Leg-length in relation to selected ballet performance indicators

Abstract

It is unclear whether the modern ballet body stereotype of long limbs is advantageous in dance performance. Therefore, we investigated the relationship between leglength and selected dance movements representative of power, dexterity, and range of motion in ballet dancers at different competence levels. METHODS: The total of 10 recreational, 24 vocational, and 10 professional ballerinas volunteered. They were subjected to: a) lower limb-length measurements, b) power tests (vertical jump-sautés and unilateral countermovement jump-temps levé), c) dexterity tests (tendus and double battement frappes), and d) flexibility tests (lateral active and passive-développé à la seconde). RESULTS: For power, regression analyses revealed negative leg-length relationships in recreational dancers (p<0.05) and positive leg-length relationships in vocational dancers (p<0.05). We also found negative relationships between leg-length and dexterity in the vocational group (p=0.01). No significant predictions of leg-length on power, dexterity, and range of motion were found in professional dancers. Multiple comparisons revealed significant differences between groups only for dexterity (p<0.01) and range of motion (p<0.01). CONCLUSION: Based on selected movements representative of power, dexterity, and range of motion, the present exploratory data indicate that lower limb length is not a determinative criterion for ballet success. Further studies should investigate whether body stereotypes, such as long limbs, are linked to dance injuries. © 2017 Science & Medicine.
