Methods: In 13 elite Japanese female ballet dancers (average age, 22 years), markers related to bone quality were investigated. These included: serum homocystein (HC), a marker of increased oxidative stress;pentosidine (Pent), a marker of glycation- or oxidation-induced non-enzymatic cross-links;markers of bone metabolism (bone alkaline phosphatase, BAP;tartrate-resistant acid phosphatase 5b, TRAP5b) and bone mineral density (BMD). It was determined whether there is a relationship between bone quality markers’ levels are related to amenorrhea and/or fatigue fractures. Results: Two dancers had fatigue fractures and 3 had a history of secondary amenorrhea. The average BMD was 1.305 ± 0.12 (g/cm2), in all these cases the Z-score was higher than -1.0. Although the serum levels of BAP, TRAP5b, and HC were normal in all examined dancers, in 2 out of 3 dancers with a history of secondary amenorrhea, pentosidine serum levels were increased. No relationship between bone quality markers’ levels and fatigue fractures was found. Conclusion: Latent deterioration of bone quality may occur in female athletes with secondary amenorrhea and otherwise normal BMD and calcium metabolism markers.展开更多

The specific training required from early years may cause some changes compared to the normal human anatomy and physiology. The aim of this study was to investigate the potential of motion analysis technologies for the evaluation of frequent changes in biomechanics of posture and dance. This paper presents an overview of the literature on the main postural compensation employed by the dancer; more specifically on the training effect of the fundamental basic techniques in ballet. It then focuses on the characteristics and potential of motion analysis technologies for the biomechanical evaluation of the dancer. The technologies investigated in this study are the optoelectronic system of gait analysis, which is one of the most advanced technologies for multifactorial motion analysis, integrated with the use of the force platform and the electromyography. These technologies enable a quantitative three-dimensional integrated multifactorial motion analysis in relation to kinematics and dynamics. Through specific systems of motion analysis, the instrumental analysis can describe objectively and with reasonable accuracy the biomechanics, the postural compensation, and the gait of the dancer.展开更多

Now, the enchanting ballet about the princess who is transformed into a swan by an evil curse takes on a unique collaboration. A gala perform- ance of the ballet jointly presented by Joburg Ballet of South Africa and Liaoning Ballet of China thrilled a full house at the Joburg Theater in Johannesburg on April 17. The sparkling event was the premiere of 21 joint performances the two ballet companies are staging in South Africa till early May.展开更多
