The factors on which human laterality depends have been studied for many years, and no conclusive result has been established so far. Sport is an area in which it is often intended to make changes in the laterality of athletes. We found studies that state that lateral dominance can be changed through training and the application of techniques for modifying motor behavior (Bilbao & Oña, 2006). We were looking to obtain an overview of the treatment of laterality in the training of Rhythmic Gymnastics, based on the opinions and experiences of coaches. A questionnaire was designed to collect information, with 83 coaches participating. The analysis describes the treatment that Rhythmic Gymnastics trainers give to laterality. The use of contralateral members favored by coaches is relatively frequent (60%), but usually does not produce changes on the skillful side.
