Análise funcional de membros inferiores de jovens bailarinas

Abstract

Objective: The main objective of this study was to analyze the functional performance of lower limbs of young dancers. Method: Thirteen healthy female dancers, aged between 14 and 17 years, from three different ballet schools in the city of Garibaldi-RS, were part of the sample. The sample number was established for convenience, through research in selected schools, according to the number of dancers and their availability to participate in the research. For functional analysis, the Y Balance Test (YBT) and the Hop Tests (horizontal jump, triple jump, cross jump and timed jump) were used. Three training repetitions and three test repetitions were performed for each test. The mean of the three values was used for analysis and for comparisons between members the paired t test was used; while for comparisons between members, the paired t test was used. To analyze the composite score of the YBT, the t test for a sample was used for comparison with the normative values. A significance level of p < 0.05 was considered. Results: symmetries between limbs were identified, that is, no statistically significant differences were found in any of the variables of the applied functional tests. However, it was found that the average value of the composite score of the YBT was below the 94% suggested by the literature as an ideal value. Final Considerations: The symmetry between the limbs indicates a lower risk of musculoskeletal injuries and it was probably due to the young age and the short time of practice in this modality. However, YBT composite score values below the normative value suggest an increased risk of lower limb injuries. The results of this research can contribute to the development of preventive programs and to improve performance and the productivity of ballet dancers. [resumo fornecido pelo autor]
