Abstract

ALBUQUERQUE, Patrícia Arruda de  and  FARINATTI, Paulo de Tarso Veras. Development and validation of a new system for talent selection in female artistic gymnastics: the PDGO Battery. Rev Bras Med Esporte [online]. 2007, vol.13, n.3, pp. 157-164. ISSN 1517-8692.  http://dx.doi.org/10.1590/S1517-86922007000300006.

The artistic gymnastics (AG) is based on a wide range of motor activities that require specific capacities. However, tests to detect the potential for its excellence in early ages are still lacking. The purpose of the present study was to develop a test for talent selection in female artistic gymnastics. The activities used by Brazilian specialists were investigated by questionnaire and the international literature was reviewed. The 30 mentioned activities were compiled in a 22-test battery that was applied in 55 children of 5 to 9 years-old. Results obtained were treated by principal component factor analysis. Individual factor scores were extracted from the first factor, which were adopted as an indicator of the performance potential in artistic gymnastics (PPAG). At last, a stepwise multiple regression was calculated, using the factor scores as independent variable, producing an equation with eight activities to estimate PPAG. Construct validity, cross validity and reliability of the equation were tested. Sixteen experienced gymnasts and 19 apprentices were tested for cross validation. Mean PPAG found for the gymnasts (85.11) was significantly higher than data for the apprentices (54.80), indicating that the battery can discriminate the performance potential. Construct validity was confirmed by exploratory factor analysis, suggesting that the activities were related to a similar dimension of motor performance. Inter- and intra-observers reliability was tested by linear correlation and Student t test. The correlation values ranged between 0.83 and 1.00 (p < 0.05). No differences were detected between the means in all test situations. In conclusion, the application of the proposed battery revealed to be fast and simple, as well associated with low cost and easy understanding. Furthermore, data suggested that it has good validity and reproducibility, authorizing its application in initial talent selection for AG. However, additional studies should be conducted to confirm these results, including more important samples and longitudinal approaches, in order to verify the predictive validity of the method.
