Efeitos da videomodelação sobre análise do desempenho do golpe seoi-nage do judô

Abstract

The objective of the present study was to evaluate the effects of videomodelation training, in addition to traditional Judo training, on the performance of the seoi-nage stroke for athletes of different age categories. In general terms, the videomodeling procedure consists in the participant watching in video one or more executions of a movement, being supposedly understood as an ideal model, and, in sequence, the same participant to repeat the movement. Three federated Judo athletes were selected as participants, who trained for at least a year and a half in a Fortaleza / CE gym: P1 - 16 years old, female; P2 - 12 years, and P3 - 9 years, both males. For each participant another athlete of similar age and biotype was selected to perform the uke - opponent function that falls during the projection of the stroke by the participant. The research design was that of single subject as its own control of the type reversal: A-B-A, typical of the methodological approach of behavior analysis. In phases A the participants were exposed to traditional Judo training condition and in phase B, also called intervention, in addition to the traditional training, participants were exposed to training by videomodeling - independent variable. The dependent variable, measured in all phases, consisted in the analysis of the execution performance of the seoi-nage blow projections. Shock executions were filmed from two synchronized cameras, the images of the recordings were scanned for two-dimensional analysis, and then notes were assigned for 41 characteristics of the execution of the coup. The characteristics of the execution of the coup were defined through an analysis process known as task analysis. The results showed that throughout the data collection all the participants presented increasing performances, but, in addition, the videomodeling procedure produced, for two of the three participants, more significant effects on the performance increase in the execution of the blows. For P1 and P3, the results of the intervention condition showed a steeper performance increase, respectively 12.9% and 12.7%, compared to both the antecedent condition, respectively 2.5% and 7.2%, and in Compared to the subsequent condition, respectively 7.5% and 2.2%. The discussion of the results was carried out in terms of the time of exposure to videomodelation training, previous experience in discriminating the most important elements of the execution of the coup, and then emitting answers with trustworthy correspondence (imitate), and also in relation to the degree of Subjectivity in the analysis of the characteristics that make up the execution of the blow by the experimenter. Although the application of the procedure has been shown to be effective in evaluating the effects of videomodeling on the execution performance of the seoi-nage stroke for athletes of different age categories, indicating methodological advances and greater rigor in the analysis of performance criteria, It is believed that there is a need for replications of this study. Future studies could be carried out with more participants, in order to evaluate the generalization of the effects of the intervention, and; Delineated from other logics of performance analysis considering the participant / subject as their own control.
