also reported during ballet practice and they are more frequent on the male practitioners due to the fre- quent holding of the female dan- cers on their arms during complex movements. 14 Regarding the mechanism of the traumatic injuries, the great majo- rity occurs during jumps (on the beginning of the movement, during air suspension or during the return to the ground), and the incidence depends on the range of motion: 9.9% of the injuries occurs during small jumps, 5.9% during medium and 9.0% during high jumps. Some typical more demanding exercises on the ballet are associated to a greater prevalence of injuries. The arabes- ques, a position in which the dancer rests his body weight over a lower limb and performs hyperextension and lifting of the suspended leg, are associated to 7.1% of injuries, while the portées, where the male dancer holds the female dancer on his arm in order she can make some motion suspended in the air, are associated to 5.2% of injuries (Figure 3). 17 The female athletes, in compari- son with the male athletes, have a greater incidence of isolated inju- ries without relapse and they have a lower rate of complications or sequels. 27 As far as temporality is concerned, it is more frequent an average window of 24 hours between the traumatic event and the report of the injury by the athlete. On the return to sport, the more serious injuries that require longer periods of rest or rehabilitation are the frac- tures of the tibia or of the metatar- sals (35%), chronic instability of the ankle (10%), facet syndrome of the lower back (9%) and low back radi- culopathy (9%). 28,29 Figure 3 – Typical movements of the ballet: A – Arabesque on the left side; B – Portée on the rightb side. 30 january 2019 www.revdesportiva.pt Conclusion The longer the time exposure to training sessions, the greater the frequency the dancers and the greater the severity, correspond- ing, therefore, to the professional athletes the greater targets for traumatic injuries in this sport. 1,2 These injuries afflicts several and different body parts of the athlete are they are intimately associated to the typical movements repeatedly performed on this sport. 2,14-23  The high incidence of injuries on profes- sional dancers demonstrates the need to implement and to develop preventive measures, to have an early diagnosis and to apply an early and adequate therapeutic regimen in order the athletes can return soon and in safe to sports practice. 1 There should be stimulated the realization of epidemiological studies about the traumatic injuries on this sport due to the eventual positive impact that these studies might have on preven- tion, diagnosis and early treatment of the injuries.
