Balance analysis in adolescents based on a motion capture platform

Abstract

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.

Gymnastics Movement Signs Based on Network Communication and Body Contour Feature Extraction

“…e second stage is the generation and judgment of new problems. When humans have a new problem, they will analyze and compare the new problem with the rules that have been summarized, predict the possible results of this problem, and judge the behavior that they are about to make [18].…”

A Kinematic Information Acquisition Model That Uses Digital Signals from an Inertial and Magnetic Motion Capture System

“…For this reason, starting from the fact that inertial systems provide information in technical language, this article proposes a method that allows the signals generated by an inertial-magnetic motion capture system to be converted into kinematic information (expressed in degrees corresponding to the specific movements of the body segment) that can be easily interpreted by professionals in the field of physical rehabilitation. To achieve this, the authors use a system named Imocap-GIS [27][28][29], which has been used in several projects and has made a significant contribution to the use of inertial-magnetic motion capture systems [30][31][32][33][34]. The use of this technology allows the use of a method to obtain kinematic information directly, reducing the required time, and lessening the data analysis and interpretation processes since specialized personnel and expertise are not always required.…”
