Context: The objective of this research was the creation and implementation of a gymnastic program to improve the level of balance in high school students. 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.

An assessment of the level of balance in adolescents was done, using motion capture technologies (IMOCAP). The sample was 7 peoples, to whom a pre-test and then a post-test and intervention program were applied. The duration of the intervention program was 11 weeks, with a weekly basic gymnastics' session of 120 minutes. A diagnosis of anthropometric factors was carried out on characteristics such as size, with an average of 1.62 cm. (SD = 0.059), weight, with an average of 54.12 kg. (SD = 6.89) and age, with an average of 15 years with SD = 1.11. Consecutively, a pre-test for static balance was applied, using IMOCAP. An intervention program was designed, with the aim of improving corporal stability. Afterwards, the post-test was applied using IMOCAP. There was an improvement in the execution of basic gymnastic movements and greater stability was perceived. This was confirmed by the results registered by the instructor and the measurements generated by IMOCAP, which indicated a lesser degree of inclination and rotation of the torso in the post-test (+/-7.35° and 3.7° on average) for the three body axes. Most of the basic gymnastic movements help to improve body stability, corroborated by a high-precision, reliable platform with quantifiable result-delivery.
