Balance control, hamstring flexibility and range of motion of the hip rotators in ballet dancers

Abstract

Aim: The aim of the present study was to compare balance control, hamstring flexibility and range of motion (ROM) of the hip rotators between competitive and recreational ballet dancers. Methods: Sixty ballet dancers aged 12–18 were placed into two groups based on their technical level: competition group (CG, n = 30) and recreation group (RG, n = 30). The groups were then subdivided by age: CG 12–14 (n = 14) and CG 15–18 (n = 16); RG 12–14 (n = 14) and RG 15–18 (n = 16). The Star Excursion Balance Test (SEBT) was employed for the assessment of balance. Hamstring flexibility was evaluated using the popliteal angle test. A manual goniometer was used to evaluate lateral and medial passive ROM of the hip. Results: Differences between groups were found in the final SEBT score (p = 0.001) and hamstring flexibility (p = 0.02). The RG 15–18 demonstrated better balance control in comparison with the CG 15–18. The CG exhibited a greater degree of flexibility in comparison with the RG. Conclusion: Dynamic balance was better in recreational dancers, whereas hamstring flexibility was better in competitive dancers. The ROM was equal in both groups.
