Intervention model description: The study design employed is a randomized clinical trial (RCT), analytical, longitudinal and prospective, with a 4 months follow-up.
Primary purpose: PREVENTION

Brief summary: Introduction. After observing the lack of lumbo-pelvic control and the difficulty in identifying the musculature used when performing the different dance positions, it was decided to carry out an exercise intervention to strengthen the abdominal musculature and lumbo-pelvic stabilization with dancers of the Dance Conservatory of Murcia. Approximately 40 students in the 6th year of professional dance of the 4 specialties taught will participate in this study.

Objectives. To improve abdominal musculature, lumbo-pelvic stability, dance technique and proprioception, to favor the correct integration of the dancer's body scheme and muscular synergies, to reduce the risk of injury and to avoid muscular compensations in the specific Arabesque dance position.

Methods. In order to develop the study, two individual and specific assessments of the dancer will be performed, pre and post intervention. In these, data and personal history were collected, assessing joint ranges and asymmetries in the movement of upper and lower limbs, and musculoskeletal assessment of the spine, hip and knee was performed by orthopedic tests. Flexibility of the ischiosural muscles will be evaluated by means of the toes-floor test and the popliteal angle test, and muscle strength in the abdominal and lumbar region for the muscles most involved in the Arabesque movement. In addition, core stability will be assessed by specific tests and hip and knee extension range along with the increase in lumbar curve when performing Arabesque.

The intervention will be carried out through group sessions of 4 to 6 participants, and exercises aimed at muscle strengthening and improving lumbo-pelvic stability will be taught. The intervention will be performed 1 hour per week, with each group, for 2 months and they will be instructed to work this routine two hours per week at home.
