Lumbo-pelvic stability and electromyography of abdominal muscles in ballet dancers

Evaluating the ability to rectify and maintain lumbar adjustment can contribute toward the understanding of the behavior of abdominal muscles and their participation in the stability of pelvic muscles in dancers during the posterior pelvic tilt and double straight leg lowering tests. Nine healthy volunteers (male and female ballet dancers; age mean: 25.9 ±7.37 years) underwent maximal isometric voluntary contraction (MIVC), isometric voluntary contraction at 50% of MIVC, posterior pelvic tilt (PPT) and double straight leg lowering (DSLL) tests. The tests were carried out in a single day, with 3 repetitions each. During the tests, electromygraphic signals of the rectus abdominis, obliquus internus and obliquus externus were recorded. The signal acquisition system was made up of bipolar surface electrodes, electrogoniometer and an electromechanic device (pressure sensor), which were connected to a signal conditioner module. Root mean square values of each muscle during the DSLL and PPT were converted into percentage of activation of 50% MIVC. Lower back pressure was submitted to the same process. ANOVA with repeated measures was performed, with the level of significance set at p < 0.05. The results revealed that all dancers were able to maintain posterior pelvic tilt and there was trend toward greater activation of the bilateral obliquus internus muscle. In an attempt to keep the pelvic region stabilized during DSLL, there was a greater contribution from the obliquus externus muscle in relation to other abdominal muscles.

Evaluation of movements of lower limbs in non-professional ballet dancers: Hip abduction and flexion

Background: The literature indicated that the majority of professional ballet dancers present static and active dynamic range of motion difference between left and right lower limbs, however, no previous study focused this difference in non-professional ballet dancers. In this study we aimed to evaluate active movements of the hip in non-professional classical dancers.Methods: We evaluated 10 non professional ballet dancers (16-23 years old). We measured the active range of motion and flexibility through Well Banks. We compared active range of motion between left and right sides (hip flexion and abduction) and performed correlation between active movements and flexibility.Results: There was a small difference between the right and left sides of the hip in relation to the movements of flexion and abduction, which suggest the dominant side of the subjects, however, there was no statistical significance. Bank of Wells test revealed statistical difference only between the 1st and the 3rd measurement. There was no correlation between the movements of the hip (abduction and flexion, right and left sides) with the three test measurements of the bank of Wells.Conclusion: There is no imbalance between the sides of the hip with respect to active abduction and flexion movements in non-professional ballet dancers. © 2011 Valenti et al; licensee BioMed Central Ltd.

O uso do ballet nos treinamentos de alto nível da ginástica rítmica

Entre as inúmeras definições da ginástica rítmica podemos apresentá-la como arte e como desporto. Como arte ela é conceituada como a busca do belo, uma explosão de talento e criatividade, em que a expressão corporal e o virtuosismo técnico se desenvolvem juntos, formando um conjunto harmonioso de movimento e ritmo. Como desporto ela é uma modalidade esportiva essencialmente feminina, que requer um alto nível de desenvolvimento de certas qualidades físicas, com exigências de rendimento elevadas, objetivando a perfeição técnica da execução de movimentos complexos com o corpo e com os aparelhos.

Perfil cinético do movimento pirouette do ballet clássico em bailarinas experientes e não experientes

A dança é uma das formas de expressão artística mais antiga da história da humanidade. O movimento da dança em foco no presente estudo foi a pirouette do ballet clássico. Tal movimento é caracterizado por um ou mais giros em torno do seu próprio eixo, executado sobre uma perna seja em meia ponta ou ponta completa, enquanto a outra está flexionada, com o pé abaixo do joelho da perna de apoio. O presente estudo consistiu em examinar o perfil cinético do movimento pirouette de bailarinas experientes e não experientes no Ballet Clássico. A hipótese é de que as variáveis relativas à força para produzir o giro influencie na realização do pirouette. As participantes do estudo foram convidadas a realizar o pirouette sobre uma plataforma de força. Os resultados do presente estudo demonstraram que as bailarinas experientes aplicam maior força para iniciar o giro em relação às participantes não experientes. Em conjunto, os resultados do presente estudo sugerem que a força vertical aplicada para iniciar o giro, a qual denominamos impulso inicial, parece ser determinante para a boa performance no movimento pirouette da bailarina. Os resultados do presente estudo oferece uma importante contribuição aos técnicos e professores de dança de forma a valorizar questões de controle motor e postural no processo ensino-aprendizagem do pirouette

Signalling ballet in space and time.

Although we have amassed extensive catalogues of signalling network components, our understanding of the spatiotemporal control of emergent network structures has lagged behind. Dynamic behaviour is starting to be explored throughout the genome, but analysis of spatial behaviours is still confined to individual proteins. The challenge is to reveal how cells integrate temporal and spatial information to determine specific biological functions. Key findings are the discovery of molecular signalling machines such as Ras nanoclusters, spatial activity gradients and flexible network circuitries that involve transcriptional feedback. They reveal design principles of spatiotemporal organization that are crucial for network function and cell fate decisions.
