Abstract

Introduction: Among the various possible movements in the hip joint one of them is the external rotation of the femur in the socket of the acetabulum. A high degree of range of motion is required for the perfection of classical ballet lines, and this is one of the principles outlined in the technique that is specifically described in the dancer's vocabulary: the en dehors' hip skill is an important fundamental physical attribute in classical ballet. Objective: to evaluate the degree of external and internal rotation of the hip region in classical dancers and to determine if they have a greater range of internal and external rotational movement in this region, compared to normality parameters in a control group. Method: 60 female volunteers aged 12 to 25 years, divided into two groups: A-group practitioners: 30 young people who practiced classical ballet for at least 2 years and B-control group: 30 young sedentary women. It was used to measure the degree of amplitude of the internal and external hip joint of groups A and B, a universal 360 degrees' goniometer, metallic, in a total circle. Results: According to the data collected, there was no significant difference between the groups, however we can observe angular differences in both groups. In the comparison between the degrees of external rotation of both lower limbs (LL), group A presented a mean of 34.6° in the lower right limb (LRL) and 32.8° in the lower left limb (LLL). While group B presented an average of 31.3° of rotation in LRL and 31.3° of rotation in LLL. In the internal hip rotation of both LL, group A presented an average of 36.6° in LRL and 41° in LLL. While group B, presented an average of 36° rotation in LRL and 37.4° rotation in LLL.
