The Rasch model in the motor ability testing

Motor abilities are essential for the execution of many motor tasks. The purpose of this study was to introduce the Rasch analysis in the context of motor ability testing. To investigate the application of the Rasch model for the evaluation of motor abilities the Brace test (BT) was chosen. The subjects included 105 university students aged from 19 to 24 years. Test performance for all students on the BT was subjected to analysis for fit to a theoretical Rasch measurement model. The results indicate that BT is relatively homogenous with respect to its content. In addition Rasch analysis in the evaluation of motor abilities was examined. According to our results we can conclude that the Rasch model is a very powerful instrument in motor ability assessment.
