摘要:AbstractThe goal of this work is to demonstrate how the motor imagery and video analysis can improve technical and educational aspects of the athlete in Aerobics, in which the speed and perfect execution of motor gestures is of fundamental importance. After dividing the control group and the experimental group made up of five athletes each, we have analyzed some mandatory elements for the junior A category (athletes aged 12 to 14 years). The control group is analyzed by the coach with evaluation boards, the experimental group analyzes step by step, the mistakes made evident in the video analysis trying to give, together with the coach, a new instructional strategy to enhance the motor gesture. Through the motor imagery the athlete imagines himself doing the movement previously corrected and then make the element of difficulty with the modifies mentally elaborated. Eighty % of the athletes in the experimental group increased their score from 0.1 to 0.3, while athletes in the control group improved 0.1. It is evident that the self-assessment with video analysis and a good practice of motor imagery can even increase minimum scores that are sometimes essential to win a competition.
