Method: A diagnosis was made using the direct observation technique and a pre-test by implementing a motion capture platform for the analysis of balance in order to obtain a quantitative and qualitative assessment of the study group. Subsequently, a basic gymnastics program was formed and implemented for a period of 12 weeks. Finally, the impact of the program was evaluated by means of a post-test using the motion capture platform that allowed obtaining a quantitative data and it was contrasted with the field diary by triangulation technique to verify the progress in the level of balance in the students. Results: The quantitative analysis showed improvement in balance on the three-body axes with an average of +/- 5.23°. Furthermore, according to the observations made in the field diaries for each session, they showed that the basic exercises of educational gymnastics, as they were practiced, improved body control. Conclusion: The gymnastic movements practiced within the proposed program caused constant imbalance responses, which originated a positive stimulation in the systems involved in stability improving kinaesthetic awareness, spatial coordination, and postural tonicity in the research group.
