RESUMO

The aims of this study were: make the anthropometrics profile and body composition in classical dancers; Check through specific tests the flexibility, the agility, the explosive strength of lower limbs and the cardio respiratory capacity in the dancers; analyze the levels of blood lactate concentration blood and the its removal kinetics after two different specific classical ballet choreographic routines: adagio and allegro. So we studied 11 adolescents and 11 adult females dancers, between 14 and 31 years old. As inclusion criteria s it was considered the minimum period of eight years of dance practice and still be in the process of training. The body composition was assessed by the subcutaneous cellular tissue thickness technique. The measures of flexibility in different joints were obtained with a fleximeter, the neuromuscular capacity was evaluated by the measure of the agility (by Shutlle Run test) and the explosive power of lower members was obtained through a specific ballet jump in the Ergojump Test®, a jump platform. The assessment of the maximum cardio respiratory capacity and power was obtained through a treadmill dynamic test until the exhaustion. The effort intensity was measured during the choreographic routines through the blood lactate concentrations. The data are presented as mean ± standard deviations after the selection and organizations of results. The we proceeded with the descriptive statistics of individual data. The level of significance adopted was p<0,05. In body composition assessments the adolescents dancers obtained higher values than the adult dancers, but we must remember that it was used different formulas, due to the difference in age. It was possible to verify that there are problems in the validation of methods to estimate body composition in dancers and practitioners of dance. For the flexibility assessment the dancers showed satisfactory values and higher in comparison to other studies. In the agility test the adolescents dancers obtained the best results, while in the lower limbs strength test the adult dancers showed significantly higher values. The pulmonary ventilation on the treadmill test in anaerobic threshold between the two groups was not significantly different. But it appears that the special training of classical ballet does not reduce the ventilation response. Considering the 4mM methodology, we can verify that: the Adagio choreogaphic routine is at the anaerobic threshold, while the Allegro choreographic routine reaches the peak above the anaerobic threshold for the two groups. At Adagio the adolescents dancers achieved significantly higher values of lactate levels in all stages of passive recovery. According to the results found in this study, we believe that that additional studies are still required in order to make a better characterization of the classical ballet, especially at different times of periodization of the training
