SUMMARY:

Classical ballet is an art form that requires a combination of artistic skills, emotional expression and athletic performance. Maintaining proper posture is necessary for its practice, as it is a discipline that demands a high level of body control, strength, flexibility, endurance and technical precision. The requirement for correct posture and proper alignment also contributes to the demand on the musculoskeletal system. Dancers are trained to keep their spine erect, shoulders aligned, pelvis stabilized, legs and feet positioned correctly. This requires a balance between muscle strength and flexibility, as well as precise body awareness. However, little is known about the relationship between biological maturation (BM) and time spent practicing ballet and the presence of postural deviations in both the trunk (anterior and posterior) and the lower limbs (LL). The aim of this study was to find out how maturation and time spent practicing are related to postural changes in the trunk and lower limbs of children and adolescents practicing classical ballet. The sample consisted of 18 dancers (8-14 years old). The somatic maturation protocol analyzed by anthropometry was used to verify maturation, while postural deviations in the anterior and posterior trunk were analyzed by photogrammetry. The BM showed a significant difference with postural deviations for the posterior trunk symmetry index (POTSI), but not for the anterior trunk symmetry index (ATSI) or for the lower limbs - verified by the tibiofemoral angle (TFA). According to the POTSI, ATSI and TFA related to more or less mature dancers we found: ATSI (effect size: 0.2); POTSI (effect size: 0.6); TFA (effect size: 0.08). We found no significant differences when comparing the ATSI (effect size: 0.5), POTSI (effect size: 0.2) and TFA (effect size: 0.01) of those with less time practicing and more time practicing ballet. We conclude that biological maturation only influences postural deviations in the posterior trunk and, although there is a trend towards a significant difference in terms of time spent practicing, the results do not allow us to infer a relationship with postural alterations in the anterior and posterior trunk in young ballet dancers.
