Joint Hypermobility and Fatigue Are Associated With Injuries in a Group of Preprofessional Ballet Dancers.

Abstract

Strenuous preprofessional ballet training places young students at an increased risk of injury. This represents a major concern for aspiring dancers since a link has been described between injury and dropping out. It is therefore important to identify physical and psychological factors related to injuries in dance for prevention purposes. In this cross-sectional study, we explored the frequency and characteristics of injuries, as well as their physical and psychological determinants in preprofessional ballet dancers. Seventy-three participants (women = 75.6%; mean age = 13.7; SD = 1.8) were evaluated with the Beighton criteria for joint hypermobility and self-questionnaires assessing injuries in the last 18 months, fatigue, fear of injury, and motivation. Most of participants (61.6%) experienced injuries in the last 18 months, mainly in the lower limbs, and due to overuse. Multivariate analyses showed that joint hypermobility and fatigue predict injury status in this sample. These results confirm previous reports suggesting that physical factors such as fatigue and joint hypermobility, that are frequent in ballet dancers, should be taken into account in order to prevent injuries.
