Effects of Pilates Method in the Range of Ballerina's Turnout (PilatesTurnout)

Effects of Pilates Method in the Range of Young Ballerina's Turnout

A high degree of turnout is desired by many dancers, because enables an efficient weight transfer; provides an excellent extension and control; and reduces the risk of injury when used properly. The dancer's body conditioning is worked and acquired through various types of training, among which stands out the Pilates Method. Thus, the aim of the study is to determine the effect of a training program of Pilates Method in the range of ballerinas' turnout. The study will be conducted with young dancers, between 10 and 14 years, who practice classical dance twice a week. They will be randomly divided into two groups: intervention and control, but only the intervention group will do Pilates classes. To verify the extent of the turnout, tests will be applied in both groups, before the start of Pilates classes (pre-test) and after 24 sessions (post-test). In the evaluation protocol will be collected kinematic data, while performing the movements of demi plié and elevé. Anthropometric variables of height and body mass will be obtained; and also the extent of the passive and active turnout in dancers.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The change in turnout	Turnout is determined as external rotation of the coxofemoral joint, and is considered perfect when reaching an angle of 180 ° between the longitudinal axis of the feet. The change in turnout will be evaluated one week before the first session of the intervention and after 12 weeks of Mat Pilates training. So, the primary outcome is the change in the range of ballerinas' turnout.	One week before the first session of the intervention and 12 weeks after the intervention
