Sensores inerciais: Uma alternativa objetiva para classificação baseada em evidências do Basquete em cadeira de rodas

Abstract

The classification system for Paralympic sports has evolved with the improvement of evaluations, to make competitions fairer. With this, an international movement was developed to make the classification of athletes based on evidence. Such evidence can be obtained in different ways, such as tests and valid equipment for measures of variables related to classification. Thus, the main objective of this dissertation was to investigate the use of inertial sensors in the sportive classification process of wheelchair basketball. The dissertation was written in the aggregated model of articles and has two articles: a systematic review and an original study. In the systematic review, we observed that instruments such as kinematics, dynamometers and inertial sensors have been applied in the evidence- based classification in wheelchair sports, using variables such as strength, speed and acceleration to discriminate subjects from different classes. In our original study, we observed that: 1) higher class athletes performed performance tests in less time; 2) 16 variables showed moderate and strong significant correlations with the sports class; 3) the variables collected with the sensor positioned in the wheelchair presented a greater number of strong and moderate correlations with the sports class and; 4) the Illinois agility test showed more variables correlated with the sports class when compared to the maximum speed test of 20 meters and the anteroposterior axis of both sensors showed a greater number of variables correlated with the sports class. In summary, the inertial sensors seem suitable for assessing the sporting class. Finally, we believe that the use of technologies in the sports environment will grow more and it seems to be a path of no return, taking performance and competitions to other levels.
