 1922, UGC 4422 and UM 163 using the Giant Meterwave Radio Telescope (GMRT) as part of the study of seven GLSB galaxies in HI and radio continuum (Mishra et al. 2015). LSB galaxies are late type spirals, either blue or red in color, with diffuse stellar disk and wide range in morphology. We examine the morphology and the dynamics. HI is detected from all the galaxies and the extent is roughly twice the optical size and found the HI masses of the order of ≥ 109 M⊙. We combine our results with those in literature to further understand these systems. Recent star formation traced by near-ultraviolet emission in the GLSB galaxies in our sample appears to be located in rings around the galaxy centre.
