This Master's project aims at analyzing and possibly contributing to the topic of motion of extended bodies in curved spacetimes. Particularly, we are interested in the swimming effect in curved spacetimes, by which an articulated, free extended body can propel itself through empty space by performing ciclic deformations. Although this effect already appears in the context of Newtonian gravity, relativistic effects can contribute in peculiar ways. Our goal is to apply an explicit covariant formalism in order to analyze these contributions, which differs drastically from the approach employed in the literature. (AU)
