Brief Summary

Professional dancing requires an almost perfect control of technical skills, combined with a good physical condition. To meet the demands of choreography, dancers need an adequate aerobic endurance capacity, muscular strength as well as flexibility and motor control (Twitchett et al. 2009; Roussel et al. 2009). One could compare these requirements to those of an athlete. In contrasts to athletes, only few attention has been given to the prevention of injuries in dancers. Professional dancers are at high risk to develop musculoskeletal injuries, especially, soft tissue and overuse injuries to lower extremities and spine(Hincapié et al, 2008). Several potential risk factors for injury have been suggested, such as a reduced level of aerobic fitness, lack of muscular strength, hypermobility of the joints and altered motor control of the lumbopelvic region but no conclusive evidence exists for any of these items separately.

Applying sports science principles to dance training may improve the performances of the dancers (Twitchett et al. 2009). Dancers demonstrate low aerobic fitness and muscle strength, in contrast to the high demands. Aerobic endurance of dancers is for example comparable to healthy adults with a sedentary life style.

Fitness programs, additional to regular dance classes, have only recently been considered (Twitchett et al. 2009). The advantages of additional training in athletes is beyond questioning. Nevertheless, this concept is relatively new for dancers. On the one hand, professional dancers do not consider themselves as a sportsmen but as artists (Wyon et al, 2007). On the other hand, choreographers and dancers fear the negative influence of training on body aesthetics.

Additional fitness training could improve physical fitness & motor control and may help with stress coping during public performances. Therefore, the purpose of this randomized controlled trial is to examine whether an additional intervention to regular dance lessons influences the physical condition and musculoskeletal injury rate in professional dancers.

Detailed Description

Prior to participation, all subjects receive verbal and written information addressing the nature of the study. First dancers are asked to fill in a self-established medical questionnaire, the Short Form 36 questionnaire (SF-36), the Dance Functional Outcome Scale (DFOS), the Baecke questionnaire, the Pain Catastrophizing Scale (PCS) and the Tampa Scale for Kinesiofobia (TSK). After a baseline assessment, consisting of an evaluation of the physical condition (maximal exercise test, evaluation of the respiratory capacity & evaluation of explosive muscle strength using a field test), a motor control evaluation of the lumbo-pelvic region and evaluation of anthropometric measurements, the participants are randomly divided into 2 groups. They will receive an 4 months lasting intervention in addition to the regular dance lessons. The time schedule of the intervention is identical for both groups. Participants from group A receive an active program aiming at improving their cardiovascular endurance, muscular strength and motor control. The level for cardiovascular training is based on the results of the maximal exercise test performed during baseline assessment. The level of training is determined at a level of 70% of the predicted maximal heart rate and was increased every 6 weeks with 5%, ending at 85%. Heart rate will be monitored during the training.

Participants from group B will receive an alternative program, in which all active parts are replaced by passive interventions. Several education sessions will be given regarding different topics, such as stress management, nutrition, injuries, etc. In addition, also practical sessions well be held to practice massage, passive stretching, taping. The intervention will be supervised by physical therapists and master students in Physiotherapy, experienced in dancing, motor control and/or physical conditioning, and an attendance list will register the presence of the participants.

The injuries of the dancers will be registered during the intervention and during a 6 months follow up period.
